前庭系统各种刺激所引起的血液动力学和心血管系统变化是多年来被研究的课题。作者们对迷路行变温刺激,于刺激前3分钟内、刺激时眼震高峰的20秒钟内及眼震静息期同时分别记录电眼震图和心脏节律图,将两种记录图送入电子计算机自动分析系统行统计学处理,对前庭心脏反射作客观评价。电眼震图可分为校准期、眼震极期和眼震静息期。节律图也有相应的三期,且二者的极点一致。评价节律图动力变化的参数为R-R平均间
The hemodynamic and cardiovascular changes caused by various stimuli in the vestibular system have been the subject of research for many years. Authors of the variable temperature stimulation of the lost, 3 minutes before stimulation, stimulation of nystagmus 20 seconds and Nystagmus at the same time were recorded electrical nystagmography and cardiac rhythm chart, the two records into the electronic Computer automatic analysis of the system line statistics, the objective evaluation of vestibular heart reflex. Electric nystagmus can be divided into the calibration period, nystagmus and nystagmus rest period. The rhythm chart also has the corresponding three phases, and the two have the same poles. Evaluation of rhythm chart dynamic changes in the parameters for the R-R averaging
