Prevalence and significance of T-wave inversions in predominantly Caucasian adolescent athletes
Key result
Lateral, inferior, or deep T-wave inversions in athletes warrant investigation for cardiomyopathy.
Why the study?
The prevalence and clinical significance of T-wave inversions in predominantly Caucasian adolescent athletes were not well characterized.

Implication
May support refined ECG thresholds in adolescent athletes; extends juvenile pattern data but leaves open prospective validation.

Prevalence and significance of T-wave inversionssurrogate
In adolescent athletes, T-wave inversions beyond V2 in those aged 16 or older, or in inferior/lateral leads, are abnormal and require further evaluation for underlying cardiomyopathy.
Cite This Study
Papadakis et al. (2009) studied this question. T-wave inversions in V1-V3 are common in athletes <16 years, but inversions beyond V2 in older adolescents, in inferior/lateral leads, or deep inversions warrant cardiomyopathy investigation.
