本文总结分析了47例小儿心电图蹲立运动试验的结果。阳性者10例,可疑阳性5例,这10例阳性均为心肌炎患儿,说明蹲立运动试验对小儿心肌炎的诊断确有一定的参考意义。但受检的28例心肌炎患儿中,阴性有16例占57.1%,这说明本试验对一部分小儿心肌炎不够敏感,可能与运动量偏小有关。因此我们提出了“小儿亚次极量运动试验”作为改进的方法,增加运动负荷量,使运动后即刻心率达到150～160次/分,以求进一步提高阳性率。
This article summarizes the results of 47 cases of pediatric electrocardiogram crouch movement test. Positive in 10 cases, 5 were suspicious positive, these 10 cases were positive in children with myocarditis, cataract exercise test on the diagnosis of pediatric myocarditis does have some reference value. However, 28 cases of children with myocarditis were negative in 16 cases accounted for 57.1%, indicating that the test is not sensitive enough for some children with myocarditis, may be related to exercise less. Therefore, we proposed “sub-sub-maximal motor test in children” as an improved method to increase the exercise load, heart rate immediately after exercise to 150 to 160 beats / min, in order to further improve the positive rate.
