The standard heart rate for a normal person is 60-100 beats per minute, and fluctuations within this range are normal. However, it must be measured in a quiet resting state for more than 10 minutes, measured in a resting state, which is the most accurate. If you exercise, this value is certainly inaccurate, people exercise, in the state of sympathetic excitation, measuring the heart rate, is certainly on the fast side. If the heart rate is less than 60 beats/minute, it is bradycardia, if the heart rate is more than 100 beats/minute, it is tachycardia. But from a cardiologist’s point of view, from clinical observation, it is generally believed that a heart rate of about 55 beats per minute is the best heart rate. As long as the heart rate is not lower than 50 beats per minute, it is generally not a big problem, and you should pay attention to rest and control the risk factors of rapid heart rate.
