摘 要:目的:观察抗胆碱药盐酸戊乙奎醚(penehyclidine hydrochloride,PH)对健康受试者心率及心率变异性的作用,初步探讨其对自主神经活动的影响。方法:健康受试者26例,男女各半,年龄20~30岁,随机分为0.3,0.4,0.6,0.8和1.0 mg PH组,单次给药。每个剂量组随机选择2例(男女各1例)受试者行24 h动态心电图监测,采集健康受试者给药前后24 h的平均心率及心率变异性时域参数(SDNN,SDNN Idx,r MSSD,SDANN,p NN50,TI);其余16例受试者采用常规心电图监测记录给药前后24 h心率。比较给药前后24 h心率,并采用心率变异性(heart rate variability,HRV)时域分析法考察心率变异性的变化。结果:PH给药后,常规心电图显示受试者心率明显减慢(P〈0.05);动态心电图监测结果表明受试者24 h平均心率与给药前相比显著减慢(P〈0.01),1 h SDNN显著提升(P〈0.01),24 h长程SDNN,SDNN Idx,r MSSD,p NN50和TI水平较给药前呈上升趋势;SDANN水平略低于给药前。结论:PH可能通过非M2受体或增强迷走神经张力影响HRV,进而减慢心率。Objective: To observe effect of penehyclidine hydrochloride (PH) on heart rate and heart rate variability as well as its activity on autonomic nervous system in healthy volunteers. Methods: A total of 26 healthy volunteers were enrolled in a randomized, opened study. They were randomized to be divided into 5 groups and o- rally received PH 0.3 ~ 1.0 mg daily. Two healthy volunteers were selected from each group and monitored by dy- namic electrocardiography recording 24-h average heart rate; parameters of time domain including SDNN, SDNN Idx, SDANN, rMSSD, pNN50 and TI were analyzed for evaluating heart rate variability. Other 16 healthy volun- teers accepted routine electrocardiography to record heart rate. Data from average heart rate and parameters of heart rate variability befoe and after oral PH were analyzed by professional software. Results: Compared with baseline level, average heart rate of healthy subjects within 24 h was significantly retarded after PH administration (P 〈 0.01) , and SDNNs were significantly increased (P 〈 0.01 ) in 5 PH dose groups. Other parameters including SDNN Idx, rMSSD, pNN50 and TI were slightly prolonged, and SDANN was shortened a little (P 〈 0.05). Con- clusion: PH retards heart rate, which may be mediated by the way of non-M2 receptor or strengthened vagal tone.
