Does QT dispersion correlate with echocardiographic left ventricular hypertrophy in untreated patients with essential hypertension?
QT dispersion correlates with left ventricular mass index and systolic blood pressure in essential hypertension, suggesting its potential as a simple screening tool for sudden death risk even without ECG LVH.
Clarkson et al. (1995) conducted a cross-sectional in Essential hypertension (n=69). QT dispersion was evaluated on Relationship between QT dispersion and office systolic blood pressure, and left ventricular mass index. QT dispersion demonstrated significant relationships with office systolic blood pressure and left ventricular mass index in untreated patients with essential hypertension.
