Heart Rate Variability, or HRV for short, is the measure of variation in timing between successive heart beats. It has been shown that heart rate and HRV are regulated by both the sympathetic (SNS) and parasympathetic (PSNS) branches of the autonomic nervous system (ANS). Only looking at total variability, or by simply reporting heart rate, it is not clear which side of the autonomic nervous system is active at a given time. Depending on what is being studied, it can be desirable to distinguish between sympathetic and parasympathetic influence.. By breaking down HRV into frequency components, it is possible to isolate a specific range of frequencies which has been shown to correlate almost exclusively to parasympathetic nervous system activity. This range of frequencies, known as high frequency HRV, is associated with a physiological phenomenon known as Respiratory Sinus Arrhythmia (RSA). This blog series is intended to discuss the process by which this and many more statistics are calculated ...

Heart Rate Variability (HRV) and respiratory sinus arrhythmia are directly associated with autonomic flexibility, self-regulation and well-being, and inversely associated with physiological stress, psychological stress and pathology.

Two experiments were conducted to measure both the psychological and physiological effects of touching on the HPA axis related parts of the body. HPA stands for the hypothalamus, pituitary, and adrenal. One experiment was conducted with a group of healthy experiment participants, and another was with a group of traumatized participants who had Adverse Childhood Experiences (ACE). In the experiments, the back of an experiment participant was touched, where a kidney-adrenal was supposed to reside, and both the psychological and physiological effects were measured. As a result, respiratory sinus arrhythmia (RSA), an indicator of the parasympathetic nerve system function and, especially, an indicator of the social engagement system increased, by a statistically significant degree, as a consequence of HPA touching in both the healthy and the trauma group, in comparison with the control. The traumatized participants had a lower RSA, and this was increased by HPA touching, accompanied by a decrease of the

The present study examined the ability of a Virtual Reality (VR) public speaking task to elicit physiological arousal in adults with SAD (n=25) and Controls (n=25). A behavioral assessment paradigm was employed to address three study objectives: (a) to determine whether the VR task can elicit significant increases in physiological response over baseline resting conditions (b) to determine if individuals with SAD have a greater increase from baseline levels of physiological and self-reported arousal during the in vivo speech task as opposed to the VR speech task and (c) to determine whether individuals with SAD experience greater changes in physiological and selfreported arousal during each speech task compared to controls. Results demonstrated that the VR task was able to elicit significant increases in heart rate, skin conductance, and respiratory sinus arrhythmia, but did not elicit as much physiological or self-reported arousal as the in vivo speech task. In addition, no differences were found

In general patients who show a sinus bradycardia on their ECG will show little other signs and symptoms depending on the rate of their rhythm and any co-factors such as an acute coronary syndrome, pain, injuries, etc. Most patients will appear well perfused with good skin colour, warmth and no diaphoresis. If patients are on common blood pressure medications such as Beta Blockers it is likely that these will have artificially lowered the persons heart rate and that their normal resting heart rhythm is a sinus bradycardia.. In general, patients who have a sinus bradycardia are not hypotensive. This is because as we learned in Starlings Law, the slower the heart rate the greater time allowed for ventricular filling (which is passive), ventricular stretching (pre-load) and subsequent cardiac output.. ...

A sinus rhythm is any cardiac rhythm where depolarization of the cardiac muscle begins at the sinus node. It is characterised by the presence of correctly oriented P waves on the electrocardiogram (ECG). Sinus rhythm is necessary, but not sufficient, for normal electrical activity within the heart. The term normal sinus rhythm (NSR) is sometimes used to denote a specific type of sinus rhythm where all other measurements on the ECG also fall within designated normal limits, giving rise to the characteristic appearance of the ECG when the electrical conduction system of the heart is functioning normally. However, other sinus rhythms can be entirely normal in particular patient groups and clinical contexts, so the term is sometimes considered a misnomer and its use is sometimes discouraged. Other types of sinus rhythm which can be normal include sinus tachycardia, sinus bradycardia and sinus arrhythmia. Sinus rhythms may be present together with various other cardiac arrhythmias on the same ECG. ...

