Hey Outlaw.... You are experiencing real symptoms, it took a long time for me to accept palpatations, fast heart etc... were symptoms that were real but were being caused by my anxiety.. I thought sure something was wrong. Have you had a Thalium (I think that is how they spell it) Stress test. They inject a radio active dye and scan your heart resting. Then they wait a couple of hours and you come back and do a stress test, they inject another tracer and you get a scan again. This way they can interpret is there are any blood flow problems. It will most likely be negative as mine was... I continued you to have heart palps once in awhile which were really annoying. My Doctor put me on 25 MG of Atenalol everyday, I may get a wierd one once in awhile but this beta blocker has really helped me. I don't have the speeding heart or the annoying pre ventrical contractions. Maybe once in awhile. THis has lessened my anxiety about something being wrong with my heart. I used to check my blood pressure and monitor my pulse all the time.. until I took that test and he gave me atenalol. The thing is Your heart is the strongest muscle in your body, it won't explode.. I have had heart rates as high as 200 and I am 46 years old..It was scary, but it showed me just how tough your heart his.. If your doctors are confident, then try to ... and I know it is hard accept what they are saying... Ask for a thalium stress test... Yes it is possible that they missed something, but it is also possible that you will be hit by a big bus crossing the street. It is hard to accept them as being right when you feel so ****py, but part of feeling better will come , it takes time. If you try to accept ok my heart is beating @100 bpm, and not let it frighten you, you will soon find that in time your heart will return to what you consider a more favorable resting heart rate. During the height of my anxiety, i feared getting out of bed to go to the bathroom because my heart was racing. Some meds also have side effects of racing heart. BUt 100 Beats per min.. even though it is not a favorable resting rate, won't kill you.... Accept it... I know it is hard, but that is the way it is with us worriers. You will soon start feeling better when you don't allow the feelings to frighte
