Various non-electrocardiogram (ECG) based methods are considered reliable sources of
heart rate variability (HRV) measurement. However, the ultra-short recording of a femoral …

Introduction Combat-related traumatic injury (CRTI) has been linked to an increased
cardiovascular disease (CVD) risk. The long-term impact of CRTI on heart rate variability …

In this study, the comparative precision of carotid versus femoral arterial waveforms to
measure ultra-short term heart rate variability (HRVUST) following traumatic injury was …

Purpose: Heart rate variability (HRV) has been used for decades as a tool for measuring
systemic health through the autonomic nervous system (ANS). The purpose of this paper …

Background: Short-term (5 min) heart rate variability (HRV) analysis is widely used in
assessing autonomic nervous system activity during exercise. While shortening the HRV …

Pulse rate variability (PRV) assesses the changes in pulse rate through time when pulse
rate is extracted from pulsatile signals such as the photoplethysmogram (PPG). PRV has …

Aim Assess the cardiac autonomic modulation during and after lower limbs resistance
exercise (RE) in elderly compared to young. Methods Fifteen elderly (66±5 years) and 15 …

In this paper, we propose the use of recurrent neural networks (RNNs) for artifact correction
and analysis of heart rate variability (HRV) data. HRV can be a valuable metric for …

Objectives: Ultra-short heart rate variability (HRV) metrics represent autonomic tone
parameters derived using small epochs of interbeat interval data. These measures have …

Introduction: Heart rate variability (HRV) is determined by the variation of consecutive
cardiac electrical excitations, usually from RR intervals of an EKG. The sequence of intervals …
