You need more research if you think you can’t get LVH from peds.I run cycle and have never touched it and my BP has never been high. We can agree to disagree. Your heart doesn't enlarge form PEDS. I could be wrong but i havent seen a study that says it. High BP can.
OP said he has genetic hypertension, so better consult your doctor and let them prescribe if you need maintenance bp meds.
I know more people now suffering because of untreated high blood pressure who thought that exercise and proper diet can cure their hypertension, these are natural individuals never touched peds at all.
