CABG, Beta Blocker Rebound and Running?

Welcome! Your being here is giving others (me 🙂 ) ideas too! When all ideas are shared, then the discussion with our doc can be much more meaningful maybe... So, my two cents: As an engineer, when troubleshooting why something is wrong, I MAKE ONE CHANGE AT A TIME. Check the results, then, if not result I wanted to see, PUT IT BACK THE WAY IT WAS and try a different change. Repeat.
I say this because you are taking more medicines than just the Lopressor; can either of the other 2 medicines for cholesterol cause your issues?
10 years ago when I started on BP medicine, I took a beta blocker. But it had to be changed to an Alpha blocker instead as it made me so dizzy I couldnt even drive... Now back to Lopressor like you and yep, dizzy, but I did get A-fib out of my aortic surgery 4 weeks ago... I wonder if there isn't a different medicine that a) reduces heart rate, b) reduces BP, and maybe helps reduce A-fib? I was on a water pill for a week after surgery; it stated it could reduce A-fib IIRC...

@yorlik Thanks for the reply. I'm also an engineer (electrical) and have been looking at data lol.
My concern was the rebound effect from stopping Lopressor suddenly, because my heart rate and blood pressure seemed to have spiked. I went back to my running logs and compared my runs' average heart rates and when I started and stopped the Lopressor. Without performing a null hypothesis test, it looks like there is a difference between before and after heart rates.
After my first posting, my cardiologist put me on a holter monitor for a weekend and I'm awaiting the results of that. The rebound effect seems to have subsided and no longer dizzy when standing, resting heart rate is normal (ca. 62 bpm), climbing stairs does not cause me to get winded, but I still do have some irregular heartbeats. My average heart rate while running is higher but perceived exertion is lower for the same running pace with and without Lopressor.
Google is a dangerous thing- you can find what you want lol... but I have seen some apparently reputable sites (mostly targeted to an athletic audience) that suggest ARB's, ACE inhibitors, or a calcium channel blocker may be viable options. Diuretics are not suggested as the can lead to easy dehydration for those who sweat a lot during workouts. By the way, sweat reduced after I stopped the Lopressor. While I was on it, after a run, it looked like I was sprayed down with a garden hose and I lost 5% of body weight in sweat, compared to ca. 2% without Lopressor.
Stay tuned for further developments. Thanks again for the reply.
