The normal range for an adult's resting heart rate is 60 to 100 beats per minute. This range is accepted by health professionals as normal because it indicates the heart's efficiency and rhythm. Factors such as age, fitness level, medications, and overall health can influence an individual's resting heart rate, but typically, a heartbeat within this range is considered healthy and indicates that the cardiovascular system is functioning well.
A heart rate below 60 beats per minute may be normal for some well-conditioned athletes, but it can also indicate bradycardia if associated with symptoms. Conversely, a heart rate above 100 beats per minute at rest, known as tachycardia, can be a cause for concern and may indicate underlying health issues. A resting heart rate outside the normal range warrants further evaluation to assess an individual’s cardiovascular health and overall well-being.
