| 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＜50％及22例左室射血分数≥50％对照者的最大R波波峰时间。结果 左室射血分数＜50％与对照者相比平均最大R波波峰时间升高，P＜0．0001。结论 证实R波波峰时间与心功能量负相关。

| Abstract: | 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. |
