Frequent Premature Ventricular Contractions as a Modulator of Ventricular Mechanics: Evidence from Modern Echocardiographic Modalities

Background: Premature ventricular contractions (PVCs) are commonly encountered in clinical cardiology and have traditionally been viewed as a benign finding in the absence of structural heart disease. Increasing clinical experience and imaging data, however, indicate that a high burden of PVCs may influence ventricular mechanics and contribute to both subtle and overt myocardial dysfunction. This review aims to examine the impact of frequent PVCs on ventricular mechanical performance, with particular emphasis on the role of modern echocardiographic techniques in detecting early functional impairment beyond conventional measurements.Conclusion: Frequent PVCs may induce alterations in ventricular contraction and relaxation that are not reliably captured by standard echocardiographic parameters such as ejection fraction. Advanced echocardiographic modalities, including tissue Doppler imaging and speckle tracking–derived strain analysis, enable earlier identification of subclinical ventricular dysfunction. Incorporating these techniques into routine evaluation may improve risk stratification, guide therapeutic decisions, and help prevent progression to the PVC-related cardiomyopathy.
