【摘 要】目的：探讨心电图对高钾血症的临床诊断价值。方法：由两名心电图专业医师对48例血清钾浓度5.5～10.0mmol/L的患者进行心电图分析。结果：对血清钾浓度5.5～7.0mmol/L的患者，两名医师认定心电图有典型高钾血症改变的分别为34.6 %、42.1%；对钾浓度7.0～10.0mmol/L的患者中，两名医师认定心电图有改变的分别为90.9%、95.5%。对存在非钾离子浓度或酸碱代谢异常患者，两名医师诊断符合率分别为57.5 %、62.5%；对无非钾电解质浓度异常的患者，两名医师诊断符合率分别为75.0%、87.5%。两名医师的kappa系数为0.78。结论: 对怀疑存在高血钾症的患者，应该尽量在进行心电图检查的同时检测血清电解质，而不能仅仅依据心电图做出诊断和处理。

【Abstract】Objective: To investigate the clinical value of electrocardiogram diagnosing hyperkalemia. Methods: ECG of 48 cases with the serum K+ concentrations within 5.5～10.0mmol/L were analyzed by two doctors. Result: In the patients with serum K+ concentrations within 5.5～7.0mmol/L , coincidence rate of diagnosis were 34.6 %、42.1%. and the coincidence rate were 90.9%、95.5% in the serum K+ concentrations within 7.0～10.0mmol/L. In the patients with abnormal concentration of sodium, chlorine and other non-potassium ion., coincidence rate of diagnosis were 57.5 %、62.5%. and the coincidence rate were 75.0%、87.5% in the the patients with normal other non-potassium ion. Conclusion：The patients who were suspected with hyperkalemia, should be detected serum electrolytes as much as possible while being conducted ECG. and can not be diagnosed or treated based on ECG only.
