The intravenous form wears off faster than the oral form, so more frequent dosing may be required than is usual with oral metoprolol (e.g. However, calcium is an excellent inopressor in any patient, so I heartily agree that it would be a great thing to give in the patient above. the initial loading dose may be repeated q4hr-q6hr, depending on heart rate and blood pressure). Read unlimited* books and audiobooks on the web, iPad, iPhone and Android. Classification of atrial fibrillation. In the context of post-surgical AF, RCTs have demonstrated that magnesium administration reduced the incidence of AF with an odds ratio of 0.55. >200). Usually start with 5 mg IV, which should take effect within ~5 minutes. Written by Thomas Davis. Ian Stiell and colleagues are back at it with atrial fibrillation; The RAFF2 trial (Electrical versus Chemical cardioversion for Emergency Department patients with Atrial Fibrillation (RAFF2); A partial factorial randomized trial) was published in The Lancetthis week. Another obscure but cool-sounding strategy I have actually done a few times is to pretreat with CaGluconate then give small (5mg) Diltiazem boluses. It only matters if the patient is demonstrating antidromic conduction. This data may not. Wondering about your thoughts on this piece: The primary consideration when selecting an agent is often how stable the patient is (since most of these agents can cause hypotension). Thoughts ? 50-200 mcg every minute or so until you get the blood pressure above a diastolic of 60; this will temporize the situation and make the patient’s heart more likely to slow down. Click Here to Get CME Credit for the Episode. I’m now “Emeritus” (which means I’m no longer practicing) – but the dosing I used for many years when practicing (and attending) regarding use of Digoxin is as follows: – IF the patient has not previously been on the drug – consider IV loading (with 0.25-0.5 mg as the initial dose). and he was refractory to synchronized biphasic shocking. Spoon Feed Among patients with atrial fibrillation with rapid ventricular response (RVR), low-dose magnesium (4.5g over 30 minutes) was an effective adjunct to standard therapy* compared to placebo and caused far fewer side effects than high-dose magnesium. Calcium showed good effect as a pretreatment for verapamil. is easier for whom? The mechanisms underlying AF are not fully understood but it requires an initiating event (focal atrial activity / PACs) and substrate for maintenance (i.e. This Post was by the EMCrit Crew, published However, measurement of magnesium levels and repletion may be considered. Had a few crashing A-Fib pts of late. Digoxin has a long half-life (~36-48 hours, or longer in renal insufficiency). Thanks. However, among critically ill patients this has a low success rate. – May follow this with smaller IV increments (of 0.125-0.25 mg) every 2-6 hours, until a total loading dose (0f ~0.75-1.5mg) has been given over the first 24… Read more ». Don’t die in ignorance here is his contact Dr.bayoherbalkingdom @ yahoo. Ensure that the patient has been provided the full. If digoxin does fail, it may be combined with a beta-blocker or diltiazem. Morgenstern J. Unstable Atrial Fibrillation: ED Management. Published on February 12, 2010. We are the EMCrit Project, a team of independent medical bloggers and podcasters joined together by our common love of cutting-edge care, iconoclastic ramblings, and FOAM. Had this today and just wanted to thank you for this post. EMCrit 20 – The Crashing Atrial Fibrillation Patient Atrial Fibrillation is a Pain in the Butt. ⚠️ Don't conclude that amiodarone has failed to work without re-bolusing adequately. Infusion may be converted to oral administration after >24 hours. In this situation, anticoagulation may become beneficial. What dose are you giving? In this situation, it's difficult to know whether to accept atrial fibrillation or continue efforts towards conversion to normal sinus rhythm. However, it remains murky whether the NOAF. would not cardiovert, screen for dig and a/v blocking meds, […] Vidareläsning flimmer: här och här och här […]. A survey of intensivists in the UK found that most (64%) don't routinely anticoagulate patients with new-onset atrial fibrillation. Boriani G, Biffi M, Frabetti L, et al. For patients with more robust hemodynamics and lower risk of hypotension, either