[Determination of the location of the endocardiac electrode in the right ventricular cavity by the configuration of an artificial ventricular ECG complex].
Two patient groups (in all 31 subjects) underwent endocardial heart stimulation. While studying the first group (18 subjects) during the electric heart stimulation from various points of the right ventricle endocardium, the regularity of the change in the direction of artificial ventricular complex vector was revealed when the stimulating electrode was dislocated into the influx and efflux tracts of the right ventricle. While studying the second group (13 patients) in the dislocation of the temporary endocardial electrode the ECG and roentgenographic data were compared, and the diagnostic value of the electrocardiographic method was established.
