An impedance cardiography – simple, noninvasive method for determination of cardiac stroke volume. Part 1. Methodical basis Review article
Main Article Content
Abstract
The foundations of the impedance cardiography as a noninvasive method for continuous determination of stroke volume, cardiac output and systolic time intervals (pre-ejection period and left ventricular ejection time) were described. The genesis of the signal, the used arithmetic formulas for SV evaluation and limitation of the method were presented.
