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