Explanation

An increase in frequency of PVCs may initiate life-threatening arrhythmias which include ventricular tachycardia, ventricular fibrillation, and other rhythms. More than 6 PVCs in a minute is serious. Increasing fluids and providing oxygen will not reduce the number of PVCs. Propofol is not indicated as a treatment for PVC.
