ABSTRACT:
A heart stimulation apparatus for intracardial stimulation of heart tissue has an electrode device with an electrode head provided at the distal end thereof, having at least a first conductive surface and a second conductive surface, a stimulation pulse generator and a switch for selectively connecting the conductive surface(s) to the stimulation pulse generator in any combination. In order to reduce the energy consumption, an autocapture unit is provided which automatically tests a number of possible combinations of conductive surfaces for stimulation and selects the combination providing the lowest stimulation threshold for connection to the pulse generator. A heart signal detector can also be provided to which the electrode surfaces are also connectable in any combination, with the autocapture unit selecting an optimal combination for sensing as well.
