电阻图又称血流图,是一种无创性电阻抗式容积描记,用来探查心动周期中机体各脏器及组织血管容积变化的生物物理方法。它能反映脏器的体液和血流动力学变化、循环机能状态、血液供应强度、以及血管机能状态等,因而用于某些疾病的 Resistance map, also known as blood flow map, is a non-invasive electrical impedance plethysmography, used to explore the body’s organs and cardiac tissue volume changes in vascular biophysical methods. It can reflect organ fluid and hemodynamic changes, circulatory status, blood supply intensity, and vascular function status, which for some diseases
