12-Lead electrocardiogram of 19-year old female with advanced ARVC. Note normal sinus rhythm with frequent premature ventricular complexes with superior axis morphology, voltage criteria for right atrial enlargement, borderline prolonged QRS duration (QRS 0.10s) with fractionated upstroke in V1-3 (“terminal activation duration” >55 ms), and negative T-waves in V1-6 and inferior leads. This patient would fulfill 1 major (T-wave inversion V1–V3 and beyond) and 1 minor criterion (prolonged terminal activation duration) for ARVC. ECG settings: 25 mm/mV; 10 mm/mV; 150 Hz.
