Robust contactless pulse transit time estimation based on signal quality metric [PDF]
, 2020 The pulse transit time (PTT) can provide valuable insight into cardiovascular health, specifically regarding arterial stiffness and blood pressure. Traditionally, PTT is derived by calculating the time difference between two photoplethysmography (PPG ...

Artifacts in pulse transit time measurements using standard patient monitoring equipment.
PLoS ONE, 2019 ObjectivePulse transit time (PTT) refers to the time it takes a pulse wave to travel between two arterial sites. PTT can be estimated, amongst others, using the electrocardiogram (ECG) and photoplethysmogram (PPG). Because we observed a sawtooth artifact

Pulse arrival time as a surrogate of blood pressure
Scientific Reports, 2021 Various models have been proposed for the estimation of blood pressure (BP) from pulse transit time (PTT). PTT is defined as the time delay of the pressure wave, produced by left ventricular contraction, measured between a proximal and a distal site ...

Long-term Blood Pressure Prediction with Deep Recurrent Neural Networks
, 2018 Existing methods for arterial blood pressure (BP) estimation directly map the input physiological signals to output BP values without explicitly modeling the underlying temporal dependencies in BP dynamics.

Arterial pulse transit time evaluation by peripheral pulse wave measurement [PDF]
, 2013 Arterial pulse transit time (PTT) is a simple noninvasive diagnostic tool. However it is still requiring two processes ECG and photoplethysmogram to be measured.

Cuff-less continuous blood pressure monitoring system using pulse transit time techniques [PDF]
, 2016 This paper describes the development of a continuous cuff-less blood pressure system based on the pulse transit time (PTT) technique. In this study, PTT is defined by two different approaches denoted as PTT1 and PTT2.

Aortic frequency response determination via bioimpedance plethysmography
, 2019 Objective: Arterial stiffness is an important marker to predict cardio vascular events. Common measurement techniques to determine the condition of the aorta are limited to the acquisition of the arterial pulse wave at the extremities.

Hybrid Optical Unobtrusive Blood Pressure Measurements
Sensors, 2017 Blood pressure (BP) is critical in diagnosing certain cardiovascular diseases such as hypertension. Some previous studies have proved that BP can be estimated by pulse transit time (PTT) calculated by a pair of photoplethysmography (PPG) signals at two ...
