3 weeks ago i had a heart attack (my 3rd attack ) durring the attack i was told the dr lost me 2 times and i had to be shocked. i also was medivacd to another hospital on a helicopter, my ? is , i was experiencing cold shivers , i was so cold i was shaking like someone in a freezer. my other attacks didnt do this , this is bothering me maybe in a crazy way , but was this a symptom of heart attack , the drugs or was it just due to blood pressure being so low with them loosing me 2 times or was it due to me being so close to death?
