摘要： A fault-detection method, system, and device for a cryosurgical system that avoids a false-positive detection of a fault condition, such as fluid ingress within the system. The fault-detection mechanism may generally include a driver having an active mode and an inactive mode, the driver generating an output signal when the driver is in active mode, a detector, the detector capable of receiving the driver output signal, and a detector verification controller in communication with the driver and the detector, the detector verification controller changing the driver from the active mode to the inactive mode when the detector receives the driver output signal. The controller may determine a true fault condition if the controller determines there is a correlation between the signal received by the detector and the driver output signal. All other possible fault conditions may be ignored if the controller determines that the signals are not correlated.

摘要： Devices, systems, and techniques are described for selecting parameters for electrical stimulation therapy. For example, a 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.

摘要： A method of monitoring a patient for phrenic nerve collateral damage during a cardiac ablation procedure. The method includes measuring at least one from the group consisting of compound motor action potential (CMAP) and accelerometer signals in response to stimulating of the phrenic nerve. Real-time data is displayed on a display, the real-time data including the at least one from the group consisting of the measured CMAP and accelerometer signals. Long-term trend data is simultaneously displayed on the display, the long-term trend data being associated with the measured at least one from the group consisting of CMAP and accelerometer signals.

摘要： An implantable medical device comprising a signal generator configured to generate and deliver anti-tachyarrhythmia pacing (ATP) to a heart of a patient and processing circuitry. The processing circuitry is configured to detect an enable event, responsive to detecting the enable event, enable the delivery of ATP by the signal generator, detect a disable event indicating that another implantable medical device cannot be relied upon to deliver an anti-tachyarrhythmia shock, and responsive to detecting the disable event, disable delivery of ATP.

摘要： In situations in which an implantable medical device (IMD) (e.g., an extravascular ICD) is co-implanted with a leadless pacing device (LPD), it may be important that the IMD knows when the LPD is delivering pacing, such as anti-tachycardia pacing (ATP). Techniques are described herein for detecting, with the IMD 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 IMD includes a pace pulse detector that detects, based on the processing of sensed electrical signals, delivery of a pacing pulse from a second implantable medical device and blank, based on the detection of the pacing pulse, the sensed electrical signal to remove the pacing pulse from the sensed electrical signal.

摘要： 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.

摘要： 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.
