摘　　要：目的探讨动态心电图(DCG)联合平板运动试验(TET)对室性早搏伴运动风险患儿的诊断价值。方法选取2022年10月至2023年12月我院疑似室性早搏伴运动风险患儿72例,均接受DCG和TET检查,以临床综合诊断结果为“金标准”,分析DCG、TET单独和联合检查的诊断结果和诊断效能。结果72例疑似室性早搏伴运动风险患儿中,经DCG检查显示阳性56例,阴性16例;TET检查显示阳性56例,阴性16例;联合检查显示阳性62例,阴性10例。联合检查灵敏度、准确性分别为98.39%(61/62)、97.22%(70/72),均明显高于DCG检查的87.10%(54/62)、86.11%(62/72)以及TET检查的85.48%(53/62)、83.33%(60/72)(P<0.05);与无运动风险患儿相比,有运动风险患儿运动总时间明显较短,Load_(max)、HR_(max)明显较低,且HR_(end)明显较高(P<0.05)。结论动态心电图联合平板运动试验诊断室性早搏伴运动风险患儿能提升诊断灵敏度和准确性,值得临床进一步推广应用。Objective To explore the diagnostic value of dynamic electrocardiography(DCG)combined with treadmill exercise test(TET)in children with premature ventricular contraction complicated with exercise risk.Methods 72 children with suspected premature ventricular contraction complicated with exercise risk in our hospital from October 2022 to December 2023 were selected and given DCG and TET.Taking the clinical diagnosis as the gold standard,the diagnostic results and diagnostic efficacy of single and combined detection of DCG and TET were analyzed.Results Among the 72 children with suspected premature ventricular contraction complicated with exercise risk,56 cases were positive and 16 cases were negative by DCG,56 cases were positive and 16 cases were negative by TET,and 62 cases were positive and 10 cases were negative by combined detection.The sensitivity and accuracy of the combined detection were 98.39%(61/62)and 97.22%(70/72),respectively,significantly higher than 87.10%(54/62)and 86.11%(62/72)of DCG,and 85.48%(53/62)and 83.33%(60/72)of TET(P<0.05).Compared with the children without exercise risk,the children with exercise risk had shorter total exercise time,lower Load_(max) and HR_(max),and higher HR_(end)(P<0.05).Conclusions Dynamic electrocardiography combined with treadmill exercise test can improve the sensitivity and accuracy in the diagnosis of children with premature ventricular contraction complicated with exercise risk,which is worthy of further clinical promotion and application.