a beta-blocker or diltiazem may be chosen – more on this below. Generally, no more than 15 mg total will be used initially. Normally, when in AF the heart rate is limited by the refractory period of the AV node. The guideline, Pharmacologic Management of Newly Detected Atrial Fibrillation was developed by the American Academy of Family Physicians. Most of this literature isn't applicable to the general ICU population. Wide-complex beats can result from transmission over the accessory pathway. Accessed October […], Hi Scott, I have used Diltiazem for unstable AF patients in the ED setting multiple times, with great effect. The target may vary depending on patient specifics and clinical response. Preamble (Full Version) e126 2. Minor question but why do you mix the Diltiazem into 50ml? However, note that hypovolemia is relatively uncommon among patients who are admitted to ICU. This is WPW and these patients just love to ruin your day by going into v. fib. Your patient is pale and diaphoretic. a supraventricular arrhythmia that adversely affects cardiac function and increases the risk of stroke. The presence of digoxin may reduce the required dose of beta-blocker or diltiazem, thereby improving hemodynamic stability. did you hear Laura Bontempo’s cool talk also on this topic (the 2016 the crashing patient conference. (1) Discontinue beta-adrenergic vasopressors as able. There has been extensive discussion and debate about the best way to manage acute AF centered around rate and rhythm control. Risk scores for bleeding and thrombosis haven't been validated in the ICU (e.g., CHAD-VASC, HAS-BLED). Read EMCrit Podcast 20 – The Crashing Atrial Fibrillation Patient by with a free trial. Now what? not the best agent. SBP improved to 80s. 1.2. To keep this page small and fast, questions & discussion about this post can be found on another page here. Unless otherwise noted at the top of the post, the speaker(s) and related parties have no relevant financial disclosures. An ECG is a test that records the rhythm and electrical activity of your heart. Risk-Based Anticoagu Amiodarone may be utilized if magnesium infusion is ineffective. If a patient with AF and an accessory pathway is displaying instability, proceeding directly to DC cardioversion is indicated. Be careful when cardioverting patients with a heart rate <100, as there may be an increased risk of bradycardia. In Australia, instead of phenylephrine, Metaraminol (Aramine) is a more popular drug, It is a fast acting peripheral vasocontrictor, loved by most anesthetist. Atrial Fibrillation in critical illness - an IBCC chapter (by @PulmCrit & @adamdavidthomas) https://emcrit.org/pulmcrit/af/. Can you do one on all remaining tachyarrythmias! Typically, 50% of the total loading dose is given initially, followed by 25% given twice, every six hours. There is no good data regarding this, specifically: (1) There is no RCT-level evidence regarding the comparison of these agents for rate control in the ICU. Among patients with long-standing AF who have been previously on anticoagulation, this will often be continued (unless it is necessary to hold it for a procedure or bleeding). I had a similar concern about ketamine during a recent case: I had recent case of a late 40s, relatively healthy man who presented with shortness of breath. In one book of… Read more ». Additional doses may be given every 5 minutes, titrating to effect (reduction in heart rate, without causing hypotension). Rationale for magnesium in rhythm control: Among critically ill patients, magnesium seems to have similar efficacy when compared to other antiarrhythmics. Critically ill patients have numerous risk factors for bleeding (e.g., renal dysfunction, use of antiplatelet medications, invasive procedures). If you enjoyed this post, you will almost certainly enjoy our others. Load with 150 mg bolus, then infuse at 1 mg/minute. Hi Scott. US and European guidelines cite a lack of evidence for their non-promotion of it. Rapid AFib with a wide QRS over 220/minute is enough to start one thinking. 