先天性心脏病儿童与正常儿童圆顶尖角型T波的比较

The distinguish of dome and dart T waves between children suffered from congenital heart disease and healthy children

目的比较先天性心脏病患儿与超声心动图正常儿童的圆顶尖角型T波在形态及高度上的区别。方法回顾性分析本院2015年12月—2016年12月间心电图检查出圆顶尖角T波的儿童心电图114例,根据超声心动图结果分成先天性心脏病组(先心病组)71例和超声心动图正常组(正常组)43例,通过测量2组圆顶尖角型T波的高度比较2组圆顶尖角型T波在形态上的区别;先心病组患者根据先天性心脏病种类不同分组,比较各组间圆顶尖角型T波的高度。结果与正常组相比,先心病组的圆顶尖角型T波的第二峰大于第一峰的比例更高(52.11%vs. 18.60%),且第二峰尖角波高度更高。不同先天性心脏病病种之间圆顶尖角型T波在高度及形态上差异无统计学意义(P>0.05)。结论圆顶尖角型T波可出现在先天性心脏病患儿心电图中,亦可出现在超声心动图正常儿童心电图中,但先天性心脏病患儿有着更高的尖角T波,且第二峰高于第一峰。

Objective To investigate the distinguish of dome and dart T waves between children suffered from congenital heart disease and healthy children. Methods Data of 114 children with ECGs of dome and dart T waves were retrospectively analyzed. According to echocardiography these children were divided into two groups, congenital heart disease group （n=71） and healthy group （n=43）. The amplitude and the waveforms of dart T wave were measured and compared between two groups. Results In contrast to healthy group, congenital heart disease group showed a significantly higher dart T wave. The proportion of amplitude of dart T wave was higher than dome T wave in congenital heart disease group than that of healthy group （52.11% vs. 18.60%）. There were no significant differences in the height and morphology of dart T wave between different kinds of congenital heart diseases （P 〉 0.05）. Conclusion Dome and dart T waves can be observed in ECGs of children with congenital heart disease and healthy children. The dart T wave is pronfinent in congenital heart disease, and the dart wave is higher than the dome wave.
