I just took an EKG to allow me to participate in a local firefighting mentoring program. The doc said I had abnormalities when he looked at my EKG. Do you all think it might be caused by ephedrine i was taking? I was taking 2 a day along with 200mg of caffine for the past five weeks and stopped yesterday to help me get cut for the beach. If I would of known i was getting an EKG i would of never of taken the epherdrine. PLEASE ADVISE.
