The analysis of beating rate provides information on the modulatory action of the autonomic
nervous system on the heart, which mediates adjustments of cardiac function to meet …

Heart rate variability (HRV), the change in the time intervals between adjacent heartbeats, is
an emergent property of interdependent regulatory systems that operate on different time …

We developed a technology for heart rate (HR) variability (HRV) analysis in the mouse for
characterization of HR dynamics, modulated by vagal and sympathetic activity. The mouse is …

Background The interactions between the autonomic nervous system (ANS), intrinsic
systems (eg, endocrine), and internal pacemaker mechanisms govern short (milliseconds …

Objective The aim of this study was to assess age-related changes in cardiac autonomic
modulation and heart rate variability (HRV) and their association with spontaneous and …

The electrical stability of the myocardium is dependent on the dynamic balance between
sympathetic and parasympathetic influences on the heart, which is reflected by heart rate …

Heart rate (HR) variability (HRV; beat-to-beat changes in the R-wave to R-wave interval) has
attracted considerable attention during the past 30+ years (PubMed currently lists> 17 000 …

The cardiovascular system is primarily controlled by the autonomic nervous system, and any
changes in sympathetic or parasympathetic activity also have an impact on myocardial …

The autonomic nervous system (ANS) is responsible for the precise regulation of tissue
functions and organs and, thus, is crucial for optimal stress reactivity, adaptive responses …

Background Autonomic responses participate in the pathophysiology of acute myocardial
infarction, but their precise time course remains unclear. Here, we investigated the …
