I had an ekg, and the doctor said the results warranted a stress test to make sure there were no blockages. It isn't scheduled for 3 weeks. If there is a problem, shouldn't it be done sooner? I went to the doctor because I've had a sensation of a racing heart that I think I can link to caffeine consumption, and some "skipped" beats. He said this could be normal, but because of my ekg, I should have a stress test and ultrasound. I also am going through menopause and wonder if that has anything to do with it.
