Can J point <0.1 mV preceding anterior T-wave inversion differentiate benign T-wave inversion from arrhythmogenic right ventricular cardiomyopathy?
J point <0.1 mV preceding anterior T-wave inversion has a limited role in differentiating normal physiological variants from ARVC.
The ECG is frequently abnormal in patients with ARVC and anterior TWI is the most common feature. Anterior TWI is usually accompanied by other abnormalities in ARVC, which are uncommon in healthy individuals. J point <0.1 mV preceding anterior TWI is not specific to ARVC and is observed in the majority of healthy individuals, including athletes, indicating a limited role for differentiating physiology or normal variants from ARVC.
Finocchiaro et al. (Sat,) studied this question.
