Abstract
Aim of the Study: The evaluation of the QT dispersion interval (QTd) alterations, in pts with essential hypertension, and furthermore, the investigation of their possible clinical significance. Methods: We included 48 outpts (23 men, 25 women), mean age 52 ± 7.5 yrs, with first diagnosed essential hypertension. All pts underwent: a) a surface 12-lead ECG (paper speed 50 mm/sec), for the calculation of QT corrected interval (QTc) according to Bazet's formula, followed by the calculation of QTd (QTcmax-QTcmin), by two independent investigators, and b) a M-Mode echocardiogram, for the definition of the presence (LVH+) or not (LVH-) of Left Ventricular Hypertrophy (LVH), defined by the Left Ventricular Mass Index, and by the relative Left Ventricular Wall Thickness. Results: According to gender, and to the presence or not of LVH, our results are presented in table 1.Conclusion: In pts with first diagnosed essential hypertension, there is a clear, direct positive relationship between QTd alterations and the presence or not of LVH. For this reason, this marker could be proved useful for the quick first estimation of the presence of LVH, in this group of pts.
