风心瓣膜替换术后血清钾与室性心律异常的临床研究

CLINICAL INVESTIGATION OF VENTRICULAR ARRHYTHMIA AND SERUM POTASSIUM AFTER VR IN RHD PATIENTS

目的 探讨血清钾与室性心律异常的相互关系。方法 随机选择 1 0 0例风湿性心脏瓣膜置换病人分别于术后 4 8小时内随时记录室性心律异常发生情况。包括室性早搏、室性二联律、三联律、室性心动过速和室颤 ,定时检测血清钾 ,分析对比血清钾高低与室性心律异常的相对关系。结果 血清钾 <3.5mmol/L组室性心律异常者为 80 % ,室性心律异常的发生率随血清钾浓度的增高而降低 ,血清钾 >4 .5mmol/L组仅为 6.8% ,两组相比有非常显著性差异 ,P <0 .0 0 1。结论 血清钾低是引起风湿性心脏瓣膜替换术后室性心律异常的最主要因素 ,及时补足钾 ,提高血清钾浓度能有效地防治低钾、室性心律异常。

Objective: To investigate the relationship between the serum potassium and ventricular arrhythmia. Methods: The incidence of ventricular arrhythmia, including ventricular premature beats, bigenimy beat, trigenimy beat, ventricular tachycardia,ventricular fibrillation was recorded within 48 hours after VR operation in 100 RHD patients. And the relationship of serum potassium and ventricular arrhythmia was recorded and examined. Results: The incidence of ventricular arrhythmia was 80.0%,when potassium concentration was <3.5mmol/L; and 6.8%, when potassium concentration was>4.5mmol/L. There was extremely significant difference in potassium concentration, P<0.001. Conclusion: The level of serum potassium concentration was the main factor of ventricular arrythmia after VR operation in RHD patients. To supple ment the potassium in time could prevent and treat low serum potassium and ventricular arrhythmia.
