Exercise-induced normalization of right precordial negative T waves in arrhythmogenic right ventricular cardiomyopathy.

Negative T waves (NTWs) in right precordial leads (V₁ to V₃) may be observed on the electrocardiogram (ECG) of healthy subjects but can also represent the hallmark of an underlying arrhythmogenic right ventricular cardiomyopathy (ARVC). It has been a consistent observation that NTWs usually become upright with exercise in healthy subjects without underlying heart disease. No systematic study has evaluated exercise-induced changes of NTWs in ARVC.
