Abstract: In some examples, a method for controlling delivery of cardiac therapy and cardiac sensing by a medical device system including electrodes for delivering the cardiac therapy may include storing, in a memory of the medical device system, a respective value for each of a plurality of cardiac therapy and/or sensing parameters and, in association with each of a plurality of heart position states, a respective modification of at least one of the cardiac therapy and/or sensing parameters. Such a method also may include determining a current one of the plurality of heart position states of the patient, modifying the at least one cardiac therapy and/or sensing parameter value according to the modification associated with the current heart position state, and controlling the delivery of the cardiac therapy and/or cardiac sensing according to the modified at least one cardiac therapy and/or sensing parameter value.

Abstract: In some examples, medical device systems that deliver anti-tachyarrhythmia shock(s) (e.g., defibrillation shock(s)) to a heart of a patient in coordination with the respiration of the patient. In one example, a medical device system including therapy generation circuitry configured to generate a defibrillation shock. The medical device system also includes processing circuitry configured to identify a time at which a respiratory volume of a lung of a patient is at approximately end tidal volume or less; and control the therapy generation circuitry to deliver the defibrillation shock to a heart of the patient at the time that the respiratory volume of the lung of a patient is at the approximately end tidal volume or less.

Abstract: This disclosure describes implantable medical leads and medical device systems utilizing the leads. In some examples, an implantable medical lead comprises a first defibrillation electrode and a second defibrillation electrode, the first and second defibrillation electrodes configured to deliver anti-tachyarrhythmia shocks, and a pace electrode disposed between the first defibrillation electrode and the second defibrillation electrode, the pace electrode configured to deliver a pacing pulse that generates an electric field proximate to the pace electrode. The implantable medical lead further comprises a shield disposed between the first defibrillation electrode and the second defibrillation electrode and over a portion of an outer surface of the pace electrode, wherein the shield is configured to impede the electric field in a direction from the pace electrode away from a heart.

Abstract: Techniques are disclosed for automatically calibrating a reference orientation of an implantable medical device (IMD) within a patient. In one example, sensors of an IMD sense a plurality of orientation vectors of the IMD with respect to a gravitational field. Processing circuitry of the IMD processes the plurality of orientation vectors to identify an upright vector that corresponds to an upright posture of the patient. The processing circuitry classifies the plurality of orientation vectors with respect to the upright vector to define a sagittal plane of the patient and a transverse plane of the patient. The processing circuitry determines, based on the upright vector, the sagittal plane, and the transverse plane, a reference orientation of the IMD within the patient. As the orientation of the IMD within the patient changes over time, the processing circuitry may recalibrate its reference orientation and accurately detect a posture of the patient.
