premature ventricular contraction (PVC),

compression within the lower cardiac chambers; such contractions may cause perception of palpitation in patient.

premature ventricular contraction

n. Abbr. PVC
An ectopic heartbeat that originates in the ventricles of the heart and sometimes produces accompanying palpitations.

premature ventricular contraction

Ventricular premature beat Cardiology A ventricular beat initiated by an ectopic focus, which occurs before the usual sinuatrial beat, characterized by premature, widened, bizarre QRS complexes, not preceded by a P wave; PVCs are extremely common, occur in12 of normal adults monitored by EKG for 24 hrs, and are of no significance Etiology Anxiety, fever, stimulants, associated with drug toxicity–digitalis, quinidine, tricyclic antidepressants and an indication for discontinuing therapy Treatment Lidocaine, quinidine, propranolol, amiodarone
