ABSTRACT:
A method for cardiac pacing and sensing is disclosed. A cardiac pacing lead is inserted into a heart chamber. The lead carries a plurality of separate electrodes positioned at the distal tip of the lead and transversely spaced from and electrically isolated from each other. A separate electrical conductor is provided for each electrode. A plurality of the electrodes are combined via electrical conductors to provide a relatively large electrode area for sensing cardiac activity. One of the electrodes is used for providing pacing pulses to the heart chamber. The pacing electrode has a relatively smaller surface area than the relatively large surface area used for sensing.
