T波电交替对复杂性室性心律失常的预测价值

Predict value of T wave alternans for complex ventricular arrythmia

目的探讨T波电交替对预测复杂性室性心律失常的价值。方法对照分析20例T波电交替患者与20例正常人的动态心电图复杂性室性心律失常发生情况。结果T波电交替组15例75%)出现复杂性室性心律失常,2例死亡;对照组3例出现复杂性室性心律失常(15%)无死亡;两组差异有非常显著性意义(P<0.01)。结论T波电交替对预测严重室性心律失常有重要价值。

Objective To investigate value of T wave alternans (TWA) to complex ventricular arrhythmias. Methods 20 mormal cases and 20 consecutive TWA cases were analyzed to see if complex ventricular arrhythmia happen by ambulatory electrocardiography. Results In TWA group, complex ventricular arrhythmias were present in 15 cases (75%),death in 2 patients. In control group, complex ventricular arrhythmias were present in 3 cases(15%),no death. Conclusion TWA is a significant predictor for complex ventricular arrhythmias.
