I was on toprol for alittle while,
and it did help me. I was also on
Sotalol for a few years (combined with Cardizem)
and that helped me also. In regard to V-fib and sotalol, I really haven't heard of that. I have heard of v-tach a very low possibality when on sotalol, but not v-fib. I would recommend you trying the sotalol. When I was first put on it, I was monitored in the hospital for 3 days. I had no reaction to it. Yes, it did make me tired, but I got use to it. Good Luck!
