ABSTRACT

Objectives: In this study, we aimed to investigate the value of the frontal QRS-T angle (f(QRS-T)) in determining blood pressure control among newly diagnosed hypertensive patients with no left ventricular hypertrophy.

Methods: Fifty patients with newly diagnosed hypertension were included in this single-center study. The patients were examined with 12-lead ECGs and 24-hour ambulatory blood pressure monitoring (24 h-ABPM) before and 1 month after antihypertensive treatment.

Results: Baseline and post-treatment f(QRS-T) angle values were observed to be similar (38.0 [0.0–174.0] and 37.0 [1.0–139.0], respectively; p = .827). The values of QT minimum (p = .006), QTc mean (p = .030), Tp-e (p = .027), and JTc (p = .010) significantly decreased after control of blood pressure.

Conclusions: The f(QRS-T) angle, which can be easily calculated on the ECG, is not a useful tool to determine hypertension control at early stage in newly diagnosed hypertensive patients.

摘要

目的：在这项研究中，我们旨在研究额叶QRS-T角（f（QRS-T））在确定无左心室肥厚的新诊断高血压患者的血压控制中的价值。

方法：该单中心研究纳入了50名新诊断为高血压的患者。在降压治疗之前和之后1个月对患者进行12导联心电图和24小时动态血压监测（24 h-ABPM）检查。

结果：基线和治疗后的f（QRS-T）角度值相似（分别为38.0 [0.0–174.0]和37.0 [1.0–139.0]；p = .827）。控制血压后，QT最小值（p = .006），QTc平均值（p = .030），Tp-e（p = .027）和JTc（p = .010）的值显着降低。

结论：可以在心电图上轻松计算的f（QRS-T）角不是确定新诊断的高血压患者早期控制高血压的有用工具。
