    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.

    Abstract: A method for adjusting a pacing rate in a dual-chamber, leadless pacemaker implanted in a heart may involve determining, with a leadless atrial pacemaker implanted in an atrium of the heart, that an intrinsic atrial contraction rate of the atrium is faster than a ventricular contraction rate, transmitting a first signal from the atrial pacemaker to a leadless ventricular pacemaker implanted in a ventricle of the heart to increase a ventricular pacing rate of the ventricular pacemaker, receiving the transmitted first signal with the ventricular pacemaker, and increasing the ventricular pacing rate, based on the received first signal.

    Abstract: A method and medical device for detecting signals that detects emitted light scattered by a volume of tissue delivered along a first pathway at a plurality of wavelengths to generate corresponding first detected light intensity output signals, detects emitted light scattered by the volume of tissue delivered along a second pathway different from the first pathway at a plurality of wavelengths to generate corresponding second detected light intensity output signals, determines whether a difference between the emitted light detected along the first pathway and the emitted light detected along the second pathway is greater than a predetermined threshold, and alters sensing by the device in response to the determining whether a difference is greater than the predetermined threshold.
