Pulse Wave Analysis [PDF]

open access: yesHypertension, 2011
Cardiovascular refers to the Cardio (heart) and vascular (blood vessels). The system has two major functional parts: central circulation system and systemic circulation system. Central circulation includes the pulmonary circulation and the heart from where the pulse wave is generated. Systemic circulation is the path that the blood goes from and to the

Pulse wave analysis. [PDF]

open access: yesBritish Journal of Clinical Pharmacology, 1996
‘Since the information which the pulse affords is of so great importance, and so often consulted, surely it must be to our advantage to appreciate fully all it tells us, and to draw from it every detail that it is capable of imparting’ F.A. Mahomed 1872 [1] It is now possible to generate the ascending aortic pressure wave from the arterial pressure ...

Machine Learning-Based Pulse Wave Analysis for Early Detection of Abdominal Aortic Aneurysms Using In Silico Pulse Waves

open access: yesSymmetry, 2021
An abdominal aortic aneurysm (AAA) is usually asymptomatic until rupture, which is associated with extremely high mortality. Consequently, the early detection of AAAs is of paramount importance in reducing mortality; however, most AAAs are detected by ...

Blood Pressure Estimation by Photoplethysmogram Decomposition into Hyperbolic Secant Waves

open access: yesApplied Sciences, 2022
Photoplethysmographic (PPG) pulses contain information about cardiovascular parameters. In particular, blood pressure can be estimated using PPG pulse decomposition analysis, which assumes that a PPG pulse is composed of the original heart ejection blood

Hemodynamic Data Analysis and Site of Measurement in Children and Adolescents

open access: yesArtery Research, 2020
Pulse wave velocity is a method of functional vascular evaluation. The gold standard is the carotid-femoral pulse wave velocity measurement. However, the software allows measurement among radial, carotid and femoral artery.
