You haven't given us anything we can relate to heart rhythm symptoms.
I believe some have temporary hair loss side effects to various medications. Are you taking any prescription medications?
From Lizzatflorida-Sorry I do take metoprolol and I had to go to the emergency room twice because I thought I was having a heart attack-The pharmacist said that one of the side affects is hair loss but I know what happens when I don't take this medicine.
I take 100 mg metoprolol and I am not aware of any hair loss from that. I've taken as much as 200 mg, but only for short periods. Not hair loss then either.
I think some side effects, like hair loss, are frequently temporary...hope that's your situation.
