Greetings. Welcome to HCM and thank you for your question. I understand your concern. My answering message will be pretty much reassuring. The normal heart rate, standardized for the worldwide population is 60-100 beats per minute. It is acceptable as normal down to 45 beats per minute, and it mostly applies to young ages, highly trained athletes and people with constant moderate to vigorous physical activity. Therefore, my opinion is that there is nothing to worry about. This is also a common finding in sportsmen and sportswomen, or athletes, even twenty or more years after they have discontinued the training. Another positive thing is that even with this heart rate, you do not feel or describe any symptoms at all, let alone any dizziness or loss of equilibrium. I hope I was helpful. Take care. My regards, Dr. Meriton
