Pacing and sensing vectors
First Claim
1. An implantable medical device (IMD) including a non--transitory processor-readable medium comprising instructions that, when performed by the processor cause the TIVI) to:
- receive information about a selection of a combination of ventricular electrodes for use in delivery of a cardiac pacing pulse, the selection including an indication of a cathode electrode and an anode electrode; and
control generation of a cardiac pacing pulse for delivery across t le combination of electrodes according to the selection; and
wherein the selectable combination includes an anode electrode and a cathode electrode, the anode electrode located along a first intravascularly-delivered lead within a great vein, the cathode electrode located along a separate second intravascularly-delivered lead.

Abstract
A method for allowing cardiac signals to be sensed and pacing pulse vectors to be delivered between two or more electrodes. In one embodiment, cardiac signals are sensed and pacing pulse vectors are delivered between at least one of a first left ventricular electrode and a second left ventricular electrode. Alternatively, cardiac signals are sensed and pacing pulse vectors are delivered between different combinations of the first and second left ventricular electrodes and a first supraventricular electrode. In addition, cardiac signals are sensed and pacing pulse vectors are delivered between different combinations of the first and second left ventricular electrode, the first supraventricular electrode and a conductive housing. In an additional embodiment, a first right ventricular electrode is used to sense cardiac signals and provide pacing pulses with different combinations of the first and second left ventricular electrodes, the first supraventricular electrode and the housing.
