Key result
In patients with hypertension, QTc interval was correlated with increased left ventricular mass index and systolic blood pressure.
Why the study?
In hypertension, excessive blood pressure load leads to left ventricular remodeling and QT interval alterations, but the correlation between structural changes and repolarization remains unclear.

Does QT interval correlate with left ventricular mass index and blood pressure in patients with hypertension?
Answers are grounded in this paper and cite their sources.
QT interval elongation is weakly but significantly correlated with increased left ventricular mass index and systolic blood pressure in hypertensive patients with normal geometry and concentric remodeling.
Background: In patients with hypertension, the excessive blood pressure load correlates with neurohormonalactivities and will lead to left ventricular remodeling. QT interval often occurs in patients with hypertension.The correlation between structural changes and repolarization remains unclear.Method: This study involved 62 patients with hypertension (38 female and 24 male) to whom blood pressure,electrocardiogram and echocardiography examination were performed simultaneously. The correlationbetween QT interval with left ventricle mass index and blood pressure was statistically analyzed usingPearson correlation test.Results: The mean of QTc interval in patients with hypertension was 390.40±30.73 millisecond. Based onthe echocardiography examination results, the mean of left ventricular mass index was 75.38±12.36 withRWT of 0.36±0.06. Pearson correlation statistical analysis shows a correlation between QTc interval withleft ventricular mass index (r=0.277; p value=0.030) and systolic blood pressure (r=0.317; p value=0,014).Conclusion: QT interval correlated with increased left ventricular mass index and systolic blood pressure inhypertension patients with normal geometry and concentric remodeling.

Budi Susetyo Pikir (2020) conducted a cross-sectional in Hypertension (n=62). QTc interval was evaluated on Correlation between QTc interval and left ventricular mass index (LVMI) (r=0.277, p=0.030). In patients with hypertension, QTc interval was correlated with increased left ventricular mass index and systolic blood pressure.
