Hello!
I'm 40/m/190lbs/6'0" non-smoker, non-drinker, don't exercise, and haven't eaten very healthy over my life.
Suddenly in Jan of 2019 I started to feel faint, my heart starts beating hard and fast, cold sweat, nausea, cold shivers, slight tightness in chest, hard to breathe (like someone was sitting on my chest.) and extreme exhaustion.
Rushed to the ER, taken in as a heart attack, verified it was not a heart attack. After a couple hours felt better and was sent home.
