摘要
目的探讨低钾血症与心电图改变之间的关系。方法随机选择患者并按年龄分为三组,每组以血钾为标准划分为四个亚组。统计出异常心电指标的出现频率及占比;并对中重度低钾患者进行补钾后复查心电图。结果正常亚组、轻度低钾亚组、中度低钾亚组、重度低钾亚组的平均阳性率在17-40岁年龄段分别为4.32%、15.97%、11.11%、44.44%,在40岁以上年龄段的平均阳性率分别为16.07%、20.42%、26.00%、58.33%。结论心电异常指标阳性率随血钾降低而升高,在同等缺钾状态下高龄组阳性率高于低龄组,补钾反应低龄组要好于高龄组,心电图不仅有助于对低钾血症本身的诊断,亦有助于对低钾血症继发的严重异位心律失常的及时处理。
Objective To investigate the correlation of hypokalemia and the electrocardiogram change. Methods The patients were randomly divided into three age groups and each group was subdivided into four subgroups according to potassium level. The frequency and proportion of abnormal electrocardiogram indexes in each subgroups was calculated,the ECG was checked again after potassium supplementation for moderate and severe hypokalemic patients. Results The average positive rate of normal subgroup, mild hypokalemia subgroup, moderate hypokalemia subgroup, severe hypokalemia subgroup was 4. 32%,15. 97%,11. 11%,44. 44% in patients aged 17 to 40,and was 16. 07%,20. 42%,26. 00%,58. 33% in patients over the age of forty. Conclusion The proportion of abnormal electrocardiogram indexes increase with serum potassium level decreasing.The positive rate of aged group is higher than that of young group under the same condition,effect of potassium application in young group is better than aged group. Electrocardiogram not only contribute to the diagnosis of hypokalemia,but also contribute to the timely treatment of severe ectopic arrhythmia secondary to hypokalemia.
