1. A method for delivering anti-tachycardia pacing therapy to a heart of a patient, the method comprising:
- in a first one of a plurality of implantable medical devices, determining to deliver anti-tachycardia pacing therapy to the heart of the patient;
communicating a message from the first one of the plurality of implantable medical devices to a second one of the plurality of implantable medical devices, the message instructing the second one of the plurality of implantable medical devices to deliver anti-tachycardia pacing therapy to the heart, the message including one or more anti-tachycardia pacing therapy parameters provided by the first one of a plurality of implantable medical devices; and
in response to receiving the message that includes the one or more anti-tachycardia pacing parameters and the instruction to deliver anti-tachycardia pacing therapy to the heart, the second one of the plurality of implantable medical devices delivering a first one of a plurality of electrical stimulation pulses to the heart of the patient after a predefined amount of time following a QRS wave that is detected by the second one of the plurality of implantable medical devices after receiving the message, wherein the plurality of electrical stimulation pulses are based on the one or more anti-tachycardia pacing parameters that were included in the message.

Abstract
Systems and methods for coordinating treatment of abnormal heart activity using multiple implanted devices within a patient. In one example, abnormal heart activity may be sensed by a medical device system. One of the devices of the system may determine to deliver anti-tachycardia pacing therapy to the heart of the patient, and may communicate an instruction to another of the devices of the medical device system to deliver anti-tachycardia pacing (ATP) therapy to the heart. The receiving medical device may then deliver ATP therapy to the heart of the patient.

11. An implantable medical device system for delivering anti-tachycardia pacing therapy to a heart of a patient, the system comprising:
-
a first implantable medical device; a second implantable medical device, wherein the first implantable medical device and the second implantable medical device are communicatively coupled; wherein at least one of the first implantable medical device and the second implantable medical device is configured to deliver anti-tachycardia pacing therapy to the heart of the patient; wherein the first implantable medical device is configured to determine to deliver anti-tachycardia pacing therapy to the heart of the patient; wherein the first implantable medical device is configured to communicate multiple messages to the second implantable medical device to deliver anti-tachycardia pacing therapy to the heart of the patient; and the second implantable medical device is configured to deliver one anti-tachycardia pacing pulse to the heart in response to receiving each of the multiple messages. - View Dependent Claims (12, 13)
