No, PVCS do not cause muscles in other parts of your body to twitch/spasm... but low potassium can make PVCS worse and cause a bit of muscle twitching.
A PVC may cause palpitations or a “flutter-like” feeling in the chest. If PVC’s occur frequently enough, they can cause a drop in blood pressure and/or even cause fainting. You may want to contact your cardiologist or primary-care provider regarding your symptoms so proper diagnostic studies and treatments can be performed.
