Key result
Hypertension is linked to ~71% higher odds of prolonged QTc versus normotension.
Why the study?
The study was conducted to characterize the independent association of blood pressure with heart rate-corrected QT interval after adjusting for cardiovascular confounding factors and left ventricular mass in a large general Chinese population.
Is hypertension independently associated with prolonged QTc interval in a general adult population?
Cross-Sectional (n=10,553)
Is hypertension independently associated with prolonged QTc interval in a general adult population?
Effect estimate: OR 1.71
p-value: p=<0.001
Hypertension is independently associated with a prolonged QTc interval, even after adjusting for left ventricular mass and other cardiovascular risk factors.

Hypertension was associated with prolonged QTc independent of LV mass; hypothesis-generating for arrhythmia risk in cross-sectional data.
Sun et al. (2019) conducted a cross-sectional in Hypertension (n=10,553). Hypertension vs. Normotension was evaluated on Prolonged QTc interval (OR 1.71, p=<0.001). Hypertension was independently associated with a prolonged QTc interval compared to normotension, adjusting for confounding factors and left ventricular mass (OR 1.71; P<0.001).
