Insights
Premature ventricular contractions (PVCs) are common in children and usually resolve on their own. However, frequent PVCs may indicate an arrhythmia-induced cardiomyopathy requiring intervention.
Area of Science:
- Pediatric Cardiology
- Electrophysiology
- Cardiac Arrhythmias
Background:
- Premature ventricular contractions (PVCs) are frequently observed in pediatric populations.
- Most childhood PVCs are benign and self-limiting.
- Persistent or frequent PVCs can, however, be associated with cardiac pathology.
Purpose of the Study:
- To offer practical guidance for identifying potential cardiac disease in children presenting with PVCs.
- To highlight specific PVC characteristics that warrant further cardiac investigation.
- To differentiate between benign and potentially pathological PVCs in pediatric patients.
Main Methods:
- This review synthesizes current literature on pediatric PVCs and associated cardiac conditions.
- It focuses on clinical characteristics and electrocardiographic patterns of PVCs.
- Guidance is provided on when to suspect underlying cardiomyopathy.
Main Results:
- Frequent PVCs can lead to arrhythmia-induced cardiomyopathy.
- PVCs are rarely a primary manifestation of cardiomyopathy.
- Specific PVC burden and morphology may raise suspicion for cardiac disease.
Conclusions:
- Clinical vigilance for cardiac disease is essential in children with frequent or complex PVCs.
- Early recognition of PVCs indicative of potential cardiomyopathy can guide timely management.
- This review aims to improve diagnostic suspicion for cardiac pathology in pediatric PVC cases.
Abstract:
Premature ventricular contractions (PVCs) are common and generally benign in childhood and tend to resolve spontaneously in most cases. When PVCs occur frequently, an arrhythmia-induced cardiomyopathy may be present requiring medical or catheter ablation. PVCs are only rarely the manifestation of a cardiomyopathy. The purpose of this review is to provide some tips and tricks to raise the suspicion of a cardiac disease based on the presence and characteristics of PVCs in children.

The cardiac action potential process involves a series of phases characterized by the movement of ions across the cardiac cell membranes, leading to the depolarization and repolarization of the cardiac myocytes.
