Hello doctor, My father has a slow heart rate of 52 times / minute, so please advise me on how to treat bradycardia and how to eat it. Thank you doctor.

Hello doctor, I play sports normally, my heart rate is 44 beats/min. When you sleep, you often have to lean to the right to sleep easily. The doctor asked me if my heart rate of 44 beats / min is dangerous? I thank you.
