I am a 34-year-old female smoker with chest pains (exertion and at rest), palpitations, and a fast heart rate. I have no other cardiac risk factors (other than smoking), and I had a 24-hour Holter and a dual-isotope exercise stress test. The Holter monitor showed my resting heartbeat at a maximum of 168 bpm, with symptoms of chest pain and a fluttery feeling in my chest during the increased heart rate. The stress test came back positive, showing decreased blood flow into parts of my heart after exercise. Does anyone else have a similar experience? Should I still be worried? Why is the chest pain persisting if the stress test was a false positive? How reliable are they? I am having a CT angiogram, but my cardiologist is not taking this as seriously as I would like because of my age. What do you think?? The chest pains and symptoms I am having are getting increasingly worse and more frequent. I saw my cardiologist today, and he said that while my stress test came back positive and my Holter showed the abnormal heart rate, he does not think there is anything seriously wrong. He thinks the stress test might be a false positive . I am extremely worried about these chest pains and other symptoms, and I am worried that both of these test came back positive. I just wanted to add a thank you to your answers. I was so frustrated when I left the doctor s office, I can t even tell you. I am seriously concerned about these symptoms, even if they turn out to be nothing. I realize that a fast heartbeat may be controlled with medication, and if there would actually be any blockages, those could probably be controlled wiht medication, also. I just didn t feel like he was taking me seriously at all and dismissing my symptoms. I actually started to wonder tonight if it was in my head. The cardiologist was not going to leave it unchecked, but he didn t address my chest pain, and he didn t seem to take my symptoms as seriously as I thought he should have. Thank you so much for the answers. I am looking for another cardiologist tomorrow. Did I mention that he lost my echocardiogram (and never read it), and didn t give me the prescription for the Cardizem for my fast heart rate (not to mention, didn t even really address it or its cause).
