Can my replacement pacemaker be causing more frequent PVC's.


PVCs and New Pacemakers

It's hard to see how a pacemaker--old or new--could cause PVCS. A PVC is a contraction of the ventricles that happens just a little bit before it's supposed to. A PVC is a contraction that the heart does on it's own.

If the pacemaker were fautly and contrating the ventricles too early, causing the PVCs, every beat would have a PVC. If that was happening,you wouldn't wonder if the pacemaker was at fault. You would know it for sure.

But there can be no doubt that some hearts are more irritable than others. More succeptible to arrythmias from many causes. In my case, everything from lack of sleep, to emotional upset, to certain asthma medications can set off PVCs--I'm sure getting a new pacer would result in more PVCs, at least for a while. And it's possible that your heart is not reacting well to some of the settings on your new pacer, and some tweaking is needed.

I find it easy to believe that you are having more PVCS since getting the new device, and hard to believe that the new pacer is causing them. But you might need an adjustment of your settings to see if the PVCs can be minimized. Check with your doctor.

Interesting topic.  I had my PM replaced last Nov 2018.  Things have changed. Following back to back bouts with diverticulitis, C-Diff, then a pneumonia,  a PM "optimization" was performed.  LVEF was claimed to have risen from around 20% to greater than 35%.  Result: Less stamina (previous exercise was 4-5 miles daily, now 3 miles daily)  Many more PVC's.
