摘要
Disclosed herein are in vivo non-invasive methods and devices for the measurement of the hemodynamic parameters, such as blood pressure, cardiac output, stroke volume and vascular tone, of a subject, and the mechanical anelastic in vivo properties of the subject's arterial blood vessels. An exemplary method requires obtaining the peripheral pulse volume waveform (PVW), the peripheral pulse pressure waveform (PPW), and the peripheral pulse velocity waveform (PUW) from the same artery; calculating the time phase shift between the PPW and PVW, and the plot of pulse pressure versus pulse volume: and determining the blood pressures and power law components of the anelastic model from the waveforms PPW and PVW, the cardiac output from the waveforms PPW and PUW, and the quality factor of the artery based upon the calculations. The disclosed methods and devices can be used to diagnose and treat cardiovascular disease in a subject in need thereof.
