Arrhythmia detection and confirmation
First Claim
1. A method for detecting a cardiac arrhythmia of a patient'"'"'s heart, comprising:
- receiving, by a leadless cardiac pacemaker fixed in the patient'"'"'s heart, an indication from a remote device that a cardiac arrhythmia has been identified by the remote device;
monitoring, by the leadless cardiac pacemaker, a signal generated by a sensor that is located within the patients'"'"' heart;
utilizing the monitored signal to provide confirmation that the cardiac arrhythmia identified by the remote device is in fact occurring;
when the cardiac arrhythmia is confirmed, delivering a therapy to treat the cardiac arrhythmia; and
wherein the remote device identifies the cardiac arrhythmia without using the signal generated by the sensor.

Abstract
Systems, methods, and devices for detecting or confirming fibrillation are discussed. In one example, a method for detecting a cardiac arrhythmia of a patients'"'"' heart comprises receiving, by a leadless cardiac pacemaker fixed in the patients'"'"' heart, an indication from a remote device that a cardiac arrhythmia is detected, monitoring by the leadless cardiac pacemaker a signal generated by a sensor that is located within the patients'"'"' heart, and based at least in part on the monitored signal, confirming whether a cardiac arrhythmia is occurring or not. In some embodiments, the method may further comprise, if a cardiac arrhythmia is confirmed, delivering a therapy to treat the cardiac arrhythmia.

12. A method comprising:
-
sampling, by a leadless cardiac pacemaker, a signal generated by a sensor in accordance with a first set of sampling parameters; receiving, by the leadless cardiac pacemaker, an indication from a remote device that a cardiac arrhythmia is detected by the remote device; after receiving the indication of an occurrence of a cardiac arrhythmia detected by the remote device, sampling by the leadless cardiac pacemaker, the signal generated by the sensor in accordance with a second set of sampling parameters, wherein the second set of sampling parameters are different from the first set of sampling parameters; confirming, based on the signal sampled according to the second set of sampling parameters, whether a cardiac arrhythmia is occurring or not; and when a cardiac arrhythmia is confirmed based on the signal sampled by the leadless cardiac pacemaker, delivering a therapy to treat the cardiac arrhythmia. - View Dependent Claims (13, 14, 15, 16)

17. A leadless cardiac pacemaker (LCP) comprising:
-
a plurality of electrodes; an accelerometer; and a controller connected to the plurality of electrodes and the accelerometer, the controller configured to; receive an indication from another device that an arrhythmia is detected, and in response, confirm whether a cardiac arrhythmia is occurring or not based at least in part on a signal generated by the accelerometer; and transmit whether a cardiac arrhythmia is confirmed. - View Dependent Claims (18, 19, 20)
