Ventricular Repolarization Abnormalities in Pediatric Athletes: A Practical Approach to Clinical Evaluation

Area of Science:

• Cardiology
• Sports Medicine
• Pediatrics

Background:

• Ventricular repolarization abnormalities are common in pediatric athletes during cardiovascular screening.
• Their clinical significance is often uncertain, with some being benign training adaptations and others indicating underlying cardiac disease.

Purpose of the Study:

• To provide a framework for evaluating ventricular repolarization abnormalities in pediatric athletes.
• To differentiate physiological adaptations from pathological conditions to prevent sudden cardiac events and unnecessary sports restrictions.

Main Methods:

• Integration of current international electrocardiographic criteria with recent pediatric evidence.
• Development of a clinically oriented approach for evaluation and risk stratification.
• Emphasis on a structured, risk-based strategy incorporating clinical, familial, and imaging data.

Main Results:

• Early repolarization and anterior T-wave inversion are typically benign in the absence of concerning symptoms or history.
• Lateral/inferolateral T-wave inversion, atypical ST-segment changes, arrhythmias, and abnormal imaging are red flags.
• Longitudinal reassessment is vital due to electrophysiological changes during adolescence.

Conclusions:

• A comprehensive, risk-based approach is essential for accurate diagnosis and management.
• This strategy optimizes risk detection while supporting appropriate athletic participation for young athletes.
• Distinguishing benign from pathological repolarization patterns is key to athlete well-being and performance.
