Measurement of pulse transit time using ultra-wideband radar

, 2021
BACKGROUND: The pulse transit time is an important factor that can be used to estimate the blood pressure indirectly. In many studies, pressures in the artery near and far from the heart are measured or the electrocardiogram and photoplethysmography are ...

P.37 An Assessment of Potential Sources of Error that May Arise in the Measurement of Carotid-Femoral Pulse Wave Velocity

Artery Research, 2020
Objectives: Carotid-femoral pulse wave velocity (cfPWV) approximates aortic stiffness and is a predictor of cardiovascular events. Despite the literature highlighting the clinical relevance of cfPWV, there is minimal integration of this parameter in ...

Artefacts in continuous overnight blood pressure assessment based on pulse transit time

Current Directions in Biomedical Engineering, 2021
Continuous non-invasive blood pressure measurements bear a high potential. Particular in Somnology they allow to derive comfortably the systolic and diastolic blood pressure from an electrocardiogram and a synchronous photoplethysmogram without sleep ...

Development of Real-Time Cuffless Blood Pressure Measurement Systems with ECG Electrodes and a Microphone Using Pulse Transit Time (PTT)

Sensors, 2023
Research has shown that pulse transit time (PTT), which is the time delay between the electrocardiogram (ECG) signal and the signal from a photoplethysmogram (PPG) sensor, can be used to estimate systolic blood pressure (SBP) and diastolic blood pressure

Continuous Estimation of Blood Pressure by Utilizing Seismocardiogram Signal Features in Relation to Electrocardiogram

Biosensors
There is an ongoing search for a reliable and continuous method of noninvasive blood pressure (BP) tracking. In this study, we investigate the feasibility of utilizing seismocardiogram (SCG) signals, i.e., chest motion caused by cardiac activity, for ...

Pulse transmission time and amplitude of digital pulse wave determined by fingertip plethysmography as a surrogate marker of brachial artery flowmediated dilatation

Journal of the Pakistan Medical Association
Objectives: To assess the changes in blood vessel stiffness and digital pulse wave amplitude because of flowmediated dilatation, and to explore how these two variables change when endothelial dysfunction is experimentally induced.

Observational Study of Pulse Transit Time in Children With Sleep Disordered Breathing

Frontiers in Neurology, 2020
Background: Pulse transit time (PTT) is a non-invasive measure of arousals and respiratory effort for which we aim to identify threshold values that detect sleep disordered breathing (SDB) in children.
