Objective To evaluate gut autonomic function tests in healthy subjects(HS) and its significance. Methods Heart rate variability (HRV) analysis and standard cardiac autonomic test were performed before and after test meal in HS ( n = 18 ). Results 1) Though heart rate increased significantly, there was no difference between pre and postprandial autonomic function by standard autonomic test in HS. 2) Sympathetic to parasympathetic balance increased (P <0. 05) and parasympathetic function decreased (P <0. 01) after test meal by HRV analysis in HS. Con- , elusions Test meal combined with cardiac autonomic function test may help to reflect gastrointestinal autonomic nerve function. HRV analysis combined with test meal is better than standard cardiac autonomic test.%目的 本研究旨在评价健康人胃肠道自主神经功能检查方法及其意义.方法 分别采用心率变异(HRV)分析及标准心血管自主神经检查,比较健康志愿者餐前、餐后自主神经功能.结果 1)健康志愿者餐后心率高于餐前.但餐前、后标准心血管自主神经功能无差异.2)HRV分析发现,健康志愿者餐后与餐前比较,交感成分增强(P＜0 05),交感-副交感比例增加(P＜0.05),而副交感成分减弱(P＜0.01).结论 进餐联合心血管自主神经功能检查可能有助于反映胃肠道自主神经功能.HRV分析比标准心血管自主神经功能检查具有优势.
