Comparison of specific features of the heart rate variability in students living in regions with different natural and climatic conditions

Modeling Septoplasty and Sensory Deprivation in Rat Olfactory Analyzer and Its Impact on the Responses of the Autonomic Nervous System

“…It is known that fluctuations in the HF component are closely associated with the release of pro-inflammatory cytokines into the bloodstream an hour after exposure to a stress factor [11]. In addition, it has been shown that an anesthetic benefit that does not correspond to the volume of surgical intervention provokes vagotonia, which affects the regulation of cardiac activity [16]. In the early stages after septoplasty in the nasal cavity, inflammatory reactions are accompanied by mucosal oedema, and this leads to narrowing of the nasal passages and subsequent hypoxemia, which, in turn, increases PNS activity, which explains the increase in HF in the second group [15].…”

Comparison of HRV Time and Frequency Domain Features for Myocardial Ischemia Detection

“…Alterations in the Heart Rate (HR) in various habitats are regarded as a sufficiently objective marker of adaptive reactions. Reduced HRV is a predictor of increased risk for cardiovascular mortality and morbidity [1]. HRV analysis includes long term analysis and short term analysis.…”

Heart Rate Variability Structure Features in Persons Born in Magadan Region Depending on Vegetative Regulation Type

“…В таком случае наблюдается неоптимальная регуляция с активацией высших уровней и повышенного тонуса симпатического отдела вегетативной нервной системы [4]. Практически это всегда отмечается при воздействии на человека неблагоприятных факторов окружающей среды, связанных с процессами адаптации его организма к различным природно-климатическим и другим экстремальным условиям [1,7].…”
