Multi agent system for estimation of cardiovascular parameters [PDF]

open access: yes, 2005
Many cardiovascular diseases can be avoided by continuous monitoring cardiovascular parameters. Heart rate, electrocardiogram, blood pressure and pulse wave velocity are the most important and popular cardiovascular parameters.

A Neural Network Model for Estimating the Heart Rate Response to Constant Intensity Exercises

open access: yesSignals, 2021
Estimating the heart rate (HR) response to exercises of a given intensity without the need of direct measurement is an open problem of great interest. We propose here a model that can estimate the heart rate response to exercise of constant intensity and

Heart Rate Detection and Classification from Speech Spectral Features Using Machine Learning

open access: yesArchives of Acoustics, 2021
Measurement of vital signs of the human body such as heart rate, blood pressure, body temperature and respiratory rate is an important part of diagnosing medical conditions and these are usually measured using medical equipment. In this paper, we propose

Aerobic Energy Expenditure and Intensity Prediction During a Specific Circuit Weight Training: a Pilot Study [PDF]

open access: yes, 2010
During circuit weight training (CWT), workloads, index of intensity as well as estimation of energy expenditure (EE) have been under estimated. The aim of this study was to describe and evaluate physiological variables and gender related differences ...

Compressive-Sensing-based Multidimensional Doppler signal analysis for fetal activity monitoring [PDF]

open access: yes, 2014
International audienceFetal activity monitoring is an important part of monitoring at-risk pregnancies and labor. Fetal activity parameters (FAP) consist of fetal heart rate (FHR), fetal movements (FM) rate, fetal tone, fetal breathing (FB) and movement.

PPG Derived Heart Rate Estimation During Intensive Physical Exercise

open access: yesIEEE Access, 2019
Accurate and reliable estimation of heart rate (HR) from photoplethysmographic (PPG) signals during moderate and vigorous physical activities is a challenging task, since intense motion artifacts can easily disguise the true HR.

HEAR: Approach for Heartbeat Monitoring with Body Movement Compensation by IR-UWB Radar [PDF]

open access: yes, 2018
Further applications of impulse radio ultra-wideband radar in mobile health are hindered by the difficulty in extracting such vital signals as heartbeats from moving targets. Although the empirical mode decomposition based method is applied in recovering
