Background: A growing number of wearable devices claim to provide accurate, cheap and
easily applicable heart rate variability (HRV) indices. This is mainly accomplished by using …

Heart rate variability (HRV) is a known risk factor for mortality in both healthy and patient
populations. There are currently no normative data for short‐term measures of HRV. A …

This study was designed to examine the RR interval signal qualities of a Holter device and a
heart rate chest belt monitor at rest and during exercise. Ten healthy individuals completed …

Purpose To assess the validity of RR intervals and short-term heart rate variability (HRV)
data obtained from the Polar V800 heart rate monitor, in comparison to an …

Interoception, the capacity to perceive internal bodily states, is thought to influence cognitive,
affective and interpersonal functioning. It is frequently assessed using the heartbeat …

Heart rate variability (HRV) analysis is a noninvasive tool widely used to assess autonomic
nervous system state. The market for wearable devices that measure the heart rate has …

Background Advancements in wearable technology have provided practitioners and
researchers with the ability to conveniently measure various health and/or fitness indices …

Wearable physiological measurement devices for ambulatory research with novel sensing
technology are introduced with ever increasing frequency, requiring fast, standardized, and …

The first aim of this study was to compare an ambulatory five-lead ECG system with the
commercially available breast belt measuring devices; Polar S810i and Suunto t6, in terms …

Policing is a highly stressful and dangerous profession that involves a complex set of
