Premature ventricular complexes in children with structurally normal hearts: clinical review and recommendations for...

Area of Science:

• Pediatric Cardiology
• Electrophysiology
• Clinical Recommendations

Background:

• Premature ventricular complexes (PVCs) in children are a frequent clinical concern, yet literature is limited, often based on case reports.
• Existing studies suggest PVCs in pediatric populations typically follow a benign course and frequently resolve during childhood.
• Unanswered questions persist regarding the optimal management and long-term implications of pediatric PVCs.

Purpose of the Study:

• To provide clear, concise recommendations for the diagnostic work-up of healthy children with simple PVCs.
• To outline an appropriate clinical and therapeutic approach for pediatric patients experiencing PVCs.
• To address physician debates and family concerns surrounding PVCs in children.

Main Methods:

• Review of existing literature on isolated PVCs in children.
• Synthesis of current knowledge to formulate diagnostic and therapeutic guidelines.
• Focus on two critical actions: ruling out structural heart disease and assessing PVC-related symptoms or dysfunction.

Main Results:

• Established literature indicates a generally benign prognosis for PVCs in children, with frequent spontaneous resolution.
• The diagnostic approach should prioritize excluding underlying structural heart disease.
• Evaluation must differentiate symptoms caused by PVCs from those potentially leading to left ventricular dysfunction due to high PVC burden.

Conclusions:

• Recommendations are provided for the diagnostic evaluation of healthy children with simple PVCs.
• Guidance is offered on the clinical management and therapeutic strategies for pediatric PVCs.
• The approach emphasizes identifying and addressing potential cardiac abnormalities or functional impairments.
