1. A method of identifying a tachyarrhythmia of a heart of a patient, the method comprising:
- sensing cardiac activity by a first implantable medical device;
sensing cardiac activity by a second implantable medical device, wherein the second implantable medical device is spaced from the first implantable medical device and communicatively coupled to the first implantable medical device via conducted communication through a communication pathway that includes the body of the patient;
communicating sensed cardiac activity by the first implantable medical device to the second implantable medical device, the communicated sensed cardiac activity including sensed cardiac activity other than a determination or provisional determination of a tachyarrhythmia; and
determining by the second implantable medical device if a tachyarrhythmia is occurring based, at least in part, on both the cardiac activity sensed by the second implantable medical device and the cardiac activity sensed by the first implantable medical device including at least some of the communicated sensed cardiac activity other than a determination or provisional determination of a tachyarrhythmia from the first implantable medical device.

Abstract
Systems and methods for coordinating detection and/or treatment of abnormal heart activity using multiple implanted devices within a patient. In one example, cardiac activity may be sensed by two or more medical device, including a leadless cardiac pacemaker. Cardiac activity sensed by one of the implanted devices may be communicated to another one of the implanted devices. Abnormal heart activity may then be determined based on the cardiac activity of both of the medical device.

11. A medical system for identifying a tachyarrhythmia in a heart of a patient, the medical system comprising:
-
a plurality of leadless cardiac pacemakers configured to detect cardiac activity at corresponding locations of the heart; and an Implantable Cardioverter Defibrillator (ICD) communicatively coupled to each of the plurality of leadless cardiac pacemakers via a communication pathway that includes the body of the patient, the ICD determining if a tachyarrhythmia is occurring based, at least in part, on the cardiac activity detected by two or more of the plurality of leadless cardiac pacemakers. - View Dependent Claims (12, 13, 14, 15, 16, 17)

18. A method of identifying a tachyarrhythmia of a heart of a patient, the method comprising:
-
sensing cardiac activity by a medical device; sensing cardiac activity by a first leadless cardiac pacemaker, wherein the first leadless cardiac pacemaker is communicatively coupled to the medical device via a communication pathway that includes the body of the patient; determining, by one or more of the medical device and the first leadless cardiac pacemaker, if a tachyarrhythmia is occurring based, at least in part, on the cardiac activity sensed by the medical device and/or the cardiac activity sensed by the first leadless cardiac pacemaker; and after determining a tachyarrhythmia is occurring, determining, by one or more of the medical device and the first leadless cardiac pacemaker, a type of the tachyarrhythmia based, at least in part, on both the cardiac activity sensed by the medical device and the cardiac activity sensed by the first leadless cardiac pacemaker. - View Dependent Claims (19, 20)
