SYSTEMS AND METHODS FOR DETECTING DEVICE DISLODGMENT

摘要

Systems, methods, and devices for detecting dislodgment of an implantable device are disclosed. In one example, a method for determining a dislodgement status may comprise collecting, by the implantable device operating in a first operating mode, a first number of accelerometer signal samples during a cardiac cycle of the heart and using the first number of accelerometer signal samples to determine a first patient parameter and collecting, by the implantable device operating in a second operating mode, a second number of accelerometer signal samples during a cardiac cycle of the heart and using the second number of accelerometer signal samples to determine a dislodgment status of the implantable device, wherein the first number is smaller than the second number. In some further embodiments, the method may further include providing a notification of the dislodgment status to a remote device that is remote from the implantable medical device.

1. A method for determining a dislodgement status of an implantable device at an implant site on the heart of a patient, the implantable device having an accelerometer for providing an accelerometer signal, the method comprising:
collecting, by the implantable device operating in a first operating mode, a first number of accelerometer signal samples during a cardiac cycle of the heart and using the first number of accelerometer signal samples to determine a first patient parameter; collecting, by the implantable device operating in a second operating mode, a second number of accelerometer signal samples during a cardiac cycle of the heart and using the second number of accelerometer signal samples to determine a dislodgment status of the implantable device, wherein the first number is smaller than the second number; and providing a notification of the dislodgment status to a remote device that is remote from the implantable medical device.
