Medical device with triggered blanking period
First Claim
1. An implantable cardiac rhythm system comprising:
- a first implantable medical device configured to monitor a patient'"'"'s heart rhythm and provide shock therapy to correct the patient'"'"'s heart rhythm, the first implantable medical device further configured to detect a first heart beat of the patient from a first location;
a second implantable medical device configured to sense the patient'"'"'s heart, the second implantable medical device configured to detect the first heart beat of the patient from a second location; and
wherein the second implantable medical device, upon detecting the first heart beat, communicates an indication of the detected first heart beat to the first implantable medical device, and in response, the first implantable medical device institutes a blanking period having a blanking period duration such that a T-wave of the detected first heart beat is blanked out by the first implantable medical device so as to not be interpreted as a subsequent second heart beat.

Abstract
An implantable cardiac rhythm system includes a first implantable medical device configured to detect a first heartbeat from a first location, and a second implantable medical device configured to detect the first heart beat of the patient from a second location. The second implantable medical device, upon detecting the first heart beat, may communicate an indication of the detected first heart beat to the first implantable medical device, and in response, the first implantable medical device may institute a blanking period having a blanking period duration such that a T-wave of the detected first heart beat is blanked out by the first implantable medical device so as to not be interpreted as a subsequent second heart beat. In some instances, the first implantable medical device is an SICD and the second implantable medical device is a LCP.

13. An implantable medical device, comprising:
-
one or more electrodes for detecting a heart beat of a patient; a receiver for receiving via conducted communication from another medical device an indication of a detected heart beat; and in response to receiving the indication of the detected heart beat, instituting a blanking period having a blanking period duration, wherein the implantable medical device is configured to not identify a subsequent heart beat of the patient via the one or more electrodes of the implantable medical device during the blanking period duration. - View Dependent Claims (14, 15, 16, 17, 18)

19. A method of using data from a leadless cardiac pacemaker to improve performance of a subcutaneous implantable cardioverter, the method comprising:
-
detecting a first heart beat via the leadless cardiac pacemaker; detecting the first heart beat via the subcutaneous implantable cardioverter; communicating an indication of the detected first heart beat detected by the leadless cardiac pacemaker to the subcutaneous implantable cardioverter; and initiating a blanking period by the subcutaneous implantable cardioverter such that a T-wave of the detected first heart beat is blanked out by the subcutaneous implantable cardioverter so as to not be interpreted as a subsequent second heart beat. - View Dependent Claims (20)
