Objective To research the information of blood vessels made by high-frequency vibration flow artificial heart,and to clear the frequency characteristics of the blood vessels.Methods Surgery was conducted on 11 healthy adult goats to let their blood flow from the left apexes to the main aorta descendens by using high frequency vibration flow artificial heart.A point of vascular impedance was got without mathematical model,while a curve of vascular dynamic impedance was simulated by using measured data with mathematical model.Results Vascular dynamic impedance curves in different states were successfully mapped.Points without mathematical model fitted the curves well.Conclusion The vascular dynamic impedance calculated by the mathematical model completely shows the dynamic characteristics of blood vessels as well as the whole curve.
