Adjusting Optimal Heart Rate for Aerobic Exercise While On Beta Blockers?

I have been a member of these forums for quite some time and know it is not a place to ask for medical advice but I haven't been able to find much research on this, and my cardiologoist hasn't been much help either.

I take 25 mg of Toprol XL to control SVT (undetermined trigger, does not appear to be exercise induced since I passed a series of stress test without any episodes) with no other cardiac conditions, and I was wondering if I should adjust my target heart rate for aerobic exercise because of my medication, or I should just use a standard calculation of optimal heart rate for someone my age with regard to aerobic exercise? My normal heart rate w/o the beta blocker is around 89, with the beta blockers it's about 54.

Any links to reputable website or information is appreciated. Thanks.

I know nothing about this, however I always thought the whole point about taking Beta Blockers for your condition is so that you can't get your heart rate up to optimal while exercising. I would ask your cardiologist about this. I am curious about the answer for my own learning.

Please post the answer.

I can't help on the specifics, but I had an attending who advised her beta-blocker patients to use respiratory rate as their "new" aerobic exercise intensity parameter--given that their heart rate would no longer accurately reflect intensity levels.

So I should aim for the "Max Resp. Rate" that still allows me to carry on a normal conversation?

Yeah, that's what she was advising her patients to do.
