I'm a 21 year old female and have been having heart palpitations for the past 6 months or so, sometimes accompanied by chest tightness/aches or lightheadedness.
I don't smoke or drink. As a long distance runner, I also run about 50 miles a week (to be soon increased as I am training for a marathon), but usually my palpitations arise when i'm at rest. Also, I have been on birth control for several years and know that there exists side effects that can include heart attack and stroke.
I have noticed that the palpitations come and go. For example, i'll feel them several times a minute for two straight weeks, then the next week I don't feel them nearly as much. I'm worried sick that i'm just going to drop dead from a heart attack or something.
I've been to the md, who ran an ekg (of course, the palpitations didn't occur when the test was run). He also prescribed me something that he described as similar to a high dose of naproxem sodium. This did not seem to help. Does anyone have any suggestions or similar experiences?
