Parents' ability to regulate their emotions is essential to providing supportive caregiving behaviours when their child is in pain. Extant research focuses on parent self-reported experience or observable behavioural responses. Physiological responding, such as heart rate (HR) and heart rate variability (HRV), is critical to the experience and regulation of emotions and provides a complementary...

It is established that the instantaneous heart rate (HR) of healthy humans keeps on changing. Analysis of heart rate variability (HRV) has become a popular non invasive tool for assessing the activities of autonomic nervous system. Depressed HRV has been found in several disorders, like diabetes mellitus (DM) and coronary artery disease, characterised by autonomic nervous dysfunction. A new tec...

Objectives: Heart rate variability (HRV) has been used to assess sympathetic and parasympathetic modulation of heart rate. Chronic stress relates to reduced HRV. Malocclusion has effects on quality of life, which can lead to chronic stress. Therefore, we hypothesized that malocclusion, as chronic stress, may contribute to reduced HRV. The aim of this study was to investigate the relationship be...

Heart rate variability (HRV) is often analyzed using short-term studies: 5-min and 2-min heart rate datasets. The correlation between the two data segments in HRV analysis has not been well understood. This paper reports a statistical comparison of the results of HRV spectral analysis for the 5-minute versus 2-minute short-term studies using photoplethysmogram (PPG). Twenty repeat measurements ...

The autonomic nervous system plays a central role in regulation of host defense and in physiological responses to sepsis, including changes in heart rate and heart rate variability. The cholinergic anti-inflammatory response, whereby infection triggers vagal efferent signals that dampen production of proinflammatory cytokines, would be predicted to result in increased vagal signaling to the hea...

There is a limited number of studies on heart rate variability (HRV) dynamics immediately after exercise. It is well-known that the electrocardiogram is a non-invasive method that can be used to measure heart rate variability (HRV) at rest and after exercise. Photoplethysmogram (PPG) signals also reflect the cardiac rhythm since the mechanical activity of the heart is coupled to its electrical ...

Correspondence to: Dr. Victor Dan Moga, e-mail: [email protected]. SUMMARY: Despite the development of pharmacological therapy and/or device therapy, atrial fibrillation remains a leading cause for morbidity and mortality. Heart rate variability (HRV) is studied only in the presence of sinus rhythm. Currently, three different categories of methods in HRV analysis are being used; the time do...

The number of publications investigating heart rate variability (HRV) in psychiatry and the behavioral sciences has increased markedly in the last decade. In addition to the significant debates surrounding ideal methods to collect and interpret measures of HRV, standardized reporting of methodology in this field is lacking. Commonly cited recommendations were designed well before recent calls t...
