I48: Atrial fibrillation and flutter
I48.1: Persistent atrial fibrillation
Persistent atrial fibrillation is a condition that occurs when the upper chambers of the heart, known as the atria, beat irregularly and at a rapid pace. This condition is chronic, meaning that it persists over a prolonged period of time. Instead of the heart's rhythm being coordinated and regular, in persistent atrial fibrillation, the atria quiver rapidly and irregularly. This can cause palpitations, which are sensations of a rapid, fluttering heartbeat. Other symptoms may include fatigue, weakness, lightheadedness, confusion, shortness of breath, and chest pain. Persistent atrial fibrillation can also lead to more serious complications such as heart failure or stroke, because the irregular heartbeat can allow blood to pool and form clots. This is a common type of arrhythmia, especially in older adults.
