Assessment of the relationship between the ambulatory electrocardiography-based micro T wave alternans and the predicted risk score of sudden cardiac death at five years in patients with hypertrophic cardiomyopathy

Objective: Micro T-wave alternans (MTWA) has been associated with poor arrhythmic prognosis in various cardiac disorders. The aim of this study was to assess the relationship between the presence of MTWA and the predicted 5-year risk of sudden cardiac death (HCM Risk-SCD) among patients with hypertrophic cardiomyopathy (HCM).
