Abstract :
The new ambulatory monitoring, universal 4-channel recorder enabling simultaneous collection of ECG and central haemodynamics signals was constructed. The system is based on 80C552 family controller with built-in analogue to digital converters and 20 MB PCMCIA (type II) FLASH MEMORY CARD is used as a data storage. The communication with the system is performed via specialised keys and the small, built-in LCD. We design and constructed the miniaturised, tetrapolar, current impedance cardiography device with built-in one channel of ECG, which was applied as a detector of the central haemodynamics signals. The device enables the full disclosure of the collected data, which could be used in off-line, beat-to-beat evaluation of cardiac output, stroke volume, ejection time, pre-ejection period and heart rate.
