So I've been up and down for the past few months, having palpitations and zoning out. I often feel like I will pass out or something.
I've noticed that my heart flutters when I'm excited, angry , exercising and randomly. I had ecgs, xray,echo, had my heart listened to, and 2 holter monitors, as well as all kinds of blood tests and all of that in the past 6 months.
Can it be my heart? Or is there something else I can look into?
