@mmst4 Hello, I was diagnosed with an incomplete RBBB. I’m a healthy 72 year old female and have had PVC’s since I was in my 30’s. No other heart issues. Was on Atenolol for a long time until the PVC’s became more frequent. I was switched to Dilitiazem 120 mg daily which didn’t help much. My cardiologist added Metroprolol 25 mg daily. I was hesitant to take it, but I’ve been taking it a few weeks and I believe it’s helping and so far no side effects. I still get PVC’s but not as many. I’m not saying that Metroprolol will work for you, but I wanted to give you my input and I hope it helps.
