Patent ID: 8233979

Claim:
A method for use when pacing and sensing in a chamber of a patient's heart using a lead that includes a first group of at least two electrically isolated electrodes within 5 mm of one another and using a further electrode that is at least 10 mm from the first group, comprising: (a) when pacing, using as a pacing cathode at least one of the electrodes of the first group; (b) when pacing, using as a pacing anode at least one of the electrodes of the first group that is not used as the pacing cathode, together with the further electrode that is at least 10 mm from the first group also being used as the pacing anode; (c) when sensing, using as the sensing cathode the same electrode(s) that is/are used as the pacing cathode when pacing at step (a); and (d) when sensing, using as the sensing anode the same electrodes that are used as the pacing anode when pacing at step (b).
