Claim 21:
22. A method for controlling delivery of cardiac therapy by an implantable medical device system comprising a plurality of electrodes, the method comprising,
by processing circuitry of the medical device system:
determining, using sensing circuitry, a current heart position state of a patient is a first heart position state rather than a second heart position state, wherein determining the current heart position state of the patient is the first heart position state rather than the second heart position state comprises determining at least one of a respiratory phase, a respiratory rate, or a respiratory depth of the patient;
modifying, based at least in part on the determined at least one of the respiratory phase, the respiratory rate, or the respiratory depth of the patient, a vector comprising at least two of the plurality of electrodes based on the determined current heart position state being the first heart position state;
modifying, based at least in part on the determination of the current heart position state being the first heart position state, at least one anti-tachyarrhythmia shock therapy parameter value by increasing or decreasing an anti-tachyarrhythmia shock magnitude; and
controlling the medical device system to deliver anti-tachyarrhythmia shock therapy via the modified vector comprising the at least two of the plurality of electrodes and according to the modified at least one anti-tachyarrhythmia shock therapy parameter value associated with the first heart position state.
