As I said; "mild" is the operative word here. What you have sounded like severe myocarditis.

Mild is special. It isn't nearly severe enough to warrant a surgery, and most medicine have only limited efficiency. It is just being permanently aware of your heartbeat and having the constant mental state that something is about to happen because your heart is perpetually in a state of duress. Your blood pressure is normal. Your heart rate is normal. But you'll spent every waking moment incapable of centering yourself because you feel like you are heading towards a heart attack. For the last 10 goddamned hours
