Metoprolol 100mg. I've had Afib since 2002. An ablation in 2011. Sotalol was my go-to until I needed a liver transplant in late 2021. That didn't play well with other liver medications and went off it for a few years prior to transplant. I had to go to ER/ICU two (2) times last year for a "Class II" myocardial infarction; a heart attack not caused by a clot. I was already on metoprolol the first episode at 25mg; ICU upped to 100mg and that brought BP and pulse to normal. They bounce at ~175/110, pulse ~ 140-160 without this drug and the fib.
