I have experienced PVC's for two decades. They are essentially harmless, but frustrating. I have been cardioverted twice, but cardioversion has fallen out of grace with recent research. A person does not stay cardioverterted very long, and the procedure is not without its risks. I still have PVC's. So, get good medical advise from various professional sources before doing anything. I have just learned to live with PVC's. They are most troublesome for me if I am stressed.
The best to you.
Have you tried a cardioversion?
