Abstract:
An electrode arrangement comprising:an insulating case having a distal end and a plurality of electrically conductive surface regions spaced from one another in a line at the distal end; at least one electric line disposed within the insulating case, said at least one electric line enabling connection of the plurality of electrically conductive surface regions to a cardioelectric device, said plurality of electrically conductive surface regions performing at least one of outputting electrical signals to a heart and receiving electrical signals from a heart; first and second switching means, arranged at the distal end of the insulating case, for electrically connecting respective electrically conductive surface regions to a respective one of the at least one electric line where the resultant connections to the cardioelectric device can be made or broken by the first and second switching means at the respective electrically surface regions conductive of the insulating case; and control means arranged in the insulating case and connected to the respective one of the at least one electric line and to each respective electrically conductive surface region in order to receive control signals from the respective one of the at least one electric line and a respective electrically conductive surface region, said control means being electrically connected to said first and second switching means where the received control signals cause at least one of the first and second switching means to operate between a state of breaking the connection between the respective one of the at least one electric line and a respective electrically conductive surface region and a state of making the connection between the respective one of the at least one electric line and the respective electrically conductive surface region.
