Atrial fibrillation is associated with an increased risk of heart failure, dementia, and stroke. [3] [12] It is a type of supraventricular tachycardia. [14] Atrial fibrillation frequently results from bursts of tachycardia that originate in muscle bundles extending from the atrium to the pulmonary veins. [15]
A normal resting heart rate is 60 to 100 beats per minute. A resting heart rate of more than 100 beats per minute is defined as a tachycardia. During an episode of SVT, the heart beats about 150 to 220 times per minute. [9] Specific treatment depends on the type of SVT [5] and can include medications, medical procedures, or surgery. [5]
Put down the holiday drink and take care of the heart with new guidelines on Afib. ... Cases of atrial fibrillation, the most common form of a heart arrhythmia, tick up during the holiday season.
Although this abnormal heart rhythm typically occurs in individuals with cardiovascular disease (e.g., high blood pressure, coronary artery disease, and cardiomyopathy) and diabetes mellitus, it may occur spontaneously in people with otherwise normal hearts. It is typically not a stable rhythm and often degenerates into atrial fibrillation (AF ...
Atrioventricular reentrant tachycardia (AVRT), or atrioventricular reciprocating tachycardia, is a type of heart arrhythmia with an abnormally fast rhythm (tachycardia); it is classified as a type of supraventricular tachycardia (SVT).
Potassium supplementation only at levels below 3.6 mEq/L may help prevent atrial fibrillation (AFib) after heart surgery, a new study suggests. ... Atrial fibrillation is the most common clinical ...

The majority of time symptomatic WPW fits the definition of AVRT (Supraventricular tachycardia) however AVNRT (dual AV nodal physiology) exist in ~10% of patients with WPW syndrome creating the possibility of spontaneous atrial fibrillation degenerating into ventricular fibrillation (VF). The fact that WPW patients are young and do not have ...
