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.
T-wave inversions in V1-V3 are relatively common in athletes or=16 years, T-wave inversions in the inferior/lateral leads and deep T-wave inversions in any lead are unusual, warranting further investigations for underlying cardiomyopathy.
Papadakis et al. (Sat,) studied this question.
