The paper presents the results of study on optimizing of ECG-signal filtration in case of ECG recordings during noninvasive transesophageal and transcutaneous diagnostic and therapeutic heart stimulation. The study comprised an effectiveness of hardware-software noninvasive stimulator artifact elimination system applied in electrocardiograph DEK-631 (ITAM – Zabrze) as well as the effectiveness of analogous circuit of spike artefacts elimination applied in recording channel of diagnostic cardiostimulator SP-5plus (ITAM). The influence of filtration on a quality of ECG signal recorded and a possibility of drawing the objective diagnostic conclusions have been assessed. Analogous artifact elimination system (AES) contained in SP-5plus ensured obtaining of good quality of ECG recording during noninvasive stimulation of atria and ventricles in all diagnostic and therapeutic applications.
