I had one of those 12 LED EKGs done and the last line had a slight increase and decrease, which had some form of arrythmia on the problem part... could that be from stress? When I had the tests done I was freaking out because I had to get shots the next days, but I've realized my heart only beats weird like it was doing when I'm really nervous.. would that be a reasonable answer?

I have been told stress can cause pvc's. So can to much nicotine,electrolite imbalances, a fever, smoking and etc.......Stephanie
