Photoplethysmography is a key sensing technology which is used in wearable devices such
as smartwatches and fitness trackers. Currently, photoplethysmography sensors are used to …

Photoplethysmography is an optical technique that produces a wealth of information about
cardiovascular health. Therefore, the technology has become an integral part of personal …

Pulse rate variability (PRV) describes the changes in pulse rate through time, when
measured using pulsatile signals such as photoplethysmograms (PPG). PRV has been used …

Over the past decades, hemodynamics simulators have steadily evolved and have become
tools of choice for studying cardiovascular systems in-silico. While such tools are routinely …

Heart rate variability (HRV) can be used as an effective indicator for the maturity of the
neonatal autonomic nervous system (ANS) and some acute neonatal diseases (eg …

Background and Objective ECG-based heart rate variability (HRV), and more recently,
optical pulse rate variability (PRV) analysis used in wearables are non-invasive tools of …

Sample entropy is an effective nonlinear index for analyzing pulse rate variability (PRV)
signal, but it has problems with a large amount of calculation and time consumption …

We propose for the first time a method for extracting the instantaneous phases of respiration
from the signal of a photoplethysmogram (PPG). In addition to the instantaneous phases of …

The formation and changes of the pulse wave are affected by the functional status of the
heart, blood, and arterial vessels. The pulse signal covers pathological information in the …

Introduction: Pulse rate variability (PRV) refers to the changes in pulse rate through time and
is extracted from pulsatile signals such as the photoplethysmogram (PPG). Although PRV …
