my 24 your old daughter, 5 1 weighing approx. 95 pounds, said she has experienced her heart pounding very fast when she sometimes takes a hot shower. Her chest hurts. She took her pulse about 5mins. later and it was 90. She said that she had water and yogurt prior to the shower. She thinks that when she exercises her heart pounds more rapidly than her friend s hearts do. She doesn t have any medical problems except for migraines. At doctor visits where they draw blood, she is prone to passing out. Once she said she couldn t see for a few seconds after receiving a shot. She lives out of town and has a very stressful job as a teacher. She is coming home in April, should she have her heart checked out and what tests should be ordered? Thanks her mom.
