Also known as Pulse too fast, Rapid heartbeat, Heart is racing, and Tachycardia
Tachycardia is a heart rate that exceeds the normal range. A resting heart rate over 100 beats per minute is generally accepted as tachycardia. Tachycardia can be caused by various factors which often are benign. However, tachycardia can be dangerous depending on the speed and type of rhythm. Note that if it is pathological, a tachycardia is more correctly defined as a tachyarrhythmia.Source: Wikipedia
