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 investigate the value of heart rate variability (HRV) analysis in combination with pediatric exercise test to determine the pathological premature ventricular contractions in children. Methods According to the clinical symptoms, signs and auxiliary examination, 86 children diagnosed with premature ventricular contractions were divided into 54 cases with organic heart disease (group A) and 32 cases without organic heart disease (group B) Heart rate variability (HRV) analysis and motor exercise tests were performed and the results obtained were statistically analyzed. Results Compared with HRV in both groups, heart rate variability in group A was lower than that in group B, the difference was significant (P <0.05). The results of motor cycling between two groups showed that the positive rate of A group was higher than that of B group, the difference was significant (P <0.05). Conclusion Pathological premature ventricular premature beats and autonomic dysfunction, heart rate variability analysis and exercise tests can be used for the diagnosis of pathological ventricular premature beats, the combination of the two can be more effective in the differential diagnosis of pathological premature beats, and To determine the risk of premature ventricular contractions and select the treatment program has a certain value.
