Abstract
Implantable medical devices (IMDs), and methods for use therewith, reduce how often an IMD accepts false messages. Such a method can include receiving a message and performing error detection and correction on the message. Such a method can also include determining a quality measure indicative of a quality of the message and/or a quality of a channel over which the message was received, and determining whether to reject the message based on the quality measure.
Claims20
For use by a leadless pacemaker (LP) configured to be implanted in a first chamber of a patient's heart and configured to selectively deliver pacing pulses to the first chamber of the patient's heart, a method for reducing how often the LP accepts false messages from a further LP that is configured to be implanted in a second chamber of the patient's heart, the method comprising:
- receiving a message from the further LP, the message indicative of when the further LP sensed in intrinsic depolarization of, or delivered a pacing pulse to, the second chamber of the patient's heart;
- performing error detection and correction on the message;
- determining, based on results of the error detection and correction, a quality measure indicative of at least one of a quality of the message or a quality of a channel over which the message was received;
- and
- determining whether to reject the message based on the quality measure;
- wherein the message, if accepted, is used by the LP to at least one of trigger a timer or trigger an event.
A leadless pacemaker (LP) configured to be implanted in a first chamber of a patient's heart, the LP comprising:
- at least one receiver configured to receive messages from a further LP configured to be implanted in a second chamber of the patient's heart, one or more of the messages indicative of when the further LP sensed in intrinsic depolarization of, or delivered a pacing pulse to, the second chamber of the patient's heart;
- at least one of a processor or controller configured to:
- perform error detection and correction on a message received by the at least one receiver;
- determine a quality measure indicative of at least one of a quality of the message or a quality of a channel over which the message was received;
- and
- determine whether to reject the message based on the quality measure;
- wherein the message, if accepted, is used by the LP to at least one of trigger a timer or trigger an event.

- at least one of a processor or controller configure to:
- perform error detection and correction on a message received by the at least one receiver;
- determine whether the message was received within a message window, if the message is not uncorrectable;
- accept the message, if the message is not uncorrectable and is received within the message window;
- reject the message, if the message is uncorrectable, or if the message is not received within the message window;
- wherein the message, if accepted, is used by the LP to at least one of trigger a timer or trigger an event.
