Update: Just came back from the doctor...he'd put me on a treadmill with all kind of wires connected to my chest...and here we go....he forced me to run to my capacity limit of 176 bpm....99.68 % and all was normal from my heart pump. He told me that the problem was overtraining i.e. too much time passed at 80 to 90 % of max capacity. I'm a bit less scared now.....He told me I'm going to die one day, but not from heart problems....!
