I have just completed 1.1 around km run in very hot climate, temp around 44. My echo tmt are normal. Cholesterol is also under control. Only issue now a days I'm feeling is skipped beats specially when i lay down. I have gastric issue too. I just want you to guide me is heart okay or shall i investigate further because i have taken numbers of test since past 6 months. 3 times echo and tmt each. Echo is normal with lvef 60. Tmt also negative. But i feel pressure in my chest sometimes and skipped beats. Is it fatal. I have very negative thoughts in mind. I think this will kill me.
