Under quiet conditions, the normal adult one-minute heartbeat is 60~100 times, athletes are about 50 times/min, newborns are 90~160 times/min, the number of heartbeats is also related to sports, emotions and other factors. To determine how many normal one-minute heartbeats, can not be generalized, need to be based on the actual situation. For adults, the normal one-minute heartbeat is 60 to 100 beats, and the ideal heartbeat is 55 to 70 beats per minute. In the case of athletes, the heartbeat is slower than that of a normal adult, and a heartbeat of around 50 beats per minute is normal. Secondly, for newborns, the normal heartbeat is 90 to 160 beats per minute. In addition to this, the speed of the heartbeat is also related to some extent to physiological factors such as strenuous exercise, mood swings, eating, and staying up late. If an adult’s heartbeat is less than 60 beats per minute, consider bradycardia; if it is more than 100 beats per minute, consider tachycardia. If an abnormal heartbeat is accompanied by symptoms such as significant chest tightness and palpitations (rapid heartbeat, often accompanied by panic), then timely hospitalization is required.
