I had severe PVC's that thumped very hard, made me stop and catch my breath, and made my life miserable for the past 4 years or more.
Then 7-8 months ago, I had a PM inplant due to bradycardia. The PM became inflamed, and had to be removed, and a new one implanted on the opposite side. It too became inflamed, and removed, so I now have no PM.
The good news is, after the first implant, my PVC's lessened in frequency and severity. Instead of having say 1000+ per day, I have maybe 50.
