目的探讨Q-T离散度与原发性高血压左心室肥厚的关系。方法高血压患者40例,分为高血压病左心室肥厚组20例,高血压非左心室肥厚组20例,健康正常组20例,用全自动十二导联心电图测定其Q-T离散度数值,急性心律失常发生率。结果高血压左心室肥厚组Q-T间期测量值为56.3±9.2,急性心律失常发生率64%,而高血压非左心室肥厚组Q-T测量值为30.4±7.5,急性心律失常发生率23%,将康对照组,Q-T测量值30.4±6.8,机型心律失常发生率23%。结论血压升高不会影响Q-T离散度,只有合并左心室肥厚,才影响Q-T离散度,使其增大,且心律失常发生率亦明显增加,呈正相关,Q-T离散度可作为检测心脏事件的无创性有价值的指标。
Objective To investigate the relationship between Q-T dispersion and left ventricular hypertrophy in patients with essential hypertension. Methods Forty patients with hypertension were divided into hypertensive left ventricular hypertrophy group (n = 20), hypertensive non-left ventricular hypertrophy group (n = 20) and healthy control group (n = 20) Acute arrhythmia incidence. Results The QT interval was 56.3 ± 9.2 and the incidence of acute arrhythmia was 64% in hypertensive left ventricular hypertrophy group, while QT was 30.4 ± 7.5 and 23% in non-hypertensive patients with left ventricular hypertrophy. Kang control group, QT measured 30.4 ± 6.8, the incidence of arrhythmia 23%. Conclusions High blood pressure does not affect the QT dispersion. Only with left ventricular hypertrophy, it affects the QT dispersion, increases it, and the incidence of arrhythmia also increases significantly, which is positively correlated. QT dispersion can be used as a noninvasive measure of cardiac events Sexual value indicators.
