you would be best asking in the doctor forum as we arent doctor, im seem to see a lot of people posting ecg results, can i just ask did the doctor not explain anything to you because my doctor had to see the results before i went home, if you do the stress test and you pass you'll be fine, some meds that are used to treat arryhtmias can set off other arrthymias and tend to be dangerous, id stick with aspirin to prevent blood clots
