Hello. Thank you for your question and welcome to HCM. I understand your concern.
This ST elevation, found particularely in young people, wıth an upper slope deflection, is called early
repolarization or accelerated repolarization. No harm comes from that, it ,s a variant of normal. This can be easily mistaken by some doctors as acute myochardial
ischemia, but I, as your doctor, would tell you that there is nothing to worry about. As for the hert rate, it is considered normal from 60 - 100 beats per minute. However, in young people, highly trained athletes and vigorous physically active people, it is accepted down to 48 per minutes, referred on most studies. So, this is another thing you should now worry about. Should frequencies lower than 40 beats per minute occur, consult your cardiologist.
I hope I was helpful. Wish him a good health.
Kind regards,
Dr. Meriton
