Physiological fluid mechanics has been a research area for more than half a century with attempts to develop diagnostic techniques and biomarkers that differentiate between healthy and pathological circulatory states. In arterial hemodynamics, initially, from the 50’s of the 20th century, techniques generally described arterial pressure and velocity waves as sinusoidal wavetrains running into long tubes. These were usefully expanded by the introduction of the impedance analysis in the late 60’s and early 70’s; the technique was borrowed from electrical engineering disciplines, presented arterial resistance, pressure and flow as an electrical circuit and the results were presented in the frequency domain.

生理流体力学研究：前沿研究特刊

半个多世纪以来，生理流体力学一直是一个研究领域，试图开发区分健康和病理循环状态的诊断技术和生物标志物。在动脉血流动力学中，最初，从 20 世纪 50 年代开始，技术通常将动脉压力和速度波描述为运行在长管中的正弦波列。在 60 年代末和 70 年代初引入阻抗分析后，这些功能得到了有益的扩展。该技术借鉴了电气工程学科，将动脉阻力、压力和流量作为电路呈现，结果在频域中呈现。
