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

Estimation of PTT (Pulse Transit Time) by Multirate Filtering Analysis [PDF]
The Transactions of The Korean Institute of Electrical Engineers, 2013 Multirate filtering process on the biological signals like Electrocardiogram (ECG) and Photoplethysmogram (PPG) can be defined as the digital signal processing algorithm in which the sampling rate varies to omit or interpolate the intermediate values between the sampled data. With this aim, we suggest a new multirate filtering algorithm by deleting the

Calculation and Validation of Continuous Pulse Transit Time Based on Normalized Pulse Wave Velocity
IEEE Access, 2020 Typically, the pulse transit time (PTT) is extracted as a discrete value per heartbeat: it is calculated as the time difference between specific points of the pulse waveforms measured at two different sites.

Pulse Transit Time (PTT) Measurements During Laparoscopic and Open Abdominal Surgery: A Pilot Study in ASA I-II Female Patients [PDF]
The Open Anesthesiology Journal, 2008 Background: The pulse transit time (PTT) is the time interval between the R-wave of the ECG and the appearance of the pulse wave in the periphery during the same cardiac cycle. PTT is influenced by various factors including sympathetic tone and vascular compliance.

PTT-based Contact-less Blood Pressure Measurement using an RGB-Camera
Current Directions in Biomedical Engineering, 2021 Commonly used blood pressure measurement devices have noticeable limitations in accuracy, measuring time, comfort or safety. To overcome these limitations, we developed and tested a surrogate-based, non-invasive blood pressure measurement method using an

Development of tubular cardiovascular phantom system for pulse transit time simulation [PDF]
, 2019 This paper presents on the development of a tubular cardiovascular phantom system to simulate pulse transit time (PTT). The PTT defined as the delay time between two pulses in one cardiac cycle has been shown to be promising method for cuffless ...
