What happens when a person's heart rate reaches 38

If there are no symptoms such as palpitation, shortness of breath and chest tightness at ordinary times, it is estimated that there are two possibilities:

First, the side effects caused by long-term use of antihypertensive drugs: Many antihypertensive drugs also have the effect of lowering the heart rate, and long-term use of such drugs will also lead to a gradual decrease in the heart rate. If this is the case, it can be improved by stopping using antihypertensive drugs. As for the choice of other antihypertensive drugs to continue to treat hypertension, please go to the hospital for a detailed examination and follow the doctor's advice.

The second is normal: there are few people with big hearts, which is very common among people engaged in mountaineering and diving. Because the pumping function of big heart is much stronger than that of ordinary people, the heart rate of such people is very low when they are calm, but it can reach 280 beats/minute or even higher when they exercise vigorously. When people with big hearts go to the hospital for physical examination, they often make jokes about arranging hospitalization because of their low heart rate and meeting inexperienced young doctors.

I suggest you go to the cardiovascular department of the local regular hospital for a detailed examination as soon as possible.
