title: Assessment of QT dispersion as a prognostic marker for sudden death in a regional nonreferred hypertrophic cardiomyopathy cohort.
abstract: In a consecutive, prospectively assessed and unselected hypertrophic cardiomyopathy (HC) cohort closely resembling the true disease state, QTc dispersion (and QTc) on the 12-lead electrocardiogram did not prove to be a reliable predictor of HC-related sudden death. Therefore, QT dispersion would not appear to be useful in devising future risk stratification strategies for predicting sudden death in HC.
