Abstract

Interrelation between amplitude and frequency of the α- and β- brain waves, heart rate variability (HRV) and hemodynamics was studied in 65 hypertensive patients (level 2) and compared to 75 healthy people. Methods of the investigations included EEG, 24-hour Holter monitoring, echo-cardiography, blood pressure measurement and HRV calculation. In patients, α and β parameters decreased by 27 to 35 %, respectively. In comparison to normal people, reductions of α and β amplitudes as well as powers made up 20%, 30 % and 16–45 %, respectively. Total HRV in patients decreased 60 %. Interrelations between the α- and β- waves, HRV and hemodynamics were numerous and multidirectional in patients, whereas in normal people they were weak or absent at all. The results evidence interrelations between the cerebral bioelectrical activity, sympathetic heart rate regulation and hemodynamics in hypertensive patients living in a midaltitude region.

中高海拔地区高血压患者脑生物电活动、心律交感调节和血流动力学的相互关系

本文研究了65例2级高血压患者的α-和β-脑电波振幅和频率、心率变异性(HRV)和血流动力学之间的相互关系，并与75名健康人进行了比较。调查方法包括脑电图、24小时动态心电图、超声心动图、血压测量和HRV计算。在患者中，α和β参数分别下降了27%至35%。与正常人相比，α、β振幅和功率分别下降了20%、30%和16 - 45%。患者的总HRV下降了60%。在患者中，α波和β波、HRV和血流动力学之间的相互关系是多方面的，而在正常人中，它们之间的相互关系很弱或根本不存在。结果表明，生活在中高海拔地区的高血压患者的大脑生物电活动、交感心率调节和血流动力学之间存在相互关系。
