How Fast Can The Human Heart Beat?
The human heart generally beats 60 to 80 times a minute, though anywhere between 60 and 100 beats per minute is considered normal, according to the Heart Rhythm Society. The heart beat increases during exercise, up to 160 to 180 beats per minute. Similar heart rates are common when a person is frightened or surprised, and are caused by the body’s release of adrenaline, causing the common fight-or-flight response. However, a continuously increased heart rate for no reason can be a sign of disease and should be investigated by a physician. • Tachycardia is a condition in which the heart beats faster than normal. For a doctor to diagnose tachycardia, the heart must beat at a rate of 100 beats per minute or more. This rate may vary somewhat depending on age; children generally have faster hearts than adults and the heart continues to slow down as we age. If a heartbeat is fast but also irregular, it is diagnosed as atrial fibrillation which is the most common type of heart rhythm disorder