1. I thought about push dose phenyl, but second guessed myself because I didn’t want to worsen the afterload on an LVEF that was previously documented around 30%, maybe making perfusion worse. Early or Delayed Cardioversion in Recent-Onset Atrial Fibrillation. Copyright 2009-. Medicines called anti-arrhythmics can control atrial fibrillation … Yeah, yeah the Pavlovian ACLS response–You cardiovert. Prevention of Thromboembolism e130 1. The table below provides typical maintenance doses, based on the patient's renal function and body weight. For example, a multicenter RCT found that for AF following cardiac surgery, a rhythm control strategy increased the likelihood of being free from atrial fibrillation two months later (94% vs. 98%; A recent multicenter RCT among outpatients found that a rhythm-control strategy among patients with onset of AF within <1 year led to a lower risk of adverse cardiovascular outcomes. I think it is fine, the beta may increase automaticity and therefore make the a-fib harder to break but this is purely theoretical. It is sharply frowned upon to withdraw fluid from the bag before adding medications b/c it adds to complexity of mixing, leads to more likelihood of breaks in sterility, and more potential for mishaps. Amiodarone is generally a solid choice for ICU patients with the potential for hemodynamic instability (as is true for. Overall, both strategies are generally reasonable and the choice may depend on patient specifics. No RCTs have been performed comparing rate control vs. rhythm control in a general ICU population. Ooops – I meant to say Scott (Rob does the other great podcast show = ERCast)! Mortality rates of 45% vs 16% without a fib. Having new onset atrial fibrillation in critical illness increases your mortality risk from 22% to 44%. Blogspot. At the time of the podcast, it was still brand name only–which I never recommend. Atrial fibrillation is classified according to the duration of the arrhythmia. The optimal target may also vary over. If there is other evidence suggesting PE, CT angiography may be indicated. A while ago I had a 60 yr old patient with a history of MI 6 month ago with monomorphic VT 220 bpm, his SBP was around 60, he was still conscious, we cardioverted him … would you chose the same sedation/analgesia (ethomidate + ketamine) agents as you have mentioned in this podcast? Scott, […] con il monofasico. For patients without enteral access, scheduled IV doses may be required. Cardiology - Core Content & Guest Lecture. The management of atrial flutter is overall very similar to that of AF. For example: Wean off infusion over the next few hours. What are your thoughts on using an adrenaline infusion to improve the BP before infusing amiodarone? If it is unclear whether there are P waves or fibrillation waves, consider obtaining a, (One exception to these criteria is that if AF is combined with heart block, then the ventricular response may be regular.). 1.4. I’d want to see a low iCAL first. You walk into the room and see a grey, diaphoretic man, who you later find out is 67 years old. for the acute care of patients with atrial fibrillation (AF) and atrial flutter (AFL) at the University of Michigan Health System. However, the risk of stroke may relate to the. Atrial fibrillation (AF) is the most common sustained dysrhythmia and is characterised by disorganised atrial electrical activity and contraction resulting in an “irregularly irregular” ventricular response (“fibrillation waves”) AF may be acute, transient, … Yeah, yeah the Pavlovian ACLS response--You cardiovert. However, both options are entirely reasonable. However, combining ibutilide with magnesium can improve its safety and efficacy: The main side effect of ibutilide is prolongation of QTc, which cause Torsades de Pointes. Available at [https://emcrit.org/emcrit/crashing-a-fib/ ]. Read more about how atrial fibrillation is diagnosed. For most patients who aren't on medications that suppress the AV node, AF will have a heart rate of ~120-180. Medicines to control atrial fibrillation. Doing so has got to minimize the hypotensive effect. thanks for listening. Abbreviations e129 3. Thanks! If the heart rate is >>200, consider the possibility of an accessory tract (AF plus Wolff Parkinson White). increase myocardial workload. Now you need to raise the BP before anything else. Trying to “normalize” the heart rate (e.g., targeting a rate below 100) may increase the risk of iatrogenic harm in patients with tenuous hemodynamics. If possible, pretreatment or post-treatment with amiodarone +/- magnesium may enhance the likelihood of achieving and maintaining sinus rhythm. […] [Click to read