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.

Dependent claims

A system for using with a first lead implanted at or near a first region of a left ventricle (LV) of a heart and a second lead implanted at or near a different second region of the heart, the system comprising:

an implantable medical device (IMD), including:
a controller circuit configured to:
program a first pacing vector including a first anode and a first cathode each selected from two or more electrodes on the first lead or one or more electrodes on the second lead, at least one of the first anode or the first cathode selected from the two or more electrodes on the first lead;
program a second pacing vector including a second anode and a second cathode each selected from the two or more electrodes on the first lead or the one or more electrodes on the second lead, at least one of the second anode and the second cathode selected from the two or more electrodes on the first lead, the second anode different from the first anode or the second cathode different from the first cathode;
and
generate a therapy schedule including an indication of temporal relationship between at least a first pacing sequence and a second pacing sequence;
and
a pacing output circuit coupled to the first and second leads and the controller circuit, the pacing output circuit configured to, in accordance with the therapy schedule, generate and deliver the first pacing sequence according to the first pacing vector, and generate and deliver the second pacing sequence according to the second pacing vector,

An implantable medical device (IMD) including a non-transitory processor-readable medium comprising instructions that, when performed by the processor, cause the IMD to:

program a first pacing vector by selecting a first anode and a first cathode from two or more electrodes, on a first lead, adapted to be positioned at or near a first region of a left ventricle (LV), or one or more electrodes, on a second lead, adapted to be positioned at or near a second region different from the first region, at least one of the first anode or the first cathode selected from the two or more electrodes on the first lead;
program a second pacing vector by selecting a second anode and a second cathode from the two or more electrodes on the first lead or the one or more electrodes on a second lead, at least one of the second anode and the second cathode selected from the two or more electrodes on the first lead, the second anode different from the first anode or the second cathode different from the first cathode;
generate a therapy schedule including an indication of temporal relationship between at least a first pacing sequence and a second pacing sequence;
and
in accordance with the therapy schedule, generate and deliver the first pacing sequence according to the first pacing vector, and generate and deliver the second pacing sequence according to the second pacing vector.
