Abstract

The system is used for external examination and monitoring of the circulating dynamics of patients. It uses a system of intrnal catheter probes and two external electrodes with one or more sensors of external type for observation of heart phenomena with external electrical devices to produce electrocardiogram type recordings. It has a HF constant current generator connected to the two external body electrodes to investigate the circulatory dynamics. The electrode are attached diagonally to the patient(P) thorax. The electrocardiogram channel and conductivity value cardiogram cahnnel are fed by the material body electrodes (6-11) of the catheter probe (1).
