Hi there. I am a 38 year old male, diag. with myocardial bridging of the LAD. I was prescribed beta blockers for relief of the symptoms (angina, forceful heartbeat). The bb's have helped alot, but when I do strenuous physical exercise, I tend to feel very light headed and have actually passed out, very briefly, one time. Can bb's cause this, or should I consider looking at some other heart related issue? I take a low dose (25mg Toprol XL).
I'm much older than you, but I have had multiple heart attacks and multiple stents, still work out daily swimming, light weights with high reps, and aerobic machine work. It always takes awhile after an event, but I can regain strength and endurance over time. I've passed out four times during exercise. In EACH case it was when Beta Blocker dosages were increased. I know from talking to younger gymrats they hate beta blockers as they inhibit workout performances. I'm not a health professional, but I'm guessing that you are experiencing a serious side effect from good medications. I'd strongly urge you to contact your doctor. My guess is that the dosage will be reduced. Good luck, stay active!
