Rapid pulse Overview

A rapid pulse or “tachycardia” is an abnormality of heartbeat. An increase in the pulse is normal under various circumstances, such as exercise or anxiety, but is otherwise abnormal. There are various causes of tachycardia include heart disorders, arrhythmias, metabolic imbalances, hormonal disorders, and other causes. The opposite symptom is slow pulse (bradycardia), and similar symptoms include bounding pulse and other heart rhythm symptoms. Many of the causes of tachycardia are a medical emergency (e.g. heart attack, shock, many others) and immediate medical care should be sought for any such symptom.
