The ECG is abnormal in most patients with arrhythmogenic right ventricular dysplasia (ARVD). Right
ventricular parietal block, reduced QRS amplitude, epsilon wave, T wave inversion in V1-3 and ventricular tachycardia in
the morphology of left bundle branch block are the characteristic changes that reflect the underlying genetic
predetermined pathology and pathoelectrophysiology. Recognizing the characteristic ECG changes in ARVD will be of
help in making a correct diagnosis of this rare disease.
