A computerized bioelectrical cardiac monitor.
The use of a micro-computer improves the performance of an impedance cardiograph. The impedance signals and the ECG are real-time processed and four analog signals are displayed on the screen. A beat-to-beat estimation of cardiac output and several indexes are computed and displayed. User's interface is by interactive screen menus. Some facilities permit data identification, storage and post-processing. The software has been designed in such a way as to be adaptable to each specific application and to enable the development of new routines for cardiac signal processing. The signals recorded in healthy patients are in agreement with the results of other similar studies.
