    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: A method and system for monitoring respiratory function that includes an impedance sensor configured to sense a first thoracic impedance waveform for at least one breath of a patient, a memory configured to store a first threshold slope value, and a processor configured to determine an first breath slope value in response to the impedance waveform, compare the first breath slope value to a first threshold slope value, and determine an indication of respiratory function of the patient in response to the comparing.
