A pacemaker system (100) includes a pacemaker device (160), cardiac leads (120) and (150), guide catheter (110), an ultrasound transmitter (133) and an ultrasound receiver (130). Cardiac lead (150) is implanted in the right atrium (RA) (82) and includes an electrode (152) at its distal end that is actively fixed into location (102) of the right atrium (82). Electrode (152) is used for pacing of the RA. Cardiac lead (120) is implanted in the right ventricle (RV) 84 and includes two separate electrodes. A first electrode (140) is actively fixed into location (101) close to the apex (98) of the right ventricle (84) and is used for pacing, sensing and/or defibrillating of the RV. A second electrode (130) perforates the apex (98) of the right ventricle (84) and is actively fixed into the apex (99) of the left ventricle (LV) (86). Electrode (130) is used for pacing, sensing and/or defibrillating of the LV. |
