Arrhythmogenic right ventricular cardiomyopathy characterized by recurrent syncope during exercise: A case report

Figure 1 Twelve-lead electrocardiogram findings at admission and after drug cardioversion. A: An electrocardiogram at admission revealed ventricular tachycardia (192 beats per minute) with a superior axis (positive QRS in lead aVL and negative QRS in leads II, III, and aVF), indicating an origin in the inferior wall of the right ventricle; B: An electrocardiogram after drug cardioversion showed a regular sinus rhythm at 65 beats per minute with negative T waves and a delayed S-wave upstroke (60 ms) from leads V1 to V4.
