摘要：

An interesting development in the field of heart failure has been the link between frequent premature ventricular contractions and cardiomyopathy. We report a patient whose frequent ventricular bigeminy resulted in left ventricular impairment that resolved after the use of non-contact mapping during radiofrequency ablation. A review of the literature regarding possible mechanisms is discussed. For the practicing clinician, the question of 'frequent' should be taken in context of symptoms and LV function. A single 24-h Holler monitor may not truly reflect the ectopic load. We recommend that if there is associated LV dysfunction and a causal link to frequent PVCs then suppression with radiofrequency ablation is a safe and effective treatment strategy.