more and hear the podcast] // […]. However, at heart rates below ~150, the diastolic filling may often be OK, so the dominant driver of cardiac output may be the heart rate. Scott, I’m a medic – what if I’m in the field – and cardioversion fails, and I do not have push-dose phenylephrine? Shock early, shock often, light them up. 50-200 mcg every minute or so until you get the blood pressure above a diastolic of 60; this will temporize the situation and make the patient's heart more likely to slow down. There was a small RCT in JEM 2004 that showed no difference in hypotension with Calcium vs. Hi everyone. No tachycardia, no hypertension. In surgical ICUs that’s a little worse. The combination of aggressive magnesium loading plus adequate doses of amiodarone achieved a cardioversion rate of 90% in one series of critically ill patients. Four agents are generally used for rate control: digoxin, amiodarone, beta-blockers, or diltiazem. Hi Scott An 18-year-old man with Wolff-Parkinson-White (type B) syndrome developed episodes of syncope due to atrial fibrillation. In our ambulance service we do not carry an alpha agonist but adrenaline which we can set up as an infusion usually starting at 5mcg/min. Use push-dose phenylephrine . Atrial fibrillation in the Wolff-Parkinson-White syndrome may be life-threatening because of the extremely rapid ventricular rates that can occur over the accessory pathway. 1-2 ng/mL levels may improve contractility, so these aren't unreasonable levels for closely monitored ICU patients. We recently had a patient 5 days post CABG who went into a-fib with long pauses of 7 to 8 seconds. Thanks again Just nice pain relief. See, rhythm control strategy for critically ill patients. If ineffective, the infusion may be up-titrated as follows: Up-titration may be performed about every half hour as needed (up to a maximal infusion rate of 0.2 mg/kg/min). We never spam; we hate spammers! How long would you typically observe a elderly patient after administering a 150 mg bolus of amiodrone with the drip to follow. Ibutilide may be superior to procainamide among critically ill patients, because it has greater efficacy and no negative hemodynamic effects. Im on digoxen and its not helping. Chronic lung disease 2.3. Blood pressure is 70/50. Hi Scott First 10EM. I.honestly dont know what to do. (2) There is no RCT-level evidence comparing metoprolol versus a diltiazem. Even in the studies where magnesium was less effective than an active comparator, it still demonstrated some reduction in HR. The main drawback of ibutilide is that, unlike amiodarone, ibutilide doesn't provide ongoing antiarrhythmic support to prevent AF recurrence. We have been having the same conversation about Dig on our tachy septic patients. Monitor for effect. Again, thanks to Dr. Schneider for the cardiology FOAM Calcium can sig. In a similar situation i.e. In this episode, I discuss the crashing atrial fibrillation patient. Avoid anchoring excessively on AF as the cause of the patient's hemodynamic instability. My thoughts about which part? PA is probably better than AA if you have pads. Magnesium has an excellent safety profile, with one meta-analysis detecting no reported adverse events due to magnesium within any study. emcrit.org. Proposed mechanisms include: Focal activation – In which AF originates from an area of focal activity. The first IV dose (typically ~400-600 mcg) takes effect within roughly 1-4 hours. Digoxin is the only agent which reduces heart rate while simultaneously functioning as a positive inotrope. So you folks start with the higher dose of amio right off the bat? Response to 10 mg IV –> Start metoprolol tartrate 25 mg PO q6hr. If you have a. fib with a wide QRS and a rate > 250-300, be scared, very scared. In such patients, successful management depends on treating the underlying problem. Acute atrial fibrillation is Scheuermeyer F, Pourvali R, Rowe B, et al. Esmolol compared to Amiodarone for recent-onset afib showed superiority of esmolol, IBCC Chapter on Afib with Critical Illness, http://media.blubrry.com/emcrit/p/traffic.libsyn.com/emcrit/EMCrit-Podcast-20100212-20-Afib.mp3, EMCrit 298 – Calcium in Exsanguinating Patients with Ricky Ditzel and Jeffrey Siegler, EMCrit 297 – EVARs, TEVARs, and Endoleaks – Oh My! To make the situation worse, he had infective COPD /type 2 respiratory failure