Pulse transit time as an index of vascular reactivity
Pulse transit time (PTT) is a non-invasive method for measuring arterial compliance and stiffness, which are excellent predictors of cardiovascular disease. This study aims to determine whether PTT can be used to precisely monitor vascular reactivity in

Venous Pulse Transit Time in Normal Pregnancy and Preeclampsia [PDF]
Uncomplicated pregnancies (n = 16) were evaluated longitudinally and compared to early- (n = 12) and late-onset (n = 14) preeclampsia patients, assessed once at diagnosis. Pulse transit time (PTT), equivalent to pulse wave velocity, was measured as the time interval between corresponding characteristics of electrocardiography and Doppler waves ...

An Experimental Analysis of Discrimination of Pulse Transit Time
The present study attempted to determine if individuals could be trained to discriminate changes in their own pulse transit time, an indirect estimate of relative (systolic) blood pressure. A single-subject ABAB reversal-reinstatement design was used in an experimental analysis of the effects of feedback on pulse transit time discrimination in a ...

Arterial pulse transit time evaluation by peripheral pulse wave measurement [PDF]
Arterial pulse transit time (PTT) is a simple noninvasive diagnostic tool. However it is still requiring two processes ECG and photoplethysmogram to be measured. Object of this investigation is verifying hypothesis about velocity of the initial rise in peripheral pulse waveform (VIR) and arterial pulse transit time correlation.

Automatic Seizure Detection Using the Pulse Transit Time
Documentation of epileptic seizures plays an essential role in planning medical therapy. Solutions for automated epileptic seizure detection can help improve the current problem of incomplete and erroneous manual documentation of epileptic seizures. In recent years, a number of wearable sensors have been tested for this purpose.

Difference in Pulse Arrival Time at Forehead and at Finger as a Surrogate of Pulse Transit Time
Pulse transit time (PTT) difference (PTTD) to the forehead and finger dynamics are compared to pulse arrival time towards the finger (PATF) dynamics during a tilt table test. Two frequency bands, where different physiological information is expected, are analyzed: low frequency (LF) influenced by both sympathetic and parasympathetic activity, and high ...
