低钙血症患儿心电图ST/TP比值测定的意义

目的 探讨测定低钙血症患儿心电图ST/TP比值的临床意义.方法 采用日本福田公司NIHOH KOHDEN CardiofaxQ ECG-9130P电脑心电图系统12导联同步心电图机,对61例低钙血症患儿ST/TP比值进行检测,并与31例同期健康儿童进行对照分析,同时用临床电解质分析仪测定血清离子钙水平.采用SPSS 11.5软件进行统计学处理,P＜0.05为有统计学意义.结果 低钙血症组ST/TP比值、血清离子钙与健康组比较有显著性差异(Pa＜0.05),且低钙血症伴抽搐组ST/TP比值血清离子钙与单纯低钙血症组比较有显著性差异(P＜0.05).离子钙水平与ST/TP比值呈负相关.结论 在不能检测血清离子钙或患儿采血困难的情况下,快速进行心电图检查,ST/TP段比值可反映低钙血症患儿的病情,指导临床治疗.

Significance of ST/TP Relative Value in Electrocardiogram in Diagnosis of Hypocalcemia

Objective To evaluate the significance of ST/TP relative value in electrocardiogram in diagnosis of hypocalcemia.Methods ST/TP relative value in electrocardiogram in 61 children with hypocalcemia and 31 normal children were detected by NIHOH KOHDEN CardiofaxQ ECG-9130P electrocardiogram machine designed by Japanese futian company.Calcium ion was checked out by clinic electrolyte equipment.Results There was significant difference of ST/TP relative value between patients with hypocalcemia and normal children(P<0.05).There was significant difference of the value of calcium ion between patients with hypocalcemia and normal children also(P<0.05).There was significant difference of ST/TP relative value between the patients who had a convulsion with hypocalcemia and the patients who did not have a convulsion with hypocalcemia(P<0.05).There was significant difference of the value of calcium ion between the patients who had a convulsion with hypocalcemia and the patients who did not have a convulsion with hypocalcemia also(P<0.05).The value of calcium ion and ST/TP relative value in these groups showed correlative.Conclusions When staff can not inspect ionized calcium in blood serum,or,when children are too thin and staff can not draw blood from them,ST/TP relative value in electrocardiogram may contribute to the diagnosis of hypocalcemia,and it can reflect pathogenetic condition and help instruct cure.
