A total of 586 sows were studied by means of telemetric electrocardiography, 199 of them (33.96%) showed the presence of the pathological Q wave in their ECG. In 56 of them RC complexes were registered. Sows were kept in individual pens during fertilization and furrowing. They were moved to a common pen after positive pregnancy tests. The additional ventricular contractions registered in ECG were of the Q/r complex type. These contractions were marked as RC complexes and were not followed by a compensatory pause. The reasons for their presence were not clarified.

Key words: ECG, RC complexes, ECG telemetry