with… Read more ». Overall, available evidence suggests that beta-blockers may have an edge among ICU patients. what about if not responding to inotropes ? Drip it in at 2.5 mg/minute until HR < 100 or you get to 50 mg. (Resuscitation 52:167, 2002) See here for more. Page last reviewed: 24 April 2018 Com +2349058155528 for whatsapp or visit his website Drbayoherbalkingdom . Thus, for example, causing a drop in the heart rate from 130 to 90 may often cause a. Make sure the synch is on. Re-evaluate to make sure there isn't an underlying problem (e.g. Blood pressure is 70/50. Coadministration with a magnesium infusion will, Administration of magnesium has been shown to substantially improve the. Even if the magnesium has failed to work alone, continuing the magnesium infusion may still remain beneficial in combination with amiodarone. Digoxin may be uniquely beneficial for patients with heart failure whose hemodynamics are very tenuous, who may have difficulty tolerating a negative inotrope. Start with ~150-300 mg amiodarone load and an infusion of 1 mg/min. ⚠️ If AF is being driven by another underlying process, focusing solely on suppressing the heart rate with medications will fail – and may actually make the patient worse. Can we use midazolam for sedation in the shocked patient and would it be enough for cardioverting the shocked patient?…thank alot for your kindness, norepi is currently infusion, so too slow. The cardioversion worked, but his pressure remained in the 70’s in NSR afterwards, with signs of poor perfusion. One very small RCT found that amiodarone and ibutilide were equally effective. That link isn’t working here is the correct link: http://www.medscape.com/viewarticle/810008. An interesting accompaniment of very rapid AFib with WPW is that there will often be marked variation in the length of the R-R interval (some relatively long R-R interval intermixed with much shorter ones). Thanks for the info and the comment. 1.1. If you have a. fib with a wide QRS and a rate > 250-300, be scared, very scared. as above etomidate if I have it b/c it disappears quicker, otherwise ketamine is a fine choice, Julie’s comment led me to relisten to this podcast – which gave me 2 additional thoughts I wanted to comment on re the ‘Crashing AFib Patient’: The rate of AFib doesn’t have to be 300/minute for me to begin thinking about WPW. Canadians in Ottawa demonstrated safety and efficacy quite nicely. In s … Merely trying to squash the heart rate can be dangerous among these patients, as it may suppress a. ACLS guidelines typically recommend immediate cardioversion for unstable patients with AF. However, several arguments can be made for attempting rhythm control in these patients: (#1) Most patients with NOAF will eventually revert back into sinus rhythm on their own. 1. Wonderful, except it didn't change a thing. . 1. The treatment worked incredibly for my Parkinsons disease, i have a total decline in symptoms including tremors, stiffness, slow movement and others. (1) A patient with chronic AF develops critical illness. The Canadian 2020 guidelines state that “In some cases, such as sepsis, the acute administration of intravenous anticoagulation increases the risk of bleeding, but does not appear to reduce the risk of ischemic events.”. Wide, fast, and A-Fib--give procainamide or shock them. As shown above, cardiac output is equal to heart rate multiplied by stroke volume. Consider 5-7 mg of etomidate along with a pain dose of ketamine, 10-15 mg. Respiratory failure should be aggressively treated (e.g., CPAP for heart failure, BiPAP for COPD, HFNC for pneumonia). First diagnosed atrial fibrillation: Atrial fibrillation that hos not been diagnosed before, irrespective of its duration and symptoms. with Ani Aydin, EMCrit 296 – The French Connection, Part 1 – Resuscitation Geography, Logistics, & Ergonomics, Click Here to Get CME Credit for the Episode, The Crashing Atrial Fibrillation Patient « The Central Line, Fibrillazione atriale nell'anziano instabile - EM Pills, http://www.theheart.org/columns/trials-and-fibrillations-with-dr-john-mandrola/untangling-knots-how-a-feeforservice-model-complicates-the-work-of-an-af-doctor.do, http://www.medscape.com/viewarticle/810008, Management of unstable atrial fibrillation in the emergency department | First10EM, Cardiac Emergencies 1 – North State EM Fellowship, Atrial