System and method for detecting tamponade
First Claim
1. A method for detecting a tamponade condition of a patient'"'"'s heart after attachment of a leadless cardiac pacemaker to the patient'"'"'s heart, the leadless cardiac pacemaker having an accelerometer that produces an accelerometer signal, the method comprising:
- monitoring the accelerometer signal of the leadless cardiac pacemaker;
determining if a tamponade condition of the patient'"'"'s heart is indicated based at least in part on the monitored accelerometer signal, including;
identifying a characteristic of the accelerometer signal;
determining if the identified characteristic diminishes over time; and
determining that the tamponade condition is indicated if the identified characteristics of the accelerometer signal diminishes over time; and
in response to determining that the tamponade condition is indicated, providing a notification of the tamponade condition for use by a physician to take corrective action.

Abstract
Systems, methods, and devices for determining occurrences of a tamponade condition are disclosed. One exemplary method includes monitoring an accelerometer signal of a leadless cardiac pacemaker attached to a heart wall, determining if a tamponade condition of the patient'"'"'s heart is indicated based at least in part on the monitored accelerometer signal, and in response to determining that the tamponade condition is indicated, providing a notification of the tamponade condition for use by a physician to take corrective action.

11. A leadless cardiac pacemaker for use in pacing a patient'"'"'s heart, comprising:
-
a plurality of electrodes; an accelerometer for providing an accelerometer signal; a controller operatively coupled to the plurality of electrodes and the accelerometer, the controller configured to; monitor the accelerometer signal of the accelerometer over time; determine if a tamponade condition of the patient'"'"'s heart is indicated based at least in part on the monitored accelerometer signal, including; identifying a characteristic of the accelerometer signal; determining if the identified characteristic diminishes over time; and determining that the tamponade condition is indicated if the identified characteristic of the accelerometer signal diminishes over time; and in response to determining that the tamponade condition is indicated, communicate a notification of the tamponade condition for use by a physician to take corrective action. - View Dependent Claims (12, 13, 14)

15. A leadless cardiac pacemaker, comprising:
-
a plurality of electrodes; an accelerometer for providing an accelerometer signal; a controller operatively coupled to the plurality of electrodes and the accelerometer, the controller configured to; monitor an indication of a range of physical motion of a patient'"'"'s heart over time using the accelerometer signal; determine if the indication of the range of physical motion of the patient'"'"'s heart reduces over time by at least a predefined amount; and if it is determined that the indication of the range of physical motion of the patient'"'"'s heart has reduced over time by at least the predefined amount, communicate a notification of a possible tamponade condition for reception by a remote device that is remote from the leadless cardiac pacemaker. - View Dependent Claims (16, 17, 18)
