I was taking Amiodarone at the hospital, then at home, and all it did was turn my intestinal contents to concrete. It did nothing about my heart rhythm.
An electrocardiologist changed me to Verapamil. A hospitalist prescribed another Calcium Channel blocker (Sotolol), and my Cardiologist wanted me to continue with Benazapril. The combination dropped my heart rate into the 30s, and I felt weak and, basically, like I was dying. I went back to the hospital, feeling extremely weak, and after a day off of most medications, started to feel much better.
I went home, with instructions to only take Verapamil if my pulse was over 50. I didn't take it for three days, because my resting pulse was under 50. At the end of the third day, my pulse varied from 40 to 70 in a few seconds. I skipped the benaxzepril, took Verapamil, and put up with a heart beat of around 132 BPM. After an hour or so, the Verapamil settled things down.
I think I may have figured it out -- the Benazapril dropped my heart rate below 50 - so I couldn't take Verapamil (which improves my heart rhythm). I'm taking a half dose of Benazapril and, so far, the resting heart rate is around 53. I may discontinue Benazapril altogether and see if my heart rate goes a bit higher. It would be nice if the cardiologist and the electrophysiologist communicate better with each other.
I'll update this if things change again.
