心电图与血钾测定在显示低钾上的不一致性尚多见。其准确率目前尚未报道。我们结合临床资料对51例低钾患者作了比较分析,指出心电图比血钾测定能较准确反映患者机体真正缺钾的变化,而生化检查报告血钾的浓度,仅从数值上判断机体是否缺钾,有一定误差。 51例低钾住院患者分别作心电图检查与血清钾测定,心电图提示低钾47例,其中的30例心电图检查与血钾测定均提示低钾。心
Electrocardiogram and serum potassium in the display of inconsistency is still more common on low potassium. Its accuracy has not been reported yet. We combined clinical data of 51 cases of hypokalemia patients were compared, pointed out that ECG more accurate than the potassium test to reflect the body’s true potassium deficiency changes in patients with biochemical tests report the concentration of potassium, only to determine whether the body from the numerical lack Potassium, there is a certain error. Fifty-one hospitalized patients with hypokalemia were examined by electrocardiogram and serum potassium respectively. 47 cases showed hypokalemia by electrocardiogram, among which 30 cases showed hypokalemia by electrocardiogram and blood potassium test. heart
