Key result
Among children with a high premature ventricular contraction burden (≥20%), 19.4% (95% CI 6.2-32.6%) met criteria for cardiomyopathy, mostly at initial presentation.

What is the prevalence of premature ventricular contraction-induced cardiomyopathy in children with frequent premature ventricular contractions?
Children with a high burden of premature ventricular contractions have a nearly 20% prevalence of PVC-induced cardiomyopathy, highlighting the need for regular imaging follow-up.
Spector et al. (2015) conducted an observational in Frequent premature ventricular contractions (n=36). High premature ventricular contraction burden (≥20%) was evaluated on Prevalence of cardiomyopathy (95% CI 6.2-32.6). Among children with a high premature ventricular contraction burden (≥20%), 19.4% (95% CI 6.2-32.6%) met criteria for cardiomyopathy, mostly at initial presentation.
