what is the average heart rate of a healthy person
Heart rate Many texts cite the normal resting adult human heart rate as ranging from 60–100 bpm.[1] Tachycardia is a fast heart rate, defined as above 100 bpm at rest.[2] Bradycardia is a slow heart rate, defined as below 60 bpm at rest. Several studies, as well as expert consensus indicates that the normal resting adult heart rate is probably closer to a range between 50 and 90 bpm.[3][4][5][6] During sleep a slow heartbeat with rates around 40–50 bpm is common and is considered normal. When the heart is not beating in a regular pattern, this is referred to as an arrhythmia. Abnormalities of heart rate sometimes indicate disease.[7]
