More frequent post-extrasystolic potentiation in patients with premature ventricular contraction (PVC)-related cardiomyopathy – The missing link between PVC and cardiomyopathy?

Premature ventricular contractions (PVCs) are extrasystoles originating from the ventricles. PVCs are frequently observed in patients with heart diseases, who require medical treatment to resolve the underlying issues. PVCs have also been observed in people with structurally normal hearts, for whom medical treatment was deemed unnecessary. However, studies in a canine model have shown that exposing healthy hearts to frequent PVCs can cause cardiomyopathy (PVC-induced CM), evidenced by a decline in left ventricular ejection fraction (LVEF, to
