Difficulties in the measurement of pulse-wave velocity [PDF]
American Heart Journal, 1958 The methods employed in the measuring of pulse-wave velocity are subject to gross error because of alinearity and frequency distortion resulting from low-resonance frequencies of instrumentation and arterial segment and extraneous tissue interference.

On-chip laser Doppler vibrometer for arterial pulse wave velocity measurement [PDF]
, 2013 Pulse wave velocity (PWV) is an important marker for cardiovascular risk. The Laser Doppler vibrometry has been suggested as a potential technique to measure the local carotid PWV by measuring the transit time of the pulse wave between two locations ...

Ultrashort Pulse Detection and Response Time Analysis Using Plasma-wave Terahertz Field Effect Transistors [PDF]
, 2020 We report on the response characteristics of plasmonic terahertz field-effect transistors (TeraFETs) fed with femtosecond and picosecond pulses. Varying the pulse width (tpw) from 10-15 s to 10-10 s under a constant input power condition revealed two distinctive pulse detection modes.

Novel Methods for Pulse Wave Velocity Measurement [PDF]
Journal of Medical and Biological Engineering, 2015 The great incidence of cardiovascular (CV) diseases in the world spurs the search for new solutions to enable an early detection of pathological processes and provides more precise diagnosis based in multi-parameters assessment. The pulse wave velocity (PWV) is considered one of the most important clinical parameters for evaluate the CV risk, vascular ...

P6.01 IMPLANTABLE PULSE WAVE VELOCITY SENSOR
Artery Research, 2013 In case of vascular weakness or thrombosis stents are implanted and brace vessels from the inside to assure the proper blood flow. A widespread method to monitor the state of blood vessels in terms of their stiffness and diameter is to measure the pulse ...

Pulse wave analysis and pulse wave velocity techniques: are they ready for the clinic? [PDF]
Hypertension Research, 2010 interestingly describe animportant factor when arterial stiffness is clini-cally assessed: subject’s body position. Althoughthis is an important question, especially ifwe want to bring this research tool to the clinicin a regular basis, there are several other factorsthat should be considered.
