摘　　要：目的探讨二尖瓣关闭不全病人R波波峰出现时间与心功能的关系。　方法测量 33例左室射血分数 <5 0 %及 2 2例左室射血分数≥ 5 0 %对照者的最大R波波峰时间。　结果左室射血分数 <5 0 %与对照者相比平均最大R波波峰时间升高 ,P <0 .0 0 0 1。　结论证实R波波峰时间与心功能呈负相关。Objective To explore the relations between R peak time and cardiac function in patients with mitral incompetence. Methods Left ventricular ejection fraction of 33 patients (subject group) less 50% and 22 patients (control group) over 50% was given ECG to determine R peak time. Results The max average of R peak time was higher in subject group than in control group (P< 0.0001 ). Conclusion The results indicate that R peak time has negative correlation to cardiac function.
