The ideal heart rate is between 55-70 beats per minute. A heart rate of 58 beats per minute is normal and does not require special treatment. The normal human heart rate in a quiet state is 60-100 beats per minute, but there will be differences depending on age, gender and physiological factors. Generally, the younger the person is, the faster the heart rate is. It is normal for the elderly to have a slower heart rate than younger people, and for women to have a faster heart rate than men of the same age. If the heart rate is consistently below 54 beats per minute, combined with dizziness and faintness, an ambulatory ECG evaluation is required. If the heart rate continues to slow down below 35 beats per minute, consider implanting a permanent pacemaker, otherwise the slow heart rate is life-threatening.
