摘　　要：目的测定ST/QT比值对婴儿低钙血症的临床意义。方法应用日本光电9130-P同步十二导联心电图机对47例低钙血症患儿进行心电图检测,测定其ST/QT比值,同时用全自动生化仪测定血清总钙、离子钙浓度,与21例同期正常婴儿进行对照分析。结果婴儿低钙血症组ST/QT段比值与正常婴儿组相比有非常显著性差异。婴儿低钙血症伴抽搐组ST/QT比值与单纯婴儿低钙血症有非常显著性差异。结论新生儿、婴幼儿由于血管细小,紧急时存在采血困难的问题,在不能检测血清离子钙情况下,心电图检测ST/QT比值可反映低钙血症病情,指导临床治疗。Objective To evaluate the clinical value of ST/QT ratio to infants with hypocalcemia.Methods ST/QT ratio in electrocardiogram in 47 infants with hypocalcemia and 21 normal infants were detected by Nihon Kohden Corporation 9130-P electrocardiogram machine.Serum total calcium and serum ionized calcium in both groups were checked by automatic biochemical analyzer.Results Difference of ST/QT ratio between hypocalcemia group and control group had stitistical significance,and so in ST/QT ratio between hypocalcemia infants with spasm and hypocalcemia infants.Conclusion Electrocardiogram ST/QT ratio can point to a hypocalcemia and direct the clinic therapy under status without serum ionized calcium detection in infants with tiny vessel which is difficult for emergent blood collection.