Arrhythmia occurs when the hearts rhythm becomes disturbed or arrhythmic. The most common form of arrhythmia is a heart palpitation, known as sinus arrhythmia. More serious forms of heart arrhythmia include atrial fibrillation, ventricular tachycardia and ventricular fibrillation. Arrhythmia requires medical treatment; some rhythm disturbances are addressed through the use of medications, defibrillation, or a pacemaker. Natural options for heart support include fish oil, hawthorn, vitamin C and magnesium.

Sinus bradycardia is a type of slow heartbeat. A special group of cells begin the signal to start your heartbeat. These cells are in the sinoatrial (SA) node. Normally, the SA node fires at about 60 to 100 times per minute at rest. In sinus bradycardia, the node fires less than 60 times per minute.

An arrhythmia (also called irregular heartbeat) is a problem with the rate or rhythm of the heart. In an arrhythmia, the heart could either beat too fast, too slowly, or with an irregular pattern.

The steady lup-dup, lub-dup regularity of our hearts pumping beat is reassuring, and we dont mind it speeding up for exercise or slowing down for sleep, as long as its rhythm remains steady. Any glitch in that rhythmic throb, whether too slow or too fast, is called an arrhythmia. In either case, you can feel dizzy or lightheaded because not enough blood is getting to the brain when the heart rhythm is off-kilter. To assess and correct an arrhythmia requires a medical professional. Many times it...

Heart rate variability (HRV), the beat-to-beat variation in either heart rate or the duration of the R-R interval - the heart period, has become a popular clinical and investigational tool. The temporal fluctuations in heart rate exhibit a marked synchrony with respiration (increasing during inspiration and decreasing during expiration - the so called respiratory sinus arrhythmia, RSA) and are widely believed to reflect changes in cardiac autonomic regulation. Although the exact contributions of the parasympathetic and the sympathetic divisions of the autonomic nervous system to this variability are controversial and remain the subject of active investigation and debate, a number of time and frequency domain techniques have been developed to provide insight into cardiac autonomic regulation in both health and disease. It is the purpose of this essay to provide an historical overview of the evolution in the concept of heart rate variability. Briefly, pulse rate was first measured by ancient Greek

1. Although the high-frequency fluctuations in R-R interval (respiratory sinus arrhythmia) observed in heart transplant recipients are not a reliable marker of reinnervation because of a previously shown direct mechanical effect of breathing, the presence of a non-respiration-related low-frequency oscillation reflects rhythms generated outside the heart, and thus could be neurally mediated.. 2. To evaluate the presence of reinnervation, the spontaneous variability in R-R interval was investigated, supine and after passive tilting, in 23 heart transplant recipients (age 43 years, range 23-64 years) and in 25 normotensive control subjects by autoregressive spectral analysis of low- and high-frequency spontaneous fluctuations in R-R interval and respiration. The response of R-R interval to amyl nitrite inhalation was also evaluated in five heart transplant recipients and eight control subjects.. 3. Detectable low-frequency oscillations, unrelated to respiration, were present in 13/23 heart ...

The cardiovascular and respiratory systems are functionally related to each other, but the underlying physiologic mechanism of cardiorespiratory coupling (CRC) is unclear. Cardiopulmonary phase synchronization is a form of cardiorespiratory coupling. However, it is difficult to study in experimental data which are very often inherently nonstationary and thus contain only quasiperiodic oscillations. So how to enhance cardiopulmonary synchronization and quantify cardiopulmonary synchronization, the changes in cardiac function under the conditions of cardiopulmonary synchronization, and the physiological mechanisms behind them are the main issues to be discussed in this paper. The results showed that the cardiorespiratory synchronization significantly increased when breathing was controlled by heartbeat detection (p | 0.001). And the respiratory sinus arrhythmia (RSA) obviously decreased (p | 0.01) in the 2/2 mode and increased (p | 0.001) in the 4/4 mode. During the 2/2 breathing pattern compared with

Treatment strategy of sinus node dysfunction after the maze procedure is largely dictated by patients symptoms and electrocardiographic findings. Continuous monitoring of the rhythm and stand by modus of ventricular pacing on demand are important during the early postoperative course after the maze procedure because some of the patients may be intermittently asystole. Sinus arrhythmia, sinus tachycardia, and nonphysiological sinus tachycardia do not need pacemaker implantation (11). Sinus pause or arrest longer than 3 s is rarely an indication for pacemaker implantation in patients with the maze procedure because they were uncommonly associated with symptoms in our patients. However, in patients other than those with the maze procedure, these electrocardiographic findings may be combined with the symptoms and therefore may require pacemaker implantation (24), although some found symptoms to be uncommon during such pauses, and prognosis was not altered by cardiac pacing (25). Nevertheless, ...

