Sometimes PVCs can be caused by certain medications. After
taking Nexium for five years, I suddenly developed over 8000 PVCs a day. I struggled
with those for almost two years. When I tapered off the Nexium meds and used a simple, over-the-counter antacid (containing calcium and magnesium) as needed, the PVCs lessened. When I ate carefully and finally stopped Nexium completely (using the OTC antacid only when needed and in small amounts) the PVCs went away completely.
