高钾血症心电图分析

Electrocardiogram Analysis on Hyperkalemia

目的：探讨心电图诊断对高钾血症的临床应用价值。方法：分析10例高钾血症的．12,电图表现。结果：正常血钾浓度为3．5～5．5mmol／L，当血钾浓度〉5．5mmol／L时，心电图出现帐篷样高尖T波，两支对称，ORS波群增宽畸形，不定位心室内传导阻滞，QT间期延长，窦性P波消失，窦室传导，P—R间期延长，R—R间期相对匀齐，心动过速酷似房室交接区心动过速或室性心动过速。结沦：心电图同时出现高尖T波，不定型室内束支传导阻滞，P波消失，窦室传导，结合临床可高度提示高钾血症。

Objective： To explore clinical value of ECG in diagnose of hyperkalemia. Methods：ECG was analyzed in 10 patients with hyperkalemia. Rusults：The normal kalium concentration was 3.5 45.5 mmol/L. When K＋ concentration elevated ）5.5 mmol/L,ECG showed shape of tent appears high T wave, two were symmetrical,QRS complex wave increased the wide deformlty,unstable intraventricular block, Q-T interval prolong, sino P wave disappeared, sino-ventricular conduction,P-R interval was prolong, R-Rinterval was nent torelatively spare, Tachycardia bear a strong resemblance to junctionaltachycardia or ventricular tachycardia. Conclusion： ECG shows high wave of sharp T, unstable intra-ventricular black,P wave disappear, sino-ventricular conduction. The combination is dinical but the altitude prompt hyperkalemia.
