Key result
Characteristic ARVD ECG features include epsilon waves, V1-3 T wave inversions, and LBBB-morphology ventricular tachycardia.
Why the study?
What are the characteristic electrocardiographic manifestations of arrhythmogenic right ventricular dysplasia?
What are the characteristic electrocardiographic manifestations of arrhythmogenic right ventricular dysplasia?
Recognizing characteristic ECG changes such as epsilon waves and T wave inversions in V1-3 aids in the correct diagnosis of arrhythmogenic right ventricular dysplasia.
ECG features may prompt ARVD evaluation; leaves open need for prospective validation against modern imaging and genetics.
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.

Zhang et al. (2014) conducted a review in Arrhythmogenic right ventricular dysplasia (ARVD). Characteristic ECG changes in ARVD include right ventricular parietal block, reduced QRS amplitude, epsilon wave, T wave inversion in V1-3, and ventricular tachycardia with LBBB morphology.
