    摘要： The invention provides systems to prevent the delivery of anti-tachycardia pacing (ATP) following a defibrillation threshold (DFT) induction at implant. An algorithm that classifies episodes as induced or spontaneous is implemented, thereby enabling the ATP during charging feature to be operable only when spontaneous episodes are detected while temporarily suspending the ATP feature during the delivery of defibrillation shock after induction has been confirmed. Further, a user interface enables users to interact with an implantable medical device (IMD), particularly for setting a defibrillation threshold (DFT) or a 50 Hz burst from a single programmer screen. The user interface includes various functionalities to promote quick user access to parameters that govern diagnosis, therapy and other features of the IMD. A single screen enables the user to complete automatic and/or manual DFT inductions or a 50 Hz burst from a programmer interface while acquiring associated documentation from the same interface.

    摘要： An implantable medical device (IMD) communication system and associated method for controlling the telemetry link status between an IMD and associated programmer during a telemetry session are provided. The system includes control circuitry for detecting conditions during predetermined time intervals for determining if a telemetry session is active or inactive. If a telemetry session is determined to be inactive for a specified interval of time, the telemetry link may be terminated or converted to a low-output, stand-by mode. Patient or device identity verification may be required prior to allowing programmer-IMD communication. A patient alert signal may be generated in response to programmer-IMD communication occurring after a predetermined time of telemetry session inactivity.

    摘要： Determining termination of an identified tachyarrhythmia episode may involve analysis of a relative decrease in tachyarrhythmia rate, a normalization of electrogram morphology criteria, or both. An implanted medical device may obtain a tachyarrhythmia rate and a morphology of a cardiac waveform. The device may compare the tachyarrhythmia rate to a threshold tachyarrhythmia rate and the morphology to a template morphology, and classify the heart beat as indicating termination of the tachyarrhythmia episode when the tachyarrhythmia rate is less than the threshold tachyarrhythmia rate, the morphology categorizes as normal, or both. For arrhythmias with no therapy delivered, observation of arrhythmia behavior at the point of termination may lead to improved classification. In addition, observation of a relative decrease in tachyarrhythmia rate immediately after therapy application can lead to application of slower but more specific criteria for redetection. Also, delivery of cardioversion shocks can be aborted upon tachyarrhythmia termination.

    摘要： Methods for improving detection of arrhythmias by adaptively increasing arrhythmia detection intervals. One method includes increasing the V2V, the overall cardiac cycle length, thereby decreasing the pacing rate in the presence of ventricular safety paces (VSPs). Another method includes shortening the trigger interval following the atrial pace event, during which time the pacemaker will detect V-sense events, while leaving the A2V VSP interval unchanged, at the end of which any required VSP will be generated. In yet another method, the interval from A-pace to V-pace, the PAV interval, is shortened, while leaving the overall V2V cycle interval unchanged. This increases the ventricular to artial V2A interval, increasing the detection window for arthythmias. The PAV interval can be shortened in response to a recent history of VSP events.

    摘要： A cyclic redundancy code (CRC) and optionally a syndrome value calculation of one or more implantable medical device (IMD) data block is conducted by block mover/reader hardware of the IMD when the data block(s) are moved and/or read. In the block read operation, each data byte or word in the block mover data register is read in a first clock cycle. In the block move operation, each data byte is read in the first clock cycle in this way and then moved to a destination register in a second clock cycle. The data CRC and optionally the syndrome value accumulate in the CRC and syndrome registers as all data bytes of the data block(s) are read in the first clock cycle. When the last data byte or word of the data block(s) is sequentially read (and moved in the block move operation), the accumulated data CRC and syndrome value are either stored as the associated data CRC and optional syndrome value or are used for comparison with a previously stored data CRC and optional syndrome value associated with the data block(s) in the comparison operation to determine if the data block(s) is corrupted.
