Model I adjust for: age and sex.

Model II adjust for: age, sex, syncope, sustained ventricular tachycardia history, beta-blockers, family history of ACM, number of T wave inversion, major repolarization criterion, left ventricular ejection fraction, left ventricular end-diastolic volume index.

ACM, arrhythmogenic cardiomyopathy; LV, left ventricular; LVLD, left ventricular longitudinal dyssynchrony; GLS, global longitudinal strain; GCS, global circumferential strain.
