测定34例Ⅰ期高血压病(EH)、46例高血压左心室肥厚(LVH)患者的QT间期离散度(QTd)的变化,并与30例健康人对比。结果:健康对照组QTd为(24±19)ms,Ⅰ期EH组QTd为(35±17)ms,两者差异有显著性(P<0.05),EH合并LVH组QTd为(76±24)ms,与对照组和Ⅰ期EH组的差异均有显著性(P均<0.05)。提示:合并LVH的EH患者心肌细胞存在严重复极不一致;Ⅰ期EH者仍有发生室性心律失常的相对危险性。
The changes of QTd in 34 patients with stage I hypertension (EH) and 46 patients with hypertensive left ventricular hypertrophy (LVH) were measured and compared with 30 healthy controls. Results: The QTd of healthy control group was (24 ± 19) ms, the QTd of stage Ⅰ EH group was (35 ± 17) ms, the difference was significant (P <0.05) 24) ms, there were significant differences between the control group and the stage Ⅰ EH group (all P <0.05). Hint: EH patients with LVH have severe repolarization of cardiomyocytes inconsistent; stage I EH still have the relative risk of occurrence of ventricular arrhythmia.
