Abstract:
1. An implantable medical device for providing cardiac defibrillation and single-chamber pacing therapies, the implantable medical device comprising: an implantable lead assembly including a first electrode and a second electrode, the first electrode comprising a coil electrode configured to provide a defibrillation energy to a subject heart, and the second electrode configured to locally provide a pacing signal to a region at or near a His bundle of the subject heart; and a pulse generator circuit, wherein the pulse generator circuit is configured to provide, to the implantable lead assembly, non-defibrillating electrostimulation pulses including the pacing signal and including at least two pulses of opposite polarity and occurring sufficiently proximate one another in at least one of time or distance to elicit myocardium capture of the subject heart.
