Atrial Fibrillation

Professor Lori Daniels

Atrial fibrillation, or "A-fib,” is the most common heart-rhythm issue, characterized by a problem with electrical signals that control the heartbeat. A-fib results in failure of the upper chambers of the heart (the atria) to beat in a rhythmic fashion. It can last from a few seconds to many years and can occur as the result of numerous concomitant illnesses or normal aging. A-fib may be highly symptomatic, with a racing heart, chest discomfort, shortness of breath, lightheadedness, and fatigue, or it may be totally asymptomatic. Regardless of whether it causes symptoms, A-fib can lead to stroke, heart failure, and other serious problems if it is untreated.
