目的 报告踏车试验 (EET)临床应用的结果 ,探讨EET在儿科应用的指征和价值。方法 用EGM ⅢC型踏车心功量仪对 2 6 8例 4～ 14岁患儿进行亚极量运动负荷试验 ,以心电图作为主要检测指标。结果 36例判断为阳性 (13 4% ) ;2 9例为可疑阳性 (10 8% )。EET总阳性率在有心源性症状者为 2 1 4% ,心肌炎恢复期为 32 5 % ,功能性早搏为 36 4% ,与对照组比较差异均有显著性 (P <0 0 1)。结论 EET对儿童心血管症状体征和心功能的评价都有相当的价值 ,应进一步规范化并扩大临床应用
Objective To report the results of clinical application of treadmill test (EET) and to explore the indications and values of EET in pediatric application. Methods The submaximal exercise load test was performed in 246 cases of children aged 4 to 14 years with EGM ⅢC treadmill electrocardiograph, and the electrocardiogram was taken as the main detection index. Results 36 cases were positive (13 4%); 29 cases were suspicious (108%). The total positive rate of EET was 21.4% in cardiogenic symptoms, 32.5% in myocarditis convalescent and 36.4% in functional premature beats, which was significantly different from the control group (P <0.01). Conclusion EET has considerable value in the evaluation of children’s cardiovascular symptoms and signs and heart function, and should be further standardized and expanded clinical application
