So I've been getting bouts of having a super low heart rate. I can feel it coming on. My head starts to hurt, my chest feels tight and I can feel every slow bump of my heart. I've gone to the ER and they said it was a migraine(which I get all the time) . I'm no doctor, but when you're in intense pain or scared, doesn't your heart rate go UP? I'm both in pain-my head really hurts, and anxious- why's my heart not beating... Anyone else have this happen? I usually run at 110-120 for my "normal" heart rate. Was on metropolol (however you spell it ) for about a year and a half but it didn't do a darn thing but make me feel like I didn't have the energy to even sleep, so they just took me off it. What the heck is happening?
