An arrhythmia is an abnormal heart rhythm that can cause the heart to beat too fast, too slow or irregularly. The heart, at its simplest, is a pump made up of muscle tissue, beating in a steady rhythm of about 60 to 100 times each minute.

An occasional heart palpitation or fluttering is usually not serious. But a persistent abnormal heart rhythm can be disabling, with symptoms such as fainting, or even life threatening in the case of a sudden cardiac arrest.

Arrhythmias are often categorized by where they originate. Atrial arrhythmias affect the two upper chambers of the heart. Ventricular arrhythmias affect the two lower chambers.

The most common type of arrhythmia is called atrial fibrillation (AFib), in which electrical signals in the heart’s two upper chambers fire too quickly and irregularly.
