May signal arrhythmic vulnerability in HCM; hypothesis-generating for QTc-guided risk stratification.
Do patients with hypertrophic cardiomyopathy have prolonged QTc and increased QTc dispersion compared to normal subjects?
Patients with hypertrophic cardiomyopathy exhibit prolonged QTc and increased QTc dispersion, which correlates with left ventricular hypertrophy and may predispose them to ventricular arrhythmias.
Dritsas et al. (1992) studied this question.
