随着心脏内科和心脏外科研究飞速进展,无创的和有创的心功能检测技术的研究,也越来越多的受到医学界的重视,前人用多导记录仪、超声、胸阻抗图等无创方法从不同的角度进行了探索,用心导管技术从动力学角度作了卓有成效的研究,由于心脏的解剖结构和它的生理作用,是一个推动血液循环流动的生物血泵,对于这种血泵的工作状态,从生理学的角度称它为心功能,从循环动力学角度称它为心脏动力学,
With the rapid progress in research in cardiology and cardiac surgery, non-invasive and invasive researches on cardiac function testing have also received more and more attention from the medical community. Predecessors use multi-lead recorders, ultrasound, thoracic impedance maps, etc. Non-invasive methods have been explored from different perspectives, and cardiac catheterization has been used to make effective researches from a dynamic point of view. Due to the anatomical structure of the heart and its physiological effects, it is a bio-blood pump that promotes blood circulation, for this blood pump. The working state is called physiological function from the physiological point of view, and it is called cardiac dynamics from the perspective of cyclic dynamics.