Here, we show that HCN1 channels make up a physiologically relevant component of If in the SAN. If was reduced by ≈30% in HCN1−/− SAN cells, and the activation kinetics of the remaining If was significantly slowed down. Our results also suggest that HCN1 is functionally important in spindle and elongated primary pacemaker cells of the central SAN. The main cardiac phenotype of the HCN1−/− mouse is a pronounced sinus node dysfunction characterized by impaired impulse formation and sinoatrial conduction, resulting in bradycardia, sinus arrhythmia, and recurrent sinus pauses. Hemodynamically, these changes lead to a relevant reduction in cardiac output.. Several mechanisms may contribute to this complex phenotype. First, a reduction in If density is an important factor that could contribute to or explain the bradycardia observed in HCN1−/− mice. Heterologous expression studies and analysis of neuronal hyperpolarization-activated currents predominantly carried by HCN1 revealed that the ...

Abstract: The vagal tank theory, building on neurophysiological, cognitive and social psychology approaches, will introduce a physiological indicator for self-regulation that has mainly been ignored from cognitive and social psychology, cardiac vagal control. Cardiac vagal control reflects the contribution of the vagus nerve, the main nerve of the parasympathetic nervous system, to cardiac regulation. Cardiac vagal control is proposed to be an indicator of how efficiently self-regulatory resources are mobilized and used. Three systematic levels of cardiac vagal control functioning are suggested, the 3 Rs: Resting ...

Introduction: In cohort studies, increased resting heart rate is a risk factor for cardiovascular mortality as well as sudden death after myocardial infarction. Hypothesis: We hypothesized that resting heart rate is a determinant of sudden cardiac arrest (SCA) in the community.. Methods: Cases of SCA with coronary artery disease (CAD) from an ongoing population-based study in the Northwest US were included (population approximately one million). Controls were residents with CAD without SCA. Subjects were required to have a 12-lead ECG with measurement of resting heart rate. For cases, the ECG closest and unrelated to the occurrence of SCA was evaluated and showed sinus rhythm (89%), sinus arrhythmia (2%), atrial fibrillation (8%) and atrial flutter (1%). Independent samples t-tests and Pearsons chi-square tests were used for case-control comparisons of continuous and categorical variables, respectively. Logistic regression was used to estimate the association of heart rate with SCA.. Results: A ...

Loss-of-function mutations in ANK2 can result in a broad spectrum of clinical cardiac phenotypes. Carriers of some mutations (e.g., E1425G, {106410.0001}) display QT interval prolongation, stress- and/or exercise-induced polymorphic ventricular arrhythmia, syncope, and sudden cardiac death. Patients with other variants show clinical phenotypes, sometimes mild, extending beyond LQTS, leading to the label ankyrin-B syndrome. These phenotypes include bradycardia, sinus arrhythmia, delayed conduction/conduction block, idiopathic ventricular fibrillation, and catecholaminergic polymorphic ventricular tachycardia ({1:Mohler et al., 2007 ...

Description: Description of target: Galanin is an important neuromodulator present in the brain, gastrointestinal system, and hypothalamopituitary axis. It is a 30-amino acid non-C-terminally amidated peptide that potently stimulates growth hormone secretion, inhibits cardiac vagal slowing of heart rate, abolishes sinus arrhythmia, and inhibits postprandial gastrointestinal motility. The actions of galanin are mediated through interaction with specific membrane receptors that are members of the 7-transmembrane family of G protein-coupled receptors. GALR2 interacts with the N-terminal residues of the galanin peptide. The primary signaling mechanism for GALR2 is through the phospholipase C/protein kinase C pathway (via Gq), in contrast to GALR1, which communicates its intracellular signal by inhibition of adenylyl cyclase through Gi. However, it has been demonstrated that GALR2 couples efficiently to both the Gq and Gi proteins to simultaneously activate 2 independent signal transduction ...

