特发性室早气阴两虚证患者自主神经功能的变化

Changes of Autonomic Nerve Function in Premature Ventricular Contraction Beats Patients with Deficiency of both Qi and Yin

目的探讨气阴两虚证室早患者自主神经功能变化的特点。方法与30例健康对照组相比较,分析41例室早患者自主神经功能各项指标变化,及室早、中医证候与自主神经功能的相关性。结果室早组患者的SDANN、rMSSD、PNN50显著降低,室早患者中医证候积分与rMSSD、PNN50显著负相关。结论气阴两虚证室早患者存在迷走神经功能显著降低及交感神经功能亢进,室早临床症状产生与迷走神经功能低下相关。

Objective： To observe the characteristics of autonomic nerve function in premature ventricular contraction beats（PVC） patients.Methods： Compared with 30 healthy controls,the autonomic nervous function of 41 cases PVC patients and the relationship between ventricular premature,the clinical symptoms and autonomic nervous function were analysed.Results： SDANN,rMSSD,and PNN50 were significantly lower in patients with PVC.TCM syndrome and rMSSD,PNN50 was significantly negative correlation.Conclusions： The vagus nerve function are decreased and the sympathetic nerve functionin is hyperthyroidism in PVC patients of both deficiency qi and Yin.clinical symptoms have associated with the vagus nerve function.
