Which classification of atrial fibrillation (AF) is characterized by self-terminating episodes lasting less than 7 days?

The classification of atrial fibrillation known as paroxysmal AF is characterized by episodes that occur intermittently and self-terminate within a short duration, specifically less than 7 days. Patients may experience episodes of AF that can last from just a few seconds to a week, and they typically return to normal sinus rhythm without the need for medical intervention. This classification is vital in understanding the nature of AF in a patient, as it influences treatment decisions and the overall management approach.

In contrast, persistent AF is defined by episodes that last longer than 7 days and may require medical intervention, either pharmacological or electrical, to restore normal rhythm. Permanent AF, on the other hand, indicates a condition where AF is continuous and doesn't revert to sinus rhythm, often leading to a more chronic management strategy. First Diagnosed AF refers to the initial identification of AF but does not inherently define the self-terminating nature of episodes. Understanding these distinctions is crucial for diagnosing and treating various forms of atrial fibrillation effectively.
