t do a thing to my heart rate while I am in afib or flutter (though the beta blocker does reduce my resting heart rate when not in tachycardia, the Ca blocker not so much.) But the beta blocker
does seem to reduce the length of the episodes compared to
how long they last if I just let it go, so this seems to be some sort of rhythm control. (And again, the Ca blocker does not seem to be effective at this either, which is why it is a former medication.
