Pacing crosstalk detection

A method performed by an implantable pacemaker, the pacemaker comprising:

• sensing a cardiac electrical signal received by a pair of electrodes coupled to the pacemaker,
• starting a pacing escape interval by a control module of the implantable pacemaker to control a time that a pacing pulse is delivered in a heart chamber of a patient;
• detecting the sensed cardiac electrical signal as a crosstalk event, the crosstalk event being an electrical pulse delivered to the patient by a different medical device than the implantable pacemaker, and
• withholding restarting the pacing escape interval in response to sensing the cardiac electrical signal based on detecting the sensed cardiac electrical signal as the crosstalk event.

A non-transitory, computer-readable storage medium comprising a set of instructions which, when executed by a control module of an implantable pacemaker, cause the pacemaker to:

• sense a cardiac electrical signal received by a pair of electrodes coupled to the pacemaker;
• start a pacing escape interval by a control module of the implantable pacemaker to control a time that a pacing pulse is delivered in a heart chamber of a patient;
• detect the sensed cardiac electrical signal as a crosstalk event, the crosstalk event being an electrical pulse delivered to the patient by a different medical device than the implantable pacemaker, and
• withhold restarting the pacing escape interval in response to sensing the cardiac electrical signal based on detecting the sensed cardiac electrical signal as the crosstalk event.
