目的探讨肾功能衰竭患者的心电图特征和产生原因,及其与临床的关系。方法回顾分析165例肾功能衰竭患者常规12导联心电图。结果其中136例出现不同程度的心电图改变。心电图正常者死亡1例,心电图异常者死亡16例,两者比较有统计学意义(p<0.05)。肾功能衰竭血钾正常与高血钾的严重心律失常发生率有统计学差异(p<0.05)。结论肾功能衰竭病情变化与心电图改变有较为密切的关系,心电图改变可作为指导治疗和判断肾功能衰竭预后的一个指标。
Objective To investigate the characteristics of electrocardiogram (ECG) and its causes in patients with renal failure and its relationship with clinic. Methods Retrospective analysis of 165 cases of renal failure in patients with conventional 12-lead ECG. Results of 136 cases showed varying degrees of ECG changes. 1 patient died of normal ECG, 16 patients died of abnormal electrocardiogram, the two were statistically significant (p <0.05). There was a statistically significant difference in the incidence of severe arrhythmia between normal serum potassium and hyperkalemia in patients with renal failure (p <0.05). Conclusion The changes of renal failure are closely related to the changes of ECG. ECG changes can be used as an index to guide the treatment and judge the prognosis of renal failure.
