Twinsplusone40,
Thanks for the post.
You mentioned PVCs in the title, but no where else. I'll assume that the ER physician or nurse stated that your husband had these on the monitor ...
I have not heard of low dose steroids leading to PVCs. High-dose steroids, such as that used for cancer or lupus, can lead to palpitations, so I suppose that some people might experience increased PVC/palpitations with steroids. The good news is that these should go away when the effects of the steroids wears off -- maybe 1 to 2 weeks.
I can't say that either one of these drugs is causing the palpitations, other changes in his lifestyle could be the culprit -- including lack of sleep from itching!
Hope that helps.
