    Abstract: Devices, systems, and techniques are described for selecting parameters for electrical stimulation therapy. For example, device may include processing circuitry configured to determine a first window of time to sense a physiological signal, determine, based on the first window of time, a second window of time for delivering electrical stimulations, and determine, based on a duration of the second window of time, a number of stimulation pulses deliverable during the second window of time at one or more pulse frequencies. The processing circuitry may then output, based on the number of stimulation pulses deliverable during the second window of time, at least one selectable stimulation parameter that at least partially defines the electrical stimulation, wherein the second window of time is adjacent to the first window of time.

    Abstract: In situations in which an implantable medical device (e.g., a subcutaneous ICD) is co-implanted with a leadless pacing device (LPD), it may be important that the subcutaneous ICD knows when the LPD is delivering pacing, such as anti-tachycardia pacing (ATP). Techniques are described herein for detecting, with the ICD and based on the sensed electrical signal, pacing pulses and adjusting operation to account for the detected pulses, e.g., blanking the sensed electrical signal or modifying a tachyarrhythmia detection algorithm. In one example, the ICD includes a first pace pulse detector configured to obtain a sensed electrical signal and analyze the sensed electrical signal to detect a first type of pulses having a first set of characteristics and a second pace pulse detector configured to obtain the sensed electrical signal and analyze the sensed electrical signal to detect a second type of pulses having a second set of characteristics.

    Abstract: A method and system for determining a target location for a medical device having complex geometry relative to an anatomical feature, and for navigating and positioning the medical device at the target location. The system may include a medical device including a treatment element having a centroid, one or more navigation electrodes, and a longitudinal axis and a navigation system in communication with the one or more navigation electrodes, the navigation system including a processing unit. The processing unit may be programmed to define a plane that approximates a surface of the anatomical feature, define a centroid of the anatomical feature, define a vector that is normal to the plane and extends away from the centroid of the anatomical feature, and determine a target location for the treatment element of the medical device based on the vector to assist the user in placing the device for treatment.

    Abstract: In some examples, an implantable medical device determines that another medical device delivered an anti-tachyarrhythmia shock, and delivers post-shock pacing in response to the determination. The implantable medical device may be configured to both detect the delivery of the shock in a sensed electrical signal and, if delivery of the shock is not detected, determine that the shock was delivered based on detection of asystole of the heart. The asystole may be detected based on the sensed electrical signal. In some examples, an implantable medical device is configured to revert from a post-shock pacing mode to a baseline pacing mode by iteratively testing a plurality of decreasing values of pacing pulse magnitude until loss of capture is detected. The implantable medical device may update a baseline value of the pacing pulse magnitude for the baseline mode based on the detection of loss of capture.

    Abstract: A method and system for automatic location of a target treatment structure, such as a pulmonary vein ostium, from an anatomical image. The method includes calculating a most likely path of blood flow through a pulmonary vein based on a cross-sectional area minimization technique and calculating pulmonary vein geometry as a function of length. For example, a pulmonary vein ostium may be located by analyzing a change in pulmonary vein dimensional size or other anatomical factors, such as absolute size. The method may also include determining tissue thickness at the pulmonary vein ostium or other treatment size for treatment dose optimization. The method may be an algorithm performed by a processing unit of a navigation system or other component of a medical system.
