Arterial pulse transit time evaluation by peripheral pulse wave measurement

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. For verification this assumption modeling and five veloergonometric test was done. The results showed significant PTT and VIR correlation: –93.4±5.6. Difference between mean values was ±0.1 and dispersion of VIR was less then PTT. New indices able to change PTT have been proposed. This method has powerful perspective for wearable arterial stiffness monitoring devices realization
