I'm a 35 year old male, active, in shape, regularly go to gym, etc. No other health issues. I was sitting at my desk at work and out of the blue, my heart started 'running away'. It was if I was in the last few minutes of my regular workout at the gym after running 3 miles.

I was confused and didn't know what was going on. I felt light headed, dizzy, thought I was going to pass out, and panicky. I immediately drove to my family doctor and told him what was going on. He did an ekg in the office and said my ekg was irregular and sent me to the er. He called ahead to the cardiology department so that I wouldn't have to wait in the er. When I got there they took my straight back and did another ekg, echocardiogram, and put a 24 hour holter monitor on me. They sent me home and said the doctor would call if something was wrong.

One doctor read my echo and another read the holter results. The doctor that read the echo said everything was fine. The other said the holter showed wpw. My family doctor said he didn't think there was anything wrong and believed that my prescription of wellbutrin sr was doing it. I have been taking it since last fall, and had only recently been able to take the full does, 300mg, without having nausea. He said I was fine and not to worry.

But, the 'racing' heart feeling did subside, but, didn't go away for about a week. During the first 3 or 4 days I had a stabbing chest pain that ran down my left arm. Then the 'racing' was only 'gone' for about two days and has returned, but, barely noticible. Enough, however, to keep me out of the gym.

So, I went ahead and made an appointment with another cardiologist to get his 'formal' opinion.

Today I picked up the test results from the hospital and see the following on the echo report:
1) normal left ventricular systolic function with minimally increased thickness of the interventricular septum. Estimated ejection fraction is 60%.
2) myxomatous changes involving both the anterior and posterior mitral valve leaflet with mild mitral valve prolapse and mild mitral valve regurgitation.
3) mile tricupsid valve regurgitation with normal right-sided pressures.

This is on the holter report:
1) predominate underlying rhythm was sinus with evidence of pre-excitation in the form of wolff-parkinson-white syndrome. Minimum heart rate recorded was 44 beats per minute at 1am. Maximum heart rate recorded was 146 bpm at 1:34pm which was self limiting and well tolerated. Avg heart rate was 73. I really didn't 'do' anything while wearing the holter, but, around 12pm that day I got ready and went to the dmv and grocery store.

So, what's this mean? Anyone have any ideas?

Thanks!
