Patent ID: 8712520

Claim:
An apparatus comprising: an implantable cardiac rhythm/function management device comprising: a cardiac contractility modulation (CCM) therapy circuit configured to deliver a CCM therapy including a non-stimulatory electrical energy during a refractory period of the heart; a tachyarrhythmia circuit, configured to perform a tachyarrhythmia function comprising: detecting a tachyarrhythmia using an intrinsic cardiac signal morphology analysis circuit configured to compare an intrinsic cardiac signal morphology to a CCM morphology template or a non-CCM morphology template; and delivering tachyarrhythmia therapy; and a controller circuit, coupled to the CCM therapy circuit and the tachyarrhythmia circuit, the controller circuit configured to obtain or provide information about the CCM therapy and information about the tachyarrhythmia therapy, the controller circuit configured to adjust at least one of the CCM therapy or the tachyarrhythmia therapy using the information obtained by the controller circuit including information about whether the other of the CCM therapy or the tachyarrhythmia therapy is being delivered or has been scheduled to be delivered, wherein the controller is configured to adjust a morphology analysis using information from the CCM therapy circuit about whether a CCM condition is present, the controller being configured to direct the intrinsic cardiac signal morphology analysis circuit to compare: an intrinsic cardiac signal morphology to the CCM morphology template if a CCM condition is present; or an intrinsic cardiac signal morphology to the non-CCM morphology template if a CCM condition is not present.
