Beta Blockers and passing out after exertion

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).

Please. Contact your doctor immediately if you are blacking out.

Contact your cardio as soon as possible. You may be experiencing a rythm disturbance causing this or could be a number of cardiac issues or not.

Agree, you should talk to your doctor, specifically a cardiologist or vascular doc.  It could be medication related or not.

I have a tunneled section with a blockage in my LAD and I pass out with heavy exercise (I experience a very forceful beat most of the time).

Good luck!

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!
