arrhythmia

Abnormal heart rate or rhythm: tachycardia (faster than normal heart rate) and bradycardia (slower than normal heart rate). It is caused by a disruption of the heart’s conduction system, which generates and transmits electrical impulses in the heart. It can be caused by coronary artery disease, stress, exertion, or some drugs.
