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 a defibrillation therapy. In another example, a modular antitachyarrhythmia therapy system includes a sensing module, an analysis module, and a therapy module.

2. An implantable cardiac rhythm management system comprising:
-
a first module configured for subcutaneous implantation and having a controller and communications circuitry; and a second module configured for implantation in the heart of a patient, comprising a housing having first and second electrodes thereon and including communications circuitry for communicating with the first module and which is configured for attachment to cardiac tissue, the second module being entirely separate from the first module; wherein the first module is configured to identify a tachyarrhythmia and direct the second module to deliver antitachyarrhythmia therapy; wherein the first module is further configured to also deliver antitachyarrhythmia therapy as needed; and wherein the communications circuitry of each of the first and second modules is configured to use the body of the patient as a conductive medium for communication. - View Dependent Claims (4)

10. An implantable cardiac rhythm management system comprising:
-
a first module adapted for subcutaneous implantation and having a controller and sensing and communications circuitry; a second module adapted for atrial placement and including communications circuitry configured to send and receive signals with the first module by using the patient'"'"'s body as a conductive medium; a third module adapted for ventricular placement and including communications circuitry configured to send and receive signals with the first module by using the patient'"'"'s body as a conductive medium; wherein the system is configured for delivery of electrical cardiac therapy in which the first module controls the delivery of therapeutic energy by issuing commands after receiving sensing information from at least one of the second or third modules. - View Dependent Claims (11, 12, 13, 14, 15, 17, 18, 19, 20, 21)
