    Abstract: An implantable medical device includes a memory storing criteria for transitioning between states of a cardiac cycle model, the states including a P-wave state. The device also includes sensing circuitry that senses a cardiac signal that varies as a function of a cardiac cycle of a patient, and also includes processing circuitry coupled to the sensing circuitry. The processing circuitry is configured to detect an R-wave in the sensed cardiac signal, to determine an elapsed time since the detection of the R-wave, to determine one or more morphological values of a post-R-wave segment of the cardiac signal to compare the elapsed time and the one or more morphological values to the stored criteria for transitioning between the plurality of states of the cardiac cycle model, and to detect a P-wave in the sensed cardiac signal in response to a transition to the P-wave state of the cardiac cycle model.

    Abstract: This disclosure is related to devices, systems, and techniques for performing patient parameter measurements. In some examples, a medical device system includes an optical sensor configured to measure ambient light and a tissue oxygen saturation parameter and processing circuitry configured to determine that a current measurement of the tissue oxygen saturation parameter is prompted and control the optical sensor to perform an ambient light measurement associated with the current measurement of the tissue oxygen saturation parameter. The processing circuitry is further configured to determine, based on the ambient light measurement, at least one of whether to control the optical sensor to perform the current measurement of the tissue oxygen saturation parameter, when to control the optical sensor to perform the current measurement of the tissue oxygen saturation parameter, or whether to include the current measurement of the tissue oxygen saturation parameter in a trend of the tissue oxygen saturation parameter.

    Abstract: Systems, devices, and techniques for establishing communication between two medical devices are described. In one example, an implantable medical device comprises communication circuitry, therapy delivery circuitry, and processing circuitry configured to initiate a communication window during which the implantable second medical device is capable of receiving the information related to a cardiac event detected by a first medical device, the communication window being one of a plurality of communication windows defined by a communication schedule that corresponds to a transmission schedule in which the first medical device is configured to transmit the information, control the communication circuitry to receive, from the first medical device, the information related to the cardiac event that is indicative of a timing of the cardiac event with respect to a timing of the communication window, schedule and control delivery of a therapy according to the information related to the cardiac event.
