I am a 29yr old male, Since 2005 I Have had symptoms when preforming cardio related activities, I have never had angina, but would sometimes feel dizzy, and sometimes feel sick to my stomach. I had a nuclear stress test in 2005, and the doctor only did a stress portion. He then told me that everything was fine. Earlier this year I had a syncopal episode after working out and then when I woke up my hear was racing. In 2005 the doctors put me on a Toporl 100mg and last year they had to increase this to 200mg. After the syncopal episode I was reffered to several doctors including a cardiologist different from the 2005 doc. I then learned that all nuclear stress tests are done with a resting and a stress portion. Low and behold I have some Ischemia in the bottom of my heart and the new Doctor has ordered a Cardiac Cath. I am overweight, but have not had hyperlipidemia untill the last two years. What are the chances that this current stress test is a false positive. And what shoud I think abou the first Doctor?
