    Abstract: An implantable pacemaker is configured to sense a cardiac electrical signal received by a pair of electrodes coupled to the pacemaker, start a pacing escape interval to control a time that a pacing pulse is delivered in a heart chamber, and detecting if the sensed cardiac electrical signal is a crosstalk event that is an electrical pulse delivered to the patient by a different device than the implantable pacemaker. The implantable pacemaker withholds 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.

    Abstract: A device includes a signal generator module, a processing module, and a housing. The signal generator module is configured to deliver pacing pulses to an atrium. The processing module is configured to detect a ventricular activation event and determine a length of an interval between the ventricular activation event and a previous atrial event that preceded the ventricular activation event. The processing module is further configured to schedule a time at which to deliver a pacing pulse to the atrium based on the length of the interval and control the signal generator module to deliver the pacing pulse at the scheduled time. The housing is configured for implantation within the atrium. The housing encloses the stimulation generator and the processing module.

    Abstract: A method for sensing far-field R-waves in a leadless, intracardiac pacemaker implanted in an atrium of a patient's heart may involve sensing an electrical signal generated by the heart with two electrodes and a first sensing channel and/or a second sensing channel of the pacemaker, comparing a first timing marker from the first sensing channel with a second timing marker from the second sensing channel, and either determining that the sensed signal is a P-wave, if the first and second timing markers indicate that the sensed signal was sensed by the first and second sensing channels within a predetermined threshold of time from one another, or determining that the sensed signal is a far-field R-wave, if the sensed signal is sensed by the second sensing channel and not sensed by the first sensing channel.

    Abstract: The control module of a first pacemaker included in an implantable medical device system including the first pacemaker and a second pacemaker is configured to set a pacing escape interval in response to a far field pacing pulse sensed by the first pacemaker. The far field pacing pulse is a pacing pulse delivered by the second pacemaker. The pacing escape interval is allowed to continue without restarting the in response to a far field intrinsic event sensed by the first pacemaker during the pacing escape interval. The first pacemaker delivers a cardiac pacing pulse to the heart upon expiration of the pacing escape interval.

    Abstract: Techniques and systems for monitoring cardiac arrhythmias and delivering electrical stimulation therapy using a subcutaneous implantable cardioverter defibrillator (SICD) and a leadless pacing device (LPD) are described. For example, the SICD may detect a tachyarrhythmia within a first electrical signal from a heart and determine, based on the tachyarrhythmia, to deliver anti-tachyarrhythmia shock therapy to the patient to treat the detected arrhythmia. The LPD may receive communication from the SICD requesting the LPD deliver anti-tachycardia pacing to the heart and determine, based on a second electrical signal from the heart sensed by the LPD, whether to deliver anti-tachycardia pacing (ATP) to the heart. In this manner, the SICD and LPD may communicate to coordinate ATP and/or cardioversion/defibrillation therapy. In another example, the LPD may be configured to deliver post-shock pacing after detecting delivery of anti-tachyarrhythmia shock therapy.
