| 摘要 |
The invention concerns an implantable heart stimulating device (10) with a control circuit (14) with first (16, 18) and second (17, 19) means for sensing and pacing. The first means (16, 18) can be connected to a first electrode member (31, 32) suited to be positioned in or at a first ventricle (1V) of the heart. The second means (17, 19) can be connected to a second electrode member (41, 42) suited to be positioned in or at a second ventricle (2V) of the heart. The control circuit (14) is arranged to be able detect whether signals sensed by said second means (17, 19) are likely to be far field signals. The control circuit (14) is arranged to perform this detection by at least determining whether, during a predetermined time length, more signals are sensed by said second means (17, 19) than by said first means (16, 18). The invention also concerns a system including such a device (10) as well as a use of such a system. <IMAGE>
