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.

Modification of cardiac sensing and therapy

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.

Cardiac device system

A device and method are described for transmitting tissue conductance communication (TCC) signals. A device may be is configured to establish a transmission window by transmitting a TCC test signal at multiple time points over a transmission test period to a receiving device and detect at least one response to the transmitted TCC test signals performed by the receiving device. The IMD is configured to establish the transmission window based on the at least one detected response so that the transmission window is correlated to a time of relative increased transimpedance between a transmitting electrode vector and receiving electrode vector during the transmission test period.
