[A noninvasive method for radial pulse-wave velocity and the determinants of pulse-wave velocity].

Sheng wu yi xue gong cheng xue za zhi = Journal of biomedical engineering = Shengwu yixue gongchengxue zazhi, 2003
An effective experimental method has been proposed and used to determine the pulse-wave velocity (PWV) of 257 radial pulse signals. Experimental results show that, compared with the normal pulse, the wiry pulse has an increased PWV(P < 0.01 or P < 0.05), the thready pulse has a decreased PWV(P < 0.05), but the PWV of the smooth pulse is not ...

Central pulse wave velocity is responsible for increased brachial‐ankle pulse wave velocity in subclinical hypothyroidism

Clinical Endocrinology, 2007
SummaryObjective  Subclinical hypothyroidism affects 5–15% of the general population, and is associated with increased morbidity from cardiovascular disease. We recently reported a significant increase in brachial‐ankle pulse wave velocity (baPWV), a parameter of arterial stiffening and an independent predictor for the presence of cardiovascular ...

[Measurement of the velocity of the pulse wave].

Bollettino della Societa italiana di biologia sperimentale, 1980
Pulse wave transmission rate has been measured "in vivo" in 6 male anaesthetized Wistar rats, by means of cannulae, inserted both in carotid and femoral arteries. The measure has been done by calculating the time delay of several corresponding levels in the two pressure pulses: at the foot, during the ascending phase, at the peak.

Pulse wave velocity and hypertension

1987
Of the many factors implicated in the genesis and maintenance of elevated arterial pressure, the pulsatile function of the arterial system has received little attention in comparison to other cardiovascular related phenomena such as increase in peripheral resistance, regulation of cardiac output, the role of the autonomic nervous system, glomerular ...

[Pulse wave velocity(PWV)].

Nihon rinsho. Japanese journal of clinical medicine, 2004
Brachial-ankle pulse wave velocity(baPWV) is a noninvasive and simple method of measuring arterial stiffness and an independent predictor of cardiovascular mortality in some lifestyle-related diseases. We evaluated that baPWV is well correlated with many atherosclerotic risk factors including abdominal visceral obesity and HOMA, and that the ...

Arterial pulse wave velocity

2003
The pulse wave generated by the left ventricular myocardium contraction and blood ejection is propagated throughout the arterial tree at a speed determined by the elastic and geometric properties of arterial wall and the blood density. This velocity along the aorta or along the arteries of the forearm can be measured by using two ultrasound or strain ...

[Arteriosclerosis and pulse wave velocity].

Nihon rinsho. Japanese journal of clinical medicine, 2004
Impairment of the arterial compliance or loss of Windkessel effect of elastic arteries causes increased afterload to the heart and increased pulsatile flow to the peripheral vasculatures. The former induces left ventricular hypertrophy or dysfunction and the latter induces small vessel damage or end organ dysfunction.

Pulse Wave Velocity Techniques

2019
Recently, pulse wave velocity (PWV), or its reciprocal pulse transit time (PTT), has been intensively investigated as a promising technique for continuous, cuffless, and noninvasive blood pressure (BP) monitoring. BP is mathematically derived through PTT, or the “time delay” in propagation of pressure waves in the vascular system, which can be easily ...

Instruments for Pulse Wave Analysis and Measurement of Pulse Wave Velocity

2012
Over the last few years, a lot of new instruments for pulse wave analysis or measurement of pulse wave velocity have been launched onto the market. It seems that their main aim is to supply operator-independent devices, which can perform faster, while the accuracy of the measurement or the scientific soundness of the algorithms used are of secondary ...
