摘　　要：目的现已明确冠心病患者发生猝死与恶性室性心律失常密切相关,本文旨在探讨冠心病患者Q-T间期变异性与发生室性心律失常的相关性。方法采用动态心电图分析54例冠心病室性心律失常患者24hQ-T间期变异性。结果冠心病室性心律失常患者24hQ-T间期变异性明显减低。结论冠心病室性心律失常患者24hQ-T间期变异性较正常人明显减低,其发生心律失常的可能性将明显增加。Objective The correlation in sudden death of coronary heart disease and ventricular arrhythmia is proved.To study the correlation of the patient's Q-T interval with ventricular arrhythmia.Method Using24hour ambulatory ECG to analyze54cases QT interval variability of coronary heart disease with ventricular arrhythmia.Result It is found that24hours QT interval variability is lowered obviously in patients who have coronary heart disease with ventricular arrhythmina.Conclusion The24hours QT interval variability is lower obviously in patients who have coronary heart disease with ventricular arrhythmia than normal person,the possibility of cardiac arrhythmia will be increased obviously too.[
