Good morning all. After just over 4 months of NSR unfortunately last Fri I developed some sort of Arrhythmia and my heart is at 120 BPM. I got to see my EP last week and he has scheduled me for another ablation to "tidy up" the bits they couldn't quite finish last time and put me on Bisopralol 1.25 once a day just to lower the rate a bit. Now my question is, does the Bisopralol cause the tiredness or the effect of the Bisopralol, ie the lowered HR? I say lowered but it's still in the high 90's.
