I48.0: Paroxysmal atrial fibrillation

Paroxysmal atrial fibrillation is a heart condition characterized by irregular and often rapid heart rates. Its name comes from its periodic nature, with episodes usually starting and ending abruptly, and lasting for minutes or hours before the heart reverts back to its normal rhythm. This condition may cause palpitations, a sensation of a racing heart, shortness of breath, or weakness. It occurs when the electrical signals in the heart's upper chambers, or atria, become chaotically disorganized, leading to a fast and irregular rhythm. The condition doesn't typically pose a direct and immediate life threat, but it increases the risk of ischemic stroke and can lead to other heart-related complications. The pregnancy of this condition can differ from person to person, with some patients experiencing frequent episodes while others only occasional.
