BACKGROUND: The analysis of heart rate variability is important to the investigation of stimuli from the autonomic nervous system. Osteopathy is a form of treatment that can influence this system in healthy individuals as well as those with a disorder or disease. OBJECTIVES: The aim of the present study was to perform a systematic review of the literature regarding the effect of spinal manipulation and myofascial techniques on heart rate variability. METHODS: Searches were performed of the Pubmed, Scielo, Lilacs, PEDro, Ibesco, Cochrane and Scopus databases for relevant studies...

Over the past few decades, it has been clarified that the nervous system and immune system have overlapping distributions and their interactions are critical in the regulation of immunological and inflammatory responses. The cholinergic anti-inflammatory pathway, including the parasympathetic nerve systems and humoral factors orchestrate the immune responses to protect the body during infection and tissue injury. Recent investigations have attempted to clarify how the parasympathetic nerve systems attenuate the systemic inflammatory responses and identified the α7 nicotinic acetylcholine receptor (α7nAChR) as a crucial target for attenuating the release of inflammatory cytokines from inflammatory cells including macrophages and dendritic cells...

Sound stimuli such as fireworks, firearms, and claps of thunder have been used as a stress reactivity model for dogs. Acupuncture has been widely used to treat and prevent physiological and behavioural disorders induced by stress. Our study aims to evaluate the effects of acupuncture on cardiac autonomic modulation (heart rate variability - HRV), behavioural (reactivity) and endocrine (cortisol levels) responses in dogs exposed to sounds of thunder. Twenty-four laboratory beagles (12 males and 12 females, 1-6years old) with no history of phobia to thunder were subjected to a sound stimulus that consisted of a standardized recording of thunder over a 150s period with a maximum intensity of 103-104dB...

Dravet syndrome (DS) is a severe childhood-onset epilepsy commonly due to mutations of the sodium channel gene SCN1A. DS patients have a high risk of sudden unexplained death in epilepsy (SUDEP), believed to be due to cardiac mechanisms. Here we show that DS patients have peri-ictal respiratory dysfunction. One patient who had severe and prolonged postictal hypoventilation later died of SUDEP. Mice with an Scn1aR1407X/+ loss of function mutation died after spontaneous and heat-induced seizures due to central apnea followed by progressive bradycardia...

In the article the features of the autonomic nervous system state were estimated by the method of heart rate variability in patients with cirrhosis with syntropic damages of cardiovascular system - cardiomyopathy and arterial hypotension. As a result of an examination of 50 patients with liver cirrhosis and cardiomyopathy (investigational group A), 54 patients with liver cirrhosis and arterial hypotension (investigational group B), and 45 patients with liver cirrhosis also those who don't have the damages of cardiovascular system (group of comparison) it was established that: 1) they have the peculiarities of vegetative imbalance the characteristics of which are the low summarized activity of vegetative influence on heart rhythm and special dynamics of indexes of percentage structure of general spectral power; 2) they depend on the clinical variant of this damage - in patients with cirrhosis and syntropic cardiomyopathy the regulating of internal processes involve the humoral-metabolic influence, i...

Reduced activity of vagal efferents has long been implicated in schizophrenia and appears to be responsible for diminished parasympathetic activity and associated peripheral symptoms such as low heart rate variability and cardiovascular complications in affected individuals. In contrast, only little attention has been paid to the possibility that impaired afferent vagal signaling may be relevant for the disorder's pathophysiology as well. The present study explored this hypothesis using a model of subdiaphragmatic vagal deafferentation (SDA) in male rats...

Parasympathetic processes appear to underlie maladaptive parent-child interactions in maltreating families, but it is unknown whether parent-child coregulation of respiratory sinus arrhythmia (RSA) differs by child maltreatment severity and subtype. RSA coregulation in maltreating and nonmaltreating mother-child dyads ( N = 146; age 3-5 years) during two dyadic tasks was analyzed using dynamic time series modeling. Nonmaltreating dyads showed positive RSA concordance but maltreating dyads (when examined as one group) did not...

Heart rate variability (HRV) refers to the variations between consecutive heartbeats, which depend on the continuous modulation of the sympathetic and parasympathetic branches of the autonomic nervous system. HRV has been shown to be effective as a predictor of risk after myocardial infarction and an early warning sign of diabetic neuropathy, and in the cardiology setting is now recognized to be a useful tool for risk-stratification after hospital admission and after discharge. Recent evidences suggest that HRV analysis might predict complications even in patients undergoing cardiac surgery, and the present review summarizes the importance of HRV analysis in adult cardiac surgery and the perspectives for HRV use in current clinical practice...

