My son, clean and healthy 27 year old recently went to the hospital ICU for his heart It was racing, about 170 beats a minute. They had to shock his heart back into rhythm. Since then, he has felt headaches, dizziness, arm tingling and generally not good health. He s about 6 2 and weighs a healthy 170 175 lbs. No drugs, no alcohol and no smoking. He is seeing his PCP tomorrow and he said he doesn t feel it s his heart. WHen they checked him at the hospital, no blood clots, EKG was good, Echocardiogram all good. Chest xray good. Help!
