My daughter is 19 years old. About six months ago, she developed severe chest pain with palpitations. She was admitted to the hospital. Her heart rate remained between 130 and 160 for four days. She had a normal echo, normal EKGs and normal lab results. She was sent home on Toprol and has continued to have a rapid heart rate in the 90s to low 100s with activity. She also continues to have chest pain. She has been told it is stress, but she says she does not feel stressed. We had a stress test done and are waiting on the results, but she says the doctor who performed the test told her she was not active enough. She is a non-smoker, non drinker, no caffenine, young woman. She had no health issues before this. Published: September 11 ::
