You also have the option to opt-out of these cookies. [6] Those with an irregular heartbeat are often treated with blood thinners to reduce the risk of complications. What areas of clinical research and innovation are Stanford doctors currently pursuing? We also use third-party cookies that help us analyze and understand how you use this website. Defibrillation differs in that the shock is not synchronised. Problems with the electrical pathway of the heart can cause very fast or even deadly arrhythmias. These contractions and relaxations occur due to electrical impulses sent by the heart muscles.

SADS may occur from other causes. [3] Supraventricular tachycardias include atrial fibrillation, atrial flutter and paroxysmal supraventricular tachycardia. Fibrillation can affect the atrium (atrial fibrillation) or the ventricle (ventricular fibrillation): ventricular fibrillation is imminently life-threatening. Please call +1 650-723-8561 or email IMS@stanfordhealthcare.org to get started. Wolff–Parkinson–White syndrome is due to an extra pathway in the heart that is made up of electrical muscle tissue. Arrhythmia may be classified by rate (tachycardia, bradycardia), mechanism (automaticity, re-entry, triggered) or duration (isolated premature beats; couplets; runs, that is 3 or more beats; non-sustained= less than 30 seconds or sustained= over 30 seconds). When they turn into a regular occurrence, it leads to life-threatening conditions. Some arrhythmias promote blood clotting within the heart, and increase risk of embolus and stroke. Our skilled electrophysiologists provide exceptional care with a compassionate touch for people with all types of arrhythmias. Valet and self-parking options are available for a fee. However, some asymptomatic arrhythmias are associated with adverse events. Get the Android MyHealth app ». If an arrhythmia results in a heartbeat that is too fast, too slow or too weak to supply the body's needs, this manifests as a lower blood pressure and may cause lightheadedness or dizziness, or syncope (fainting).[16]. The patient may complain of palpitations, dizziness, or syncope. We are pioneering hybrid surgical-catheter ablation, a minimally invasive procedure that treats your heart on both the inner and outer surface. Learn more about our exceptional care for all types of arrhythmias at the Stanford Cardiac Arrhythmia Service. Any rhythm beyond these limits is abnormal, and classed as a fetal arrhythmia. [4] In Europe and North America, as of 2014, atrial fibrillation affects about 2% to 3% of the population. [2] Treatments may include medications, medical procedures such as inserting a pacemaker and surgery. [2][3] Others may result in sudden death. This is referred to as sinoatrial block typically manifesting with various degrees and patterns of sinus bradycardia. Our arrhythmia program is one of few in the country offering advanced ablation techniques for ventricular arrhythmias. This may cause a single premature beat now and then, or, if the ectopic focus fires more often than the sinoatrial node, it can produce a sustained abnormal rhythm. II. For after-hours, reach the on-call arrhythmia doctor at 650-723-7111. The lack of oxygen can cause sudden fainting. This may be the result of medication, caffeine, nicotine, altered sodium or potassium levels in the blood, as well as cardiac conditions like scarring of heart muscles, cardiomyopathy, myocarditis, valvular heart disease, and congenital heart diseases. This can slow down or stop a number of arrhythmias that originate above or at the AV node (see main article: supraventricular tachycardias). Learn more about our support services ». We discuss all treatment options with you to decide on a customized treatment plan. This procedure may be completely curative for some forms of arrhythmia, but for others, the success rate remains disappointing. [6] Pacemakers are often used for slow heart rates. The heart pumps blood by contraction and relaxation of its four chambers. Stanford doctors and surgeons were in the first FDA clinical trial to test, Report or results from a physical examination, A form of payment for any co-pays or deductibles, You can call our Patient Billing Customer Service Office. Our arrhythmia team has specialized expertise in treating ventricular arrhythmias, the most dangerous type of abnormal heart rhythms. However, it is best to work with your doctor to decide the right care approach for your needs.
