【摘要】 目的运用平板运动试验对有昼夜变化规律的小儿室性早搏(VPC)进行运动危险程度的评估。方法对423例有昼夜变化规律的VPC同时伴有心脏症状的患儿进行平板运动试验。结果平板运动试验检查发现423例VPC中,日间型197例,平板运动试验阳性51例(25.8%);夜间型226例,平板运动试验阳性29例(12.9%),二者存在显著性差异(p<0.001)。结论平板运动试验可发现潜在的危险因素,对有昼夜变化规律的频发VPC患儿运动危险程度的评估有指导意义。更多还原

【Abstract】 Objective To evaluate the day and night regularity of VPC during treadmill exercise test(TET),provide the clinical indications of exercise in pediatric.Methods 423 children with frequent(100/24h) VPC underwent TET and 24 hour dynamic electrocardiogram(DCG),all of them were absent underlying organic heart disease.Results The rate 46.6%(197/423) was the day type VPC,51 out of the 197 children(25.8%) resulted from TET positive.The rate 53.4%(226/423) was the night type VPC,29 out of the 226 children(12.9%) resulted from TET positive.There was a significance between day and night type VPCs(p<0.001).Conclusion There were different results of the day and night regularity of VPC response to exercise.The transient paroxysmal ventricular tachycardia and couplet VPC were more frequently occurred in day type VPC,TET positive was correlated with the type of VPC.Day type VPC was more dangerous than the night type VPC response to exercise.Treadmill test is helpful to predict risk in patients with the day and night regularity VPC,provides the clinical indications of exercise in pediatric.更多还原
