A resting heart rate of 46 beats per minute is not normal, and the normal range of heart rate is usually 60 to 100 beats per minute. Resting heart rate is the number of heartbeats per minute when the human body is in a quiet and awake state, generally in the normal range of 60~100 beats/min. However, there may be individual differences due to gender, age or other physiological factors. Generally, the heart rate of the elderly is slower, while that of children is faster. A resting heart rate of 46 beats/minute is abnormal and is considered bradycardia. Low heart rates are normal in people who have been exercising for a long time, such as military personnel and athletes. Bradycardia can also be caused by arrhythmias, cardiomyopathy, heart failure, hypothyroidism, and other diseases. When the resting heart rate is found to be 46 beats per minute, you should go to the hospital in time for further diagnosis under the guidance of your doctor, and if it is caused by a disease, it should be treated in time.
