极化液对不稳定心绞痛患者QT间期离散度的影响

The effect of polarized liquid on QT dispersion in patients with unstable angina pectoris

目的探讨极化液对不稳定心绞痛患者QT间期离散度(QTd)及校正QT间期离散度(QTcd)的影响。方法采取随机单盲方法,将65例不稳定心绞痛患者随机分为极化液治疗组与常规治疗组,治疗两周后测定两组的QTd及QTcd,对两组进行对照分析。结果治疗组QTd及QTcd治疗分别为41.61±13.01与48.35±15.56,常规组分别为52.68±20.31与60.59±7.35,两组差别有统计学意义(P<0.05)。结论极化液治疗能减少不稳定心绞痛患者的QTd及QTcd,从而可能减少恶性心律失常的发生。

Objective： To investigate the effect of polarized liquid on QT dispersion in patients with unstable angina pectori. Methods： One hundred and sixty-fiveunstable angina patients were randomly divided into polarized liquid group and routine group. After 2 weeks＇ treatment, QTd and QTcd of two groups were measured, and the results were compared. Results： The QTd and QTcd differences between two groups were remarkable （50.61 ± 14.01vs 60.68± 17.31, 52.35 ± 15.56 vs 65.59± 14.35） . Conclusion： The polarized liquid treatment can reduce QTd and QTcd of unstable angina pectoris, and polarized liquid may reduce the occurrence of malignant arrhythmia.
