目的:观察不同组别冠心病患者的TaTe间期和QTd之间的差异及其TaTe间期和QTd与室性心律失常相关性。方法:入选315例住院患者,入院时全部予以12导联心电图检查,经过计算机图像软件处理获得TaTe间期和QTd的资料。同时入院后予以Holter检查,将不同患者按照Holter检查结果分组,计算患者上述指标的数据与室性心律失常发生率的相关性,从而评估它们对室性心律失常的预测能力。结果:TaTe间期对复杂性室性心律失常(包括复杂性室性期前收缩、室性心动过速、心室扑动、心室颤动)有预测价值,可以为复杂性室性心律失常提供早期干预依据。而QTd对复杂性室性期前收缩没有预测价值,难以作为预测室性心律失常的量化指标。对于单纯室性期前收缩(单形、单源)频发TaTe间期无预测价值。结论:与QTd相比,TaTe间期对预测室性心律失常更有价值。
Objective: To observe the difference between TaTe interval and QTd in different groups of patients with coronary heart disease and the relationship between TaTe interval and QTd and ventricular arrhythmia. Methods: A total of 315 hospitalized patients were enrolled. All patients were admitted to the hospital with 12-lead electrocardiogram. The data of TaTe interval and QTd were obtained through computer image software. At the same time Holter examination was performed after admission, and different patients were grouped according to the Holter test results, and the correlation between the data of these indexes and the incidence of ventricular arrhythmias was calculated to evaluate their ability of predicting ventricular arrhythmia. RESULTS: The TaTe interval has predictive value for complex ventricular arrhythmias (including complex ventricular premature contraction, ventricular tachycardia, ventricular flutter, ventricular fibrillation) and may provide early intervention for complex ventricular arrhythmias in accordance with. However, QTd has no predictive value for complex ventricular premature contraction and is difficult to predict quantitative ventricular arrhythmia. For simple ventricular contraction (single, single source) frequent TaTe no predictive value. Conclusion: Compared with QTd, TaTe interval is more valuable in predicting ventricular arrhythmia.
