So i was 20 years old, and having an episode of stress, because of some financial situations.
I took it too seriously when it wasn't, and as a result i had a stress induced cardiac arrest.
I realized my heart has stopped thumping and started hitting my chest with my fist , while calming down my thoughts at the same time. about 10 seconds of no heart beat later, the heart slowly started thumping again and in a few minutes it regained normal BPM.
I didn't tell anyone and did not go to the hospital.
Since then i started having Angina . Some days every heart beat will be a pain and my left back would go numb with needle pricking like feeling and if i exert myself , my lefty arm would go numb too.
Its been 33 years since, and i am still alive. I still do 35 minute 5k on the treadmill, and i still deadlift 90kg for 3 reps and 70Kg for 5 reps, and i still get all those pains.
I can still do 25 Push ups and 5 Pull ups, and i still do calisthenics, the easy exercises
Its just that i have got used to those pains and don't bother me .
Its just that after the treadmill session i cant feel the left side of my face ...and back......and arm...as all had gone numb.
I have had my heart checked in Pakistan as you did. Same tests and a valve was found to be malfunctioning . That was back in the 90s, a few months after the episode.
In UK i had my heart checked by the NHS. They say i have a slipping valve which causes the pains. A non return valve is allowing the blood back into the chamber it should not. They prescribed me medication which i never took, and still dont.
I just bear the pain, and i find that easier every passing year.
When i die, i will die, and that will be the end of it, but am not going to die before my death, and try my best to keep living.