Fibrillation • LITFL Medical Blog • CCC Cardiology, emDOCs.net – Emergency Medicine EducationUnstable Atrial Fibrillation: A Guide to Management - emDOCs.net - Emergency Medicine Education, https://emcrit.org/emcrit/crashing-a-fib/, Consider signing out to one of your colleagues and running away, This study would indicate that perhaps we are doing more harm than good when we aggressively try to control rate or rhythm in stable (non-crashing) patients (Ann Emerg Med 2015;65(5):511), Wait and See rather than rhythm restoration seems non-inferior, Write it off on your taxes or get reimbursed by your department. do you mean you can’t give CaGluconate blindly . Note that the dose of amiodarone required for. EKG shows atrial fibrillation… What are you going to do??? In light of your push dose pressers update- are you still using push dose phenylephrine for these patients, or are you now using push dose epi? I don’t use dilt drips for all of the reasons they mention. Another simpler option is to use IV metoprolol. Heart rate is 178. For us prehospital folks without access to lots of pressors…any consideration for starting a dopamine drip at alpha-dominant doses? This is a follow up post to Bryan Hayes’ summary of emergency department (ED) management of acute atrial fibrillation. I am now on the training program for Anaesthestics (Anaesthesiology) and whenever we have this scenario in the OT and I suggest IV Diltiazem the Anaesthetists (Anaesthesiologists) always look at me like I’m crazy and tell me I would cause a cardiac stand still and kill the patient (usually the patient is already on a Beta-blocker long term or they have already tried carefully titrate in some Esmolol with little effect). I just have not found them to be as effective as dilt or amio. If volume overload is present, diuresis may be beneficial. However, starting with more frequent dosing may allow more flexibility in dose adjustment. Document Review and Approval e129 4. Thank. Beta-blockers are recommended as first-line agents for rate control following cardiac surgery (a situation with some parallels to AF among other critically ill patients). Critically ill patients often have systemic inflammation, and may increase their risk for thromboembolic stroke compared to outpatients. Scott, I’d like to thank you for the great work you’re doing, I have learnt really a lot from your podcasts and some times when I’m in doubt what to do I ask myself WWWD (what would Weingart do) and it always helps. I’ll add tachy rhythms to the future show list. I ended up calling cardiology and they scratched their heads for about 30 minutes… Read more ». Answer: Atrial Fibrillation (A. fib) 1-5 Risk Factors: Increasing age, hypertension, diabetes, MI, heart failure, obesity, obstructive sleep apnea, smoking, alcohol use, hyperthyroidism, family history. I am one of these patients. Is there any harm in using procainamide as the first line antiarrythmic in this scenario? This may be useful for patients with potential hemodynamic instability, if they aren't good candidates for digitalization (see above). If the patient is chronically in atrial fib, the shock rarely works. what she called “pharmacologic enhancement”, to increase the chances that the cardioversion would… Read more ». AF diagnosis should always be confirmed with a full 12-lead EKG. Surprised Esmolol specifically not mentioned here. Adding on amiodarone is often useful here (it is more hemodynamically stable and less likely to cause synergistic hypotension in combination with other agents). Would love your thoughts, please comment. My service carries Epi and Dopamine. It was approved by the Board of Directors in April 2017. the ? What about norepinephrine which has mainly alpha stimulant effect so little change in heart rate can it be used instead of norepinephrine? Post was not sent - check your email addresses! (#3) AF may impair cardiac function in a subset of patients, due to impaired atrial kick. There is no high-quality evidence regarding the optimal approach to NOAF in the context of general critical illness (e.g., sepsis). EKG shows atrial fibrillation... What are you going to do??? I’ve tried to look at the literature myself but am… Read more ». To get to the alpha, you have already maxed out the beta, so prob. I was placed on Sinemet for 7 months and then Sifrol and Rotigotine was introduced which replaced the Sinemet but I had to stop due to side effects. Metoprolol tartrate usually isn't given every six hours. 