Abstract
Transthoracic electrical impedance Z consists of a constant baseline component Zo and the time variable component .DELTA.Z such that Z = Zo + .DELTA.Z. The 1st time derivative of Z has a negative peak and a magnitude (dZ/dt)min. In 170 volunteers (dZ/dt)min was measured by cardiography: [dZ/dt] was a function of the constant baseline component Zo. At least a part of the difference of the magnitudes of (dZ/dt)min on Zo must be considered.This publication has 1 reference indexed in Scilit:
