A radio frequency 5 (RF) generator (36) has second active and indifferent outputs and is configured to generate RF electrical energy of a predetermined frequency between the second active and indifferent outputs for application to the heart of the subject simultaneously with the pacing pulses. A filter (40) includes a first branch (54) connected between the first and second active outputs and a second branch connected 10 between the first and second indifferent outputs, each of the first and second branches (54, 56) including one or more notch filters (60) having a high impedance in a vicinity of the frequency of the RF electrical energy. 0 1/06/09,va 18005 speci, 142/4 7/ C 2 c C 2 CCD C).