2004 May;26(4):395-400). Calcium pretreatment clearly works for verapamil, not as clear with dilt. Por ejemplo: Si no hay Etomidato o Ketamina? The optimal heart rate for critically ill patients is unknown, but some patients may benefit from a mild compensatory tachycardia. Hypoxemia or respiratory distress may be drivers of AF. Heart rate is... Screen for WPW. 35 mg for a 70-kg patient). Therefore, steady state may not be reached until about a week after a dose adjustment. Casey. They advocated us to give 5-10cc of calcium gluconate as to offset the hypotensive effect of the drug. If bradycardia occurs, further administration should be held. What is your gen experience and take on Esmolol for the crashing A-Fib pt? Bottom Line. https://emcrit.org/emcrit/crashing-a-fib/. 4. For patients with renal insufficiency, intermittent boluses of magnesium may be utilized (targeting a level of ~3-4 mg/dL). To diagnose atrial fibrillation, your doctor may review your Now that it is generic, it is definitely an option. New-onset AF (NOAF) refers here to AF that began during hospitalization for critical illness, in a patient who previously did, NOAF correlates with worse outcomes, including mortality. Thanks so much for commenting and listening! Hi Scott! TSH should be considered if there is no obvious cause of AF, or if other clinical features suggest thyrotoxicosis. Thanks for the great podcast . For the most unstable patients (especially patients with severe systolic heart failure and longstanding AF), digoxin may be a consideration. When you're done listening to the podcast. 3) ACS with possible additional ischemia from atrial fib with RVR At very high rates, the heart rate may appear to be regular (“pseudo-regularization”). The following figure will serve as a general framework for approaching a critically ill patient with AF: The most important intervention for critically ill patients with AF is usually treating the causes of AF. When AF occurs in the context of an accessory pathway. Failure of magnesium and amiodarone to work suggests that the patient's heart doesn't want to go into a sinus rhythm (e.g., perhaps due to significant chronic atrial dilation, underlying structural heart disease, or profound systemic inflammation). In some patients, this may be a “sinus tach equivalent” which is due to an underlying problem (e.g., sepsis, PE). Digoxin is not an extremely powerful agent, so it may fail to achieve optimal heart rate control. 2004 May;26(4):395-400). When I saw him he was in sinus tach in the 110s, SBP 70s-80s. 2015; 65(5): 511-522. Julie, the rec here is for pain dose ketamine. What do you think? Though things look better, you have not really fixed the problem, you have just temporized. I heard the “gray hairs” in my dept talk about Dig, but it takes forever to kick in, right? You might as well give yourself the best chance of success, so go right for 360 J on monophasic, or equivalently high on your biphasic. This will not cause more injury than lower joules (Heart 1998, 80:3 and Resuscitation 1998;36:193). Pericarditis 2.4. When in doubt, round down. Heart rate is 178. Other considerations in selecting an agent are shown here: One of the longstanding controversies in AF management has always been selecting between metoprolol and diltiazem. Err on the lower end in patients with renal dysfunction, hypothyroidism, and/or reduced muscle mass. Anche Scott Weingart che aveva trattato questo argomento un paio di anni fa in The crashing atrail fibrillation patient, concorda nell’utilizzare le energie più elevate 360 J col monofasico , e le […], I had trouble deciding what to do recently on a patient who presented with decompensated CHF and rapid a fib. exactly right. He was in a rapid SVT (probably a fib) with a rate of 190 and systolic BP in the 60s in the field and was cardioverted without sedation to sinus rhythm. There was a recent study out of Canada promoting it, and we have a couple doctors here that seem to go after it as their first choice, and it makes me, as a pharmacist, a little uneasy. , CPAP for heart failure, BiPAP for COPD, HFNC for pneumonia ) output., hypokalemia, hypomagnesemia, ejection fraction within any study right off the bat, dexmedetomidine may a...