The autonomic nervous system plays a leading role in the control of fetal homeostasis. Fetal heart rate variability (HRV) analysis is a reflection of its activity. We developed a new index (the Fetal Stress Index, FSI) reflecting parasympathetic tone. The objective of this study was to evaluate this index as a predictor of fetal acid-base status. This was an experimental study on chronically instrumented fetal lambs (n = 11, surgery at 128 +/- 2 days gestational age, term = 145 days). The model was based on 75% occlusion of the umbilical cord for a maximum of 120 minutes or until an arterial pH ≤ 7...

BACKGROUND: It has been difficult to prove that the "catecholamine-induced cardiomyopathy" contributes to the mechanism of sudden cardiac death in Chagas heart disease. Also, it is almost impossible to rule out the possibility that is not involved in the process. More importantly, the vagal-cholinergic pathway in the ventricle plays a direct role in the prevention of the initiation of complex ventricular arrhythmias, including non-sustained ventricular tachycardia, ventricular fibrillation responsible for sudden death...

The heart rate is dynamically controlled by the sympathetic and parasympathetic nervous systems that regulate the sinoatrial node (SAN). HCN4 pacemaker channels are well-known causative molecule of congenital sick sinus syndrome. Although HCN4 channels are activated by cAMP, the sympathetic response of SAN was preserved in the patients carrying loss-of-function mutations of HCN4 gene. In order to clarify the contribution of HCN4 channels in the autonomic regulation of SAN, we developed novel gain-of-function mutant mice in which expression level of HCN4 channels could be reversibly changed from zero to ∼3 times of that in wild type mice, using tetracycline trans-activator and tetracycline responsive element...

An unusual, but common, aversion to images with clusters of holes is known as trypophobia. Recent research suggests that trypophobic reactions are caused by visual spectral properties also present in aversive images of evolutionary threatening animals (e.g., snakes and spiders). However, despite similar spectral properties, it remains unknown whether there is a shared emotional response to holes and threatening animals. Whereas snakes and spiders are known to elicit a fear reaction, associated with the sympathetic nervous system, anecdotal reports from self-described trypophobes suggest reactions more consistent with disgust, which is associated with activation of the parasympathetic nervous system...

Coping Power is an evidence-based preventive intervention for youth with aggressive behavior problems that has traditionally been delivered in small group formats, but because of concerns about potentially diminished effects secondary to aggregation of high-risk youth, an individual format of Coping Power has been developed. The current study examined whether physiological characteristics of the child may provide information about which intervention delivery format works best for that individual. Indicators of sympathetic and parasympathetic nervous system functioning were examined in 360 fourth-grade children (65% male; 76...

BACKGROUND: Previous studies have reported adverse health effects of indoor air pollutants especially particulate matter (PM) and black carbon (BC). Patients with chronic obstructive pulmonary disease (COPD) have been shown to be more likely with cardiovascular comorbidities in which cardiac autonomic dysfunction plays an important role. However, there is little evidence for the effect of indoor PM and BC exposures on cardiac autonomic function in COPD patients. OBJECTIVES: To evaluate the association between exposure to indoor size-fractioned PM and BC and changes in HRV and HR in COPD patients...

The autonomic nervous system exerts broad control over the involuntary functions of the human body via complex equilibrium between sympathetic and parasympathetic tone. Imbalance in this equilibrium is associated with a multitude of cardiovascular outcomes, including mortality. The cardiovascular static state of this equilibrium can be quantified via physiological parameters such as heart rate, blood pressure and by spectral analysis of heart rate variability.Here we review the current state of knowledge of the genetic background of cardiovascular measurements of autonomic tone...

The cranial nerves IX and X emerge from medulla oblongata and have motor, sensory, and parasympathetic functions. Some of these are amenable to neurophysiological assessment. It is often hard to separate the individual contribution of each nerve; in fact, some of the techniques are indeed a composite functional measure of both nerves. The main methods are the evaluation of the swallowing function (combined IX and X), laryngeal electromyogram (predominant motor vagal function), and heart rate variability (predominant parasympathetic vagal function)...
