[Cardiac trans-esophageal pacing: significance of systemic damping of artifacts from stimulating impulses for ECG trace recordings recorded from a pacing trans-esophageal electrode. III].
Utilization of diagnostic abilities of the cardiac trans-esophageal pacing is related to necessity of obtaining the readable and stable ecg tracing from a pacing electrode. For that reason to evaluate the value of an electronic artifact suppression circuit of a pacing impulse from oesophageal ecg recording authors compared quality of obtained recordings using a new method with a traditional one. Trans-esophageal cardiac pacemaker SP-5 made by OBR, Temed, Zabrze was used. Atria and ventricles were stimulated using a constant pacing cycle length and a single programmable impulse. In 58 persons ecg transoesophageal recordings were compared during atrial pacing, and in 45 during ventricular one. Quality of obtained ecg recordings was estimated using 4-degree scale of which first three degrees comprised recordings the esophageal pacing electrode by a traditional method were unfit for diagnostic interpretation. As opposed to the pacing electrode allowed to obtain recordings with quality of which was suitable for diagnostic interpretation in all patients. Obtained results indicate on, thanks to the new recording circuit, existence of conditions to substantial extension of diagnostic abilities of transoesophageal cardiac pacing.
