    Abstract: An intracardiac pacemaker system is configured to produce physiological atrial event signals by a sensing circuit of a ventricular intracardiac pacemaker and select a first atrial event input as the physiological atrial event signals. The ventricular intracardiac pacemaker detects atrial events from the selected first atrial event input, determines if input switching criteria are met, and switches from the first atrial event input to a second atrial event input in response to the input switching criteria being met. The second atrial event input includes broadcast atrial event signals produced by a second implantable medical device and received by the ventricular intracardiac pacemaker.

    Abstract: Sensing circuitry of an implantable medical device (IMD) system may sense a cardiac signal that varies according to a cardiac cycle of a patient. Processing circuitry of the IMD system may determine a series of consecutive cardiac cycle length metric values based on the sensed cardiac signal, identify a plurality of pairs of the cardiac cycle length metrics, each of the pairs of cardiac cycle length metrics separated by an integer ‘n’ of the cardiac cycle length metrics, and construct a distribution of the pairs of cardiac cycle length metrics based on values of the cardiac cycle length metrics for each of the pairs. The processing circuitry may detect a sleep apnea episode of the patient based on one or more characteristics of the constructed distribution, and control communication circuitry of the IMD system to transmit an indication of the detected sleep apnea episode to the external computing device.

    Abstract: An implantable medical device has a housing having a proximal end, a distal end and an outer sidewall extending from the proximal end to the distal end. A fixation sheath includes a housing sheath portion extending along the outer sidewall of the housing, and a fixation member portion extending from the housing sheath portion. The housing sheath portion is advanceable from a first position along the outer sidewall of the housing in which the fixation member portion is retracted toward the proximal end of the housing to a second position along the outer sidewall of the housing in which the fixation member portion is deployed to extend away from the housing distal end for anchoring the implantable medical device at an implant site.
