The Prognostic Significance of Frequency and Morphology of Premature Ventricular Complexes during Ambulatory Holter Monitoring

摘要

Multiform premature ventricular complexes (PVCs) are associated with an adverse prognosis in patients with structural heart disease. Very frequent PVCs are associated with ventricular dysfunction. Our hypothesis is that multiform PVCs confer an adverse prognosis in the general population.
