目的探讨心电图对诊断高血钾的临床价值。方法回顾性分析我院2009年10月~2012年10月在急诊抢救高血钾患者32例的心电图资料。结果经过心电图诊断与血清钾检测，32例高血钾患者中有19例心电图诊断与血清钾测定相符，急慢性肾功能不全尿毒症为主要病因，准确率达59.4%；电图诊断与血清钾测定不相符的有13例，占40.6%。急性心肌梗死为主要病因。结论心电图对高血钾改变比血清钾测定更具有临床价值，是一种简单、快速诊断高血钾的重要方法。“,”Objective Electrocardiogram (ecg) in the diagnosis of high potassium discussed the clinical value. Methods October 2009 were reviewed retrospectively Month to October 2012 in emergency rescue high potassium patients 32 cases of ecg data. Results After electrocardiogram diagnosis and serum potassium detection, 32 cases in patients with high potassium in 19 patients electrocardiogram diagnosis and serum potassium determination conform to, acute or chronic renal insuf iciency uremia as the main etiology, 59.4% accuracy; Electric diagram diagnosis and determination of serum potassium is not consistent with 13 cases, accounting for 40.6%, Acute myocardial infarction (mi) as the main cause. Conclusion Electrocardiogram (ecg) of high potassium change than serum potassium measurement is more clinical value, is a kind of simple and rapid diagnosis high potassium important method.
