Key result
QT dispersion was significantly increased in hypertensive patients with left ventricular hypertrophy (64.0 ms) compared to hypertensive patients without left ventricular hypertrophy (49.2 ms) and healthy controls (31.9 ms).
Why the study?
Is QT dispersion increased in essential hypertensive patients with and without left ventricular hypertrophy compared to healthy controls?

QT dispersion may mark arrhythmic risk in hypertensive LVH; hypothesis-generating and should not yet change practice.

Absolute Event Rate: 64% vs 49.2%
p-value: p=<0.05
QT dispersion is significantly increased in patients with essential hypertension, particularly those with left ventricular hypertrophy, suggesting it may serve as a non-invasive marker for increased risk of ventricular arrhythmias.
Gawali et al. (2013) conducted a cross-sectional in Essential Hypertension (n=80). Hypertension with Left Ventricular Hypertrophy (LVH) vs. Hypertension without LVH and healthy controls was evaluated on QT dispersion (ms) (p=<0.05). QT dispersion was significantly increased in hypertensive patients with left ventricular hypertrophy (64.0 ms) compared to hypertensive patients without left ventricular hypertrophy (49.2 ms) and healthy controls (31.9 ms).
