Although premature ventricular contractions (PVCs)are frequently present after myocardial infarction, they are not always benign.In individuals with underlying heart disease, PVCs or episodes of self-terminating ventricular tachycardia (VT)are potentially malignant.Nonsustained VT is defined as three or more consecutive premature ventricular beats at a rate faster than 110 beats/min lasting less than 30 seconds.The patient does not appear symptomatic from the PVCs at this time; therefore, lidocaine is not indicated.Cardizem is not prescribed for ventricular ectopy.