Expert advice by veteran Family Therapist and Psychologist. Janette Strokappe - Online Counselor and Therapist. For many years, the autonomic nervous system was thought to be the sympathetic nervous system in balance with the parasympathetic nervous system. The sympathetic revved the body up and the parasympathetic calmed it down.. Dr. Stephen Porges Polyvagal Theory changed all that. As I am just summarizing the polyvagal theory, if you want more thorough information, just google Polyvagal theory.. Dr. Porges discovered that the parasympathetic system is composed of two branches of the vagus nerve which arise from different areas of the brain.. The unmyelinated branch is an ancient system found also in reptiles. Its action is below the diaphragm. Myelin is the outer coating of a nerve which allows it to transmit impulses more efficiently. This branch lacks myelin.. The ventral vagus which we are interested in is found only in mammals and it is myelinated. It arises from the brain very close to ...

The objective of the project is to study clinical and prognostic value of new echocardiographic technique, so called positive preejection velocity (+VIC), in patients with chronic ischemic left ventricular (LV) dysfunction indicated for revascularization. Pilot studies has shown high accuracy of pulsed Tissue Doppler imaging (TDI)-derived resting pattern of +VIC to detect viable myocardium in patients with both acute myocardial infarction and chronically dysfunctional myocardium. The aim of the project is to test accuracy of +VIC to predict LV remodeling and long-term prognosis after revascularization in patients with chronically dysfunctional myocardium. Study population will consist of two groups of patients with stable ischemic LV dysfunction: group A- patients indicated for revascularization (n=200), group B- matched control group treated conservatively (case-control design) (n=100). All patients will be followed for 3 years. Endpoints include: 1) LV remodeling at 6 and 24 months and 2) MACE ...

The purpose of this study was to explore the biobehavioral correlates of adaptive behavior in the context of a standardized laboratory-based mission-relevant challenge (the Soldier Performance and Effective, Adaptable Response Task, SPEAR). Participants were 26 healthy male volunteers (M=34.85 yrs, SD=4.12) with active military duty and leadership experience within the last 5 years (i.e., multiple leadership positions, operational deployments in combat, interactions with civilians and partner nation forces on the battlefield, experience making decisions under fire). The SPEAR task simultaneously engages perception, cognition, and action aspects of human performance demands similar to those encountered in the operational setting. Participants must engage with military-relevant text, visual, and auditory stimuli, interpret new information, and retain the commanders intent in working memory to create a new plan of action for mission success.

Brain science (in particular, the Polyvagal Theory by Stephen Porges) can help us understand why we get stressed in motherhood, and how we can use self-care to calm our nervous systems. The Polyvagal Theory helps explain how our autonomic nervous system responds to stress in motherhood. In particular, it shows how moms move from a calm state of being (ventral vagal), to a fight-or-flight response to stress (sympathetic) to, if necessary, an immobolized freeze response (dorsal vagal), as well as how our nervous systems work to get back to their calm, regulated (ventral vagal) state.

Hello MoA barflies. This is the 2nd in a series of comment I am writing about mental health and neuromodulation techniques.

Befriending the Nervous System: A Beginners Guide to Polyvagal Theory. This listening happens far below awareness and far away from our conscious control. Dr Porges, in understanding that this is not awareness that comes with perception, coined the term neuroception to describe the way our autonomic nervous system scans for cues of safety, danger and life-threat without involving the thinking parts of our brain. Because we humans are meaning-making beings, what begins as wordless experiencing of neuroception drives the creation of a story that shapes our daily living.. The Autonomic Nervous System. The ANS is made up of two main branches, the sympathetic and the parasympathetic and responds to signals and sensations via three pathways, each with a characteristic pattern of response. Through each of these patterns we react in service of survival.. The SYMPATHETIC BRANCH is found in the middle part of the spinal cord and represents the pathway that prepares for ACTION. It responds to cues of ...
