目的探讨心电图检测对诊断高钾血症的临床价值.方法对72例高钾血症患者的心电图与血清钾浓度进行对比分析.结果心电图诊断高钾血症41例,与血清钾测定的符合率为56.9%;血清钾大于5.5 mmol/L时,心电图诊断高钾血症的符合率为22.2%,主要表现为T波高耸,里帐篷状;血清钾大于6.7 mmol/L时,心电图诊断高钾血症的符合率为74.3%,主要表现为ST段压低,P波振幅降低,时限增宽,部分患者出现窦.室传导,个别出现恶性室性心律失常;血清钾大于10.0 mmol/L时,心电图诊断高钾血症的符合率为100%,大部分患者表现为恶性室性心律失常.结论心电图表现与血清钾测定有较好的一致性,当合并其他电解质失衡时,会加重心电图的异常程度;心电图可准确、简便鉴别假性高血钾.

Objective To research clinical significance of electrocardiogram(ECG) measuring in diagnosis of hyperkalemia. Methods ECG changes and serum potassium concentration from 72 cases have been analyzed and contrasted. Results Forty-one cases with hyperkalemia are detected by ECG changes. Coincidence rate is up to 56.9% with serum potassium test. When the serum potassium concentration exceeds 5.5mmol/L, the accuracy of ECG in diagnosis of hyperkalemia was 22.2%. The main features arc peaked T wave with tabernacle shape ;when the serum potassium concentration exceeds 6.7mmol/L, the accuracy of ECG in diagnosis of hyperkalemia was 74.3%. The main features are ST debased,P wave with low amplitude and time limit increased. Some patients appeared sinus node-ventride conduction. One or two appeared malignant ventricular arrbythmia; when the serum potassium concentration exceeds 10.0mmol/L,the accuracy of ECG was 100% ,most patients appeared malignant ventricular. Conclusion The electrocardiogram measurement has the better consistency with serum potassium test, and abnormal electrocardio-gram will be eccurred,when mixed other electrolyte unbalance. Pseudo-hyperkalemia can be distinguished accurately and conveniently by using this method.
