What is a defining feature of permanent atrial fibrillation?

Permanent atrial fibrillation is characterized by a long-term condition where the heart exhibits a continuous irregular rhythm. This form of atrial fibrillation is defined by the absence of the possibility to restore normal sinus rhythm, which distinguishes it from other types of atrial fibrillation that may be paroxysmal or persistent. In permanent atrial fibrillation, the abnormal rhythm is typically sustained, and there is a conscious decision often made in collaboration with the patient concerning the management of the condition rather than aiming to return to a normal rhythm.

This is fundamental in the management of patients, as understanding the nature of the condition informs treatment strategies which largely focus on rate control and anticoagulation to reduce the risk of stroke, rather than conversion back to sinus rhythm. This distinction is critical, as it sets the expectations for both healthcare providers and patients regarding the condition's management and long-term outcomes.
