Time Series Analysis using Embedding Dimension on Heart Rate Variability [PDF]

, 2018
Heart Rate Variability (HRV) is the measurement sequence with one or more visible variables of an underlying dynamic system, whose state changes with time. In practice, it is difficult to know what variables determine the actual dynamic system.

A cholinergic-sympathetic pathway primes immunity in hypertension and mediates brain-to-spleen communication [PDF]

, 2016
The crucial role of the immune system in hypertension is now widely recognized. We previously reported that hypertensive challenges couple the nervous drive with immune system activation, but the physiological and molecular mechanisms of this connection ...

Baroreflex Modulation During Acute High-Altitude Exposure in Rats

Frontiers in Physiology, 2020
Baroreflex (BR) control is critically dependent of sympathetic and parasympathetic modulation. It has been documented that during acute hypobaric hypoxia there is a BR control impairment, however, the effect of a natural hypoxic environment on BR ...

Sympathetic Nervous System Mediates Cardiac Remodeling After Myocardial Infarction in a Circadian Disruption Model

Frontiers in Cardiovascular Medicine, 2021
Background: Circadian rhythms have a considerable impact on the daily physiology of the heart, and their disruption causes pathology. Several studies have revealed that circadian disruption impaired cardiac remodeling after myocardial infarction (MI ...
