本文分析了46例小儿低钾血症与心电图改变的关系,其结果由重度营养不良并重度腹泻引起低钾血症心电图改变阳性率最高,重度营养不良占第二位,重度腹泻阳性率最低。显示急性失钾和慢性失钾对血钾比值影响不同,其心电图改变阳性率有显著性差别。同时阐明钾离子对心肌细胞电生理作用和小儿低钾血症时心电图特征性改变。证实了小儿低钾血症程度与临床表现、心电图改变三者相互之间的线性关系。找出小儿低钾血症心电图阴性改变原因,提出小儿低钾血症时行血生化检查和心电图描记的评价。
This article analyzes 46 cases of hypokalemia in children with changes in the relationship between ECG, the results of severe malnutrition and severe diarrhea caused by hypokalemia electrocardiogram positive rate of the highest, severe malnutrition accounted for second place, the lowest positive rate of severe diarrhea. Shows that acute and chronic loss of potassium loss of potassium on the ratio of different effects, the positive rate of ECG changes were significantly different. At the same time clarify the potassium ion on the electrophysiological effects of cardiomyocytes and children with hypokalemia ECG changes characteristic. Confirmed the degree of children with hypokalemia and clinical manifestations, ECG changes in the three linear relationship between each other. To find out the cause of hypokalemia electrocardiogram negative changes in children pediatric hypokalemia when biochemical tests and electrocardiogram evaluation.
