Hello sir, my name is ishaan, I am 19 years old, actually I am healthy teen, I am weighing around 100 kgs, and also my BP usually remains more than normal, I usually feel shortness of breath and yesterday I was just standing to drink water but suddenly something happened to me like it was a sudden black out in front of my eyes and it was a feeling like my heart would sink at that moment and I can't breathe at that time, I was trying to breath but it was like oxygen is not going through my body and also suddenly I was having cold sweats! And after 1 or 2 minutes everything was fine it was a feeling like I came out from unconsciousness after sitting on my chair! Can it be a MINOR HEART ATTACK? I have my ECG checked 3 years ago but it was normal, and also I feel sometimes very rare like 1 time a month a sudden pain like someone pinched me very hard near my heart and also when I wake up between my sleep at night I also hear my heart beating alot like it makes my body vibrate uh know what I meant to say !PLEASE HELP me, I will be waiting for your reply Kindly reply as soon as possible! Thanks Ishaan.
