电阻抗、导纳图是血液容积波的显示。血波是能量的传递,血流是物质的转移,人体的血波以远远大于血流的快速传播,二者不同时更不同步。血液的容积波包含动,静脉波两个方面,它们分別来自心房和心室的舒、缩,两者共同组成一个总阻抗波并受房-室关系的左右。目前普遍只注重微分波且仅用其高度和时间,忽视全貌更不注意与其母图的关系,舍弃大量有用信息,导致分析舍本求末。
Electrical impedance, admittance diagram is the display of blood volume wave. Blood wave is the transfer of energy, blood flow is the transfer of matter, the body’s blood flow is much greater than the rapid spread of blood flow, the two are not synchronized at the same time. The volumetric wave of blood contains two aspects of arterial and venous waves, which come from the atrium and the ventricles respectively, which form a total impedance wave and are affected by the atrio-ventricular relationship. At present, the general focus only on differential waves and only the height and time, ignoring the picture more pay no attention to its relationship with the mother map, give up a lot of useful information, leading to analysis of the demand for this.
