I was diagnosed with ascending aorta dilation in 2016, I was 25 years old then, the symptoms that made me pay close attention to it and go to do an echocardiogram were strong tachycardia at rest up to 120 beats / min, before that I had slightly elevated blood pressure 130/90 and at that time it reached 150/100. In general, as a treatment, I was prescribed a beta blocker, the dilation of the ascending aorta root was approximately in the range from 37 to 45 mm, depending on which doctor I do it with, blood pressure and pulse, not to jinx it, seem to be normal. So I decided to go and start working out in the gym with the aim of gaining muscle mass, my arms are very thin like a girl or boy of 12 years old and after the first lesson I realized that it is not for nothing that doctors recommend not to lift and carry weights, I don’t know about others but it seems to me that absolutely any exercise on the simulators if you try to do it to your limit there is a very strong tension in the heart and this is not good. If anyone knows if there is a method for gaining muscle mass without bringing strength exercises on the simulators to the limit of your capabilities or without this the muscles will not grow at all. And I would also like to ask this question in the future if I manage to do freediving, how dangerous and harmful is it in my case. Before this problem in 2013 I independently tried to do dynamics in length in bi-lasts and the maximum that I could do was 50 meters but this was without insurance after.
