RESUMEN
Patients with arrhythmogenic right ventricular cardiomyopathy have Ventricular Tachycardia [VT] and left bundle branch block contours with right-axis deviation and T-waves inversion in pericardial leads. Presenting case was a 28 years old man admitted with palpitation and syncope. The electrocardiography showed Ventricular tachycardia with left bundle branch block contour and T wave inversions in V[1] to V[6] and incomplete right bundle branch block and T wave inversions in V[1] to V[3]. Echocardiography revealed right ventricular [RV] dilatation. RV function was abnormal, and aneurismal formation in free wall was seen in 3D echocardiography. Arrhythmogenic right ventricular cardiomyopathy remains as a primary diagnoses, in case of patients with ventricular tachycardia, left bundle branch block contour and T waves inversion in pericardial leads and without any history of ischemic heart disease
