摘要
Disclosed herein are in vivo non-invasive methods and devices for the measurement of the hemodynamic parameters and aortic valve conformance and compliance in a subject. The method requires measuring the peripheral pulse volume waveform (PVW), the peripheral pulse pressure waveform (PPW), and the peripheral pulse velocity waveform (PUW) from the same artery using a non-invasive device. The waveforms PPW and PUW are used to calculate the waveform dPdU which is used to determine aortic valve ejection volume, closure volume, and quality factor, as well as stroke volume and cardiac output. The disclosed methods and devices are useful in the diagnosis and treatment of aortic valve disease, disorders, and dysfunction.
