I started having pvcs in 2018 was given beta blocker and couldn't take it , gave me a Calcium channel blocker that kept them away until last year. Even after stopping the calcium blocker. Came back after getting covid and a stressful situation this year. Sometimes they catch them if I go to ER some times they don't. Its frustrating.

I have had PVCs for my entire life, the cause has never been determined. During my ablations they stimulated my heart to try to put it into vtach so they could map it and they were successful. I imagine they will do that for you as well. At the time of my surgeries I was having vtach very sporadically also.
