Question: 1 / 400

What is the distinguishing characteristic of paroxysmal atrial fibrillation?

AF that cannot be converted back to normal sinus rhythm

AF that self-terminates within a week

Paroxysmal atrial fibrillation is characterized by episodes that self-terminate, typically within a week. This means that patients experience intermittent episodes of atrial fibrillation that come and go spontaneously. These episodes may last for a few seconds to several days but usually resolve on their own without medical intervention.

The self-limiting nature of paroxysmal atrial fibrillation allows patients to return to normal sinus rhythm, which distinguishes it from other types of atrial fibrillation, such as persistent or permanent forms. Understanding this characteristic is vital in managing and treating patients, as it indicates a different approach compared to more sustained types of atrial fibrillation that may require long-term treatment strategies.
