    The velocity of the pulse wave in man in relation to age as measured by the hot-wire sphygmograph. Heart. ; – Google Scholar; 22 Avolio AP, Deng FQ, Li WQ, Luo YF, Huang ZD, Xing LF, O’Rourke MF. Effects of aging on arterial distensibility in populations with high and low prevalence of hypertension: comparison between urban. Pulse wave velocity (PWV) is assessed by measuring transit distance and transit time between two sites in the arterial system and taking their ratio (Fig. ).Transit time is measured by comparing the arrival time of a pressure waveform at two points along a segment of artery that is long enough to allow for accurate measurement of the time delay.

      Pulse wave velocity (PWV) is associated with heart rate variability (HRV) in 24–year-old men. This study of 40–year-old men ranging in moderate-to-vigorous physical activity levels investigated whether (a) PWV is related to spectral HRV, (b) using normalised units for HRV influences that relationship, and (c) HRV predicts PWV when other factors, including age and blood pressure, . The velocity of the pulse wave in man in relation to age as measured by the hot-wire sphygmograph. pulse wave velocity was measured with the SphygmoCor system and one-point carotid pulse wave.

    Methods: Systemic BP was measured by an automated device (Dinamap), while stiffness of the brachioradial arterial segment was assessed by measuring pulse wave velocity (PWV). The birth weight was adjusted for gestational age and expressed as a z score for analysis. Results: The 86 children were studied at a mean (SD) age of () years. Arterial compliance was measured in 70 healthy volunteers, 13 athletes, and 17 patients with coronary artery disease. Magnetic resonance images were acquired at end diastole and end systole.

How well the aorta dampens the pressure from ventricular and arterial pulses can also be detected. Instrumentation for the real-time clinical measurement of pulse wave velocity (PWV) from intra-arterial pressure waveforms is presented.

The time delay between pressure waveforms (obtained from two intra-arterial catheter-mounted transducers 5 cm apart) is calculated by a transputer using multiple comparisons between discrete sections of the waveforms. OBJECTIVES This study was designed to determine noninvasively the age-associated changes in regional mechanical properties in normals using phase-contrast magnetic resonance imaging (PCMRI).

BACKGROUND It has been well documented that there is a progressive increase in aortic pulse wave velocity (PWV) with age. Previously, PWV has been measured at a single aortic location, or has.

Article. Pulse wave velocity (PWV) was measured by means of transcutaneous Doppler techniques.Pulse wave velocity (PWV) is the velocity at which the blood pressure pulse propagates through the circulatory system, usually an artery or a combined length of arteries. PWV is used clinically as a measure of arterial stiffness and can be readily measured non-invasively in humans, with measurement of carotid to femoral PWV (cfPWV) being the recommended method.
