摘　　要：目的探讨心率变异性分析与小儿脚踏车运动试验联合应用对判定小儿病理性室性早搏的应用价值。方法根据临床症状、体征及辅助检查将86例确诊室性早搏儿童分为有器质性心脏病组(A组)54例和无器质性心脏病组(B组)32例,分别对其进行心率变异(HRV)分析与脚踏车运动试验检查,所得结果应用统计学方法处理。结果两组儿童HRV比较,A组较B组心率变异性降低,差异有显著性(P<0.05)。两组儿童脚踏车运动试验结果比较,A组阳性率高于B组,差异有显著性(P<0.05)。结论病理性室性早搏多与自主神经功能受损有关,心率变异性分析与运动试验均可用于病理性室性早搏的诊断,二者联合应用可更有效辅助病理性早搏的鉴别诊断,并且对判定室性早搏的危险程度及选择治疗方案有一定的应用价值。Objective To study the application value of heart rate variability analysis and cycle ergometer exercise test for the decision of pathological ventricular premature contraction in children.Methods 86 children of ventricular premature contraction were divided into structural heart disease group （Group A） and without structural heart disease group （Group B）,and they were treated by heart rate variability （HRV） analysis and exercise test respectively.Results There were both significant differences between the two groups by comparison of HRV and by comparison of exercise test results.Conclusion Pathological ventricular premature contraction was mostly related with the damage of autonomic nervous system.The heart rate variability analysis and exercise test are both helpful to diagnose ventricular premature contraction,and there was an important significance for their combined application to decide diagnose ventricular premature contraction.
