Also known as Irregular Heartbeat, Cardiac Arrhythmia, Heart Arrhythmia, Cardiac Dysrhythmia, and Abnormal Heart Rhythms
Cardiac dysrhythmia (also known as arrhythmia or irregular heartbeat) is any of a large and heterogeneous group of conditions in which there is abnormal electrical activity in the heart. The heartbeat may be too fast or too slow, and may be regular or irregular. A heart beat that is too fast is called tachycardia and a heart beat that is too slow is called bradycardia. Although many arrhythmias are not life-threatening, some can cause cardiac arrest.Source: Wikipedia
