More recently I was given Diltiazem, still a calcium channel blocker, and
other than the usual adjustment period with fatigue and
headaches, it was fine. My doctor gave it to me for my tachycardia, not my run of the mill PVC's and PAC's. They're not considered a problem other than the heart hiccup sensation. I average 1-5 a minute.
All you can do is try the medication, see if it helps, if the side effects are worth the slight decrease in PVC's. I doubt that they'll go away completely.
