Assessment of pulse wave velocity
Artery Research, 2008 Measurement of pulse wave velocity is of increasing importance for assessment of arterial stiffness and risk evaluation. Different techniques are available, based either on pressure, distension or Doppler waveforms.

Review of the identification of near-fault velocity pulse-like strong ground motions
地球与行星物理论评, 2023 Strong pulse-like ground motions have caused extensive damage to many engineering structures and are one of the main factors influencing earthquake damage in near-fault regions.

Biomedicines, 2021 Primary aldosteronism (PA) is associated with higher arterial stiffness compared to essential hypertension (EH). However, few studies have compared different pulse wave velocity (PWV) parameters to detect aldosterone-induced arterial stiffness.

Dizhen xuebao, 2018 为了研究速度脉冲型地震动的最强速度脉冲方向分量与垂直或平行断层方向分量之间的特性差异，本文采用多分量速度脉冲识别方法从NGA-West2强震动数据库的236组近断层地震动速度脉冲记录中提取出最强速度脉冲方向分量，对其脉冲参数随震级MW和断层距R变化的统计关系式进行了回归分析，并对比了最强速度脉冲方向分量与垂直或平行断层方向分量之间的特性差异。研究结果表明：当R＜30 km时，最强速度脉冲方向分量的脉冲幅值预测值较垂直或平行断层方向分量的预测值大，而当R＞30 km时，两种分量的脉冲幅值预测值相差不大 ...

Pulse Wave Velocity in Postmenopausal Women [PDF]
Pulse, 2013 Cardiovascular disease (CVD) and osteoporosis are major causes of morbidity and mortality in postmenopausal women. The relationship between atherosclerosis and osteoporosis has been established by studies of the underlying pathophysiological mechanisms and biochemical pathways that seem to overlap in many places. Pulse wave velocity (PWV) is one of the

Physiological Reports, 2021 We hypothesized that volume changes during 48‐h are associated with different circadian patterns of arterial stiffness on non‐dialysis day compared to dialysis day and that the night‐time increase of arterial stiffness is associated with higher mortality.

Pulse wave velocity in the carotid artery [PDF]
2008 IEEE Ultrasonics Symposium, 2008 The pulse wave velocity (PWV) in the carotid artery (CA) has been estimated based on ultrasound data collected by the experimental scanner RASMUS at DTU. Data is collected from one test subject using a frame rate (FR) of 4000 Hz. The influence of FRs is also investigated.
