1. A subcutaneous implantable defibrillator (SID), the SID comprising:
- a housing configured to be implanted subcutaneously in a patient external to the heart of the patient;
one or more electrodes configured to be disposed external to the heart;
a shock module configured to at least partially deliver anti-tachyarrhythmia shock therapy to a patient via the one or more electrodes;
a communication module configured to at least one of transmit or receive communication messages with a second therapy device having a pacing therapy capability and configured to be implanted within a heart of the patient;
a sensing module configured to sense an electrical signal from the heart of the patient via the one or more electrodes; and
a controller circuit configured to;
detect a tachyarrhythmia within the sensed electrical signal;
determine, based on the detected tachyarrhythmia, to deliver anti-tachyarrhythmia shock therapy to the patient to treat the detected tachyarrhythmia; and
transmit, via the communication module, a communication message to the second therapy device requesting the second therapy device deliver anti-tachycardia pacing to the heart of the patient.

Abstract
This document discusses, among other things, a modular antitachyarrhythmia therapy system. In an example, a modular antitachyarrhythmia system includes at least two separate modules that coordinate delivery an antitachyarrhythmia therapy, such as defibrillation therapy. In another example, a modular antitachyarrhythmia therapy system includes a sensing module, an analysis module, and a therapy module.

10. A subcutaneous implantable cardioverter defibrillator (SICD), the SICD comprising:
-
a housing configured to be implanted in a patient external to a rib cage of the patient; one or more electrodes configured to be disposed external to the patient'"'"'s heart; a shock module configured to at least partially deliver anti-tachyarrhythmia shock therapy to a patient via the one or more electrodes; a communication module configured to at least one of transmit or receive communication messages between a leadless pacing device (LPD) configured to be implanted within a heart of the patient; a sensing module configured to sense an electrical signal from the heart of the patient via the one or more electrodes; and a processor configured to; detect a tachyarrhythmia within the sensed electrical signal; determine, based on the detected tachyarrhythmia, to deliver anti-tachyarrhythmia shock therapy to the patient to treat the detected tachyarrhythmia; and transmit, via the communication module and prior to delivering anti-tachyarrhythmia shock therapy, a communication message to the LPD requesting the LPD deliver anti-tachycardia pacing to the heart of the patient. - View Dependent Claims (11, 12, 13, 15, 16, 17, 18, 19, 20, 21, 22, 23)

14. A method of treating a patient comprising:
-
implanting a first module comprising a subcutaneous implantable defibrillator (SID) at a predetermined subcutaneous location outside of the heart of the patient; and implanting a second therapy device within the heart of the patient; wherein the SICD comprises; a housing configured to be implanted subcutaneously in a patient external to the heart of the patient; one or more electrodes configured to be disposed external to the heart; a shock module configured to at least partially deliver anti-tachyarrhythmia shock therapy to a patient via the one or more electrodes; a communication module configured to at least one of transmit or receive communication messages with a second therapy device having a pacing therapy capability and configured to be implanted within a heart of the patient; a sensing module configured to sense an electrical signal from the heart of the patient via the one or more electrodes; and a controller circuit configured to direct operations of the first module; and further wherein the controller circuit of the SID is configured to; detect a tachyarrhythmia within the electrical signal sensed by the sensing module; determine, based on the detected tachyarrhythmia, to deliver anti-tachyarrhythmia shock therapy to the patient to treat the detected tachyarrhythmia; and transmit, via the communication module, a communication message to the second therapy device requesting the second therapy device deliver anti-tachycardia pacing to the heart of the patient.
