摘要
目的探讨不同类型血管迷走性晕厥(VVS)患儿的临床特征及实验室检查指标间的差异。方法经常规病史询问、体格检查、卧立位血压、辅助检查、直立倾斜试验(HUT)确诊的VVS患儿40例,比较不同类型患儿的临床特征及实验室指标间的差异。结果VVS患儿的血流动力学类型以血管抑制性为主。不同类型VVS患儿的临床特征,包括晕厥的诱因、先兆、发作频率、持续时间、基础心率、血压及血清电解质水平等均无显著差异。结论血管抑制型反应是血管迷走性晕厥患儿的主要血流动力学类型。
Objective To explore the difference of clinical features and laboratory indexs with different vasovagal responses in head up tilt test（HUT） in children with vasovagal syncope（VVS）. Methods Forty consecutive children diagnosed with VVS by HUT were analyzed. The vasovagal responses were divided into vasodepressor,eardioinhibitory and mixed patterns. The distribution and different clinical features and laboratory indexs of different response patterns in the VVS were studied. Results The most common vasovagal response was vasodepressor. There was no significant difference in their clinical features, including the motivation, presymptom, frequency and duration of syncope, baseline heart rate and blood pressure, and serum electrolytes among the children with different vasovagal responses. Conclusion Vosodepressor response is the most common hemodynamic pattern in vasovagal syncope in children.
