利用心阻抗图测定心脏功能的无创性方法已被多数国内外学者所公认,但这一方法在理论与实际测量中尚存在许多不完善的地方。本研究利用恒流式阻抗仪和恒压式导纳仪对新疆地区不同海拔高度和不同民族共914人进行了心导纳图和心阻抗图的测定,以探讨阻抗法与导纳法在测定心脏功能方面的区别与相关性。 Noninvasive methods for the determination of cardiac function using cardiac impedance maps have been well accepted by most scholars at home and abroad, but there are still many imperfections in the theoretical and practical measurement of this method. In this study, the cardiac admittance and cardiac impedance maps were measured in 914 people of different ethnic groups and different altitudes in Xinjiang using constant current impedance meter and constant pressure admittance meter to discuss the relationship between impedance method and admittance method in the determination of Differences and Correlations in Cardiac Function.
