Rapid declines in systolic blood pressure are associated with an increase in pulse transit time. [PDF]
PLoS ONE, 2020 BackgroundThe correlation between pulse transit time and blood pressure has been proposed as a route to measure continuous non-invasive blood pressure. We investigated whether pulse transit time trends could model blood pressure trends during episodes of

Clinical Epidemiology and Global Health, 2021 Introduction: Pulse wave velocity (PWV) is an indicator of arterial stiffness and one of the prognostic tools in clinical practice. We compared the finger photo pulse plethysmography (PPG) module with the Mobil-O-Graph for assessment of PWV. Material and

PULSE TRANSIT TIME - RELIABLE MARKER FOR SLEEP DISTURBANCES AMONG ATHLETES [PDF]
Journal of Applied Sports Sciences, 2019 Sleep is essential for everyone and is important for the normal human functioning. Lack of sleep, called sleep deprivation, is a condition leading to poor sports training and achievements. Different factors contribute to sleep deprivation among athletes.

Medicine in Novel Technology and Devices, 2023 Pulse transit time (PTT) and pulse arrival time (PAT) are explored using multiple sensors connected to the human body. Pulse wave velocity (PWV) is indirectly computed using PTT. We conducted a study using ECG, Pressure, and PPG sensor to capture the PAT

Pulse Arrival Time - A Sensitive Vital Parameter for the Detection of Mental Stress
Current Directions in Biomedical Engineering, 2021 Mental stress triggers positive inotropic and chronotropic effects as well as peripheral vasoconstriction. This alters the pulse arrival time (PAT), the duration between electrical excitation of the ventricles and arrival of the pulse wave in the ...

Pulse transit time in patients with sleep-disordered breathing
The Egyptian Journal of Bronchology, 2018 Background Pulse transit time (PTT) represents a noninvasive marker of sleep fragmentation in patients with obstructive sleep apnea–hypopnea syndrome (OSAHS).
