Got the results back, echo was normal. 24hr holter was interesting, says my average HR was 79 BPM, minimum was 45 BPM (sleeping) and max HR was 188 BPM, which according to the time, i think was during ........ squats?! thats interesting cos i went for a run in the evening and i expected my HR to peak then, my watch reported around 175 from memory.
I think this means daily squatting isn't healthy. I prob wont continue this once i've reached my goal.
