    摘要: An implantable medical device includes a radio-frequency (RF) telemetry circuit connected to an energy source through a power connection module to obtain power when a user initiates an RF telemetry session. After the session is completed, the power connection module shuts off the at least one portion of the RF telemetry circuit. Power-on examples include a wireless telemetry activation signal received by a low power radio receiver in the implantable device, a physical motion detected by an activity sensor therein, an activation of an inductive telemetry circuit therein, a magnetic field detected by a magnetic field detector therein, and/or a telemetry activation signal detected by a sensing circuit included therein. Power-off examples include a wireless termination signal received by the implantable device, a delay timeout after the session, and/or a signal received by an inductive telemetry circuit in the implantable device.

    摘要: A personal watercraft has a saddle with a seating surface, first and second opposite sides, and front and back ends. A pair of footing surfaces proceed from proximate lower edges of first and second opposite sides. A front recess is defined in the front end and has upper and lower portions that extend further away from the saddle than a medial portion. A back recess is defined in the back end and has upper and lower portions that extend further away from the saddle than a medial portion. The front and back recesses are configured to secure an inflatable body that substantially surrounds the saddle with the footing surfaces at least partially exposed.

    摘要: Systems and methods of managing features or functions of an implantable cardiac device involve forming a baseline evoked response template prior to delivery of defibrillation therapy to a patient's heart, and acquiring a post-shock evoked response signal subsequent to defibrillation therapy delivery. The baseline evoked response template is compared to the post-shock evoked response signal. A determination is made whether to enable, disable or adjust a cardiac device feature based on the comparison. The cardiac device feature may be a therapy feature, a monitoring feature, or a diagnostic feature.

    摘要: An implantable cardiac rhythm management device is configured to remove pacing artifacts from recorded electrograms by a subtraction method. A template waveform representing a recorded pace without accompanying cardiac electrical activity is generated. Such a pacing pulse template is then aligned with the instant at which a pace is delivered and subtracted from the recorded electrogram in order to remove the pacing artifact.

    摘要: An apparatus and method for verifying capture by first and second pacing pulses in which an evoked response waveform recorded during a pacing event is compared with template waveforms representing capture by the first, second, and both pacing pulses. The evoked response is then classified as representing a type of capture represented by a template waveform if the evoked response waveform highly correlates with one template waveform and has correlation values with the other template waveforms within specified bounds.

    摘要: A CRM system enhances intracardiac electrogram-based arrhythmia detection using a wireless electrocardiogram (ECG), which is a signal sensed with implantable electrodes and approximating a surface ECG. In one embodiment, an intracardiac electrogram allows for detection of an arrhythmia, and the wireless ECG allows for classification of the detected arrhythmia by locating its origin. In another embodiment, the wireless ECG is sensed as a substitute signal for the intracardiac electrogram when the sensing of the intracardiac electrogram becomes unreliable. In another embodiment, a cardiac signal needed for a particular purpose is selected from one or more intracardiac electrograms and one or more wireless ECGs based on a desirable signal quality. In another embodiment, intracardiac electrogram-based arrhythmia detection and wireless ECG-based arrhythmia detection confirm with each other before indicating a detection of arrhythmia of a certain type.

    摘要: A method and system for the detection of electromagnetic interference is disclosed in which a telemetry coil or other magnetic sensor is used to detect a magnetic signal. If a magnetic signal is determined to be a non-telemetry signal and is time-correlated with the onset of an increase in heart rate, electromagnetic interference is assumed to be present.

    摘要: An apparatus and method for verifying capture by a pacing pulse in which a test depolarization waveform recorded during a pacing event is compared with a template waveform representing capture by the pacing pulse. Capture verification in this manner may be used in pacemakers having multiple pacing channels for the atrial and/or ventricles where the multiple paces can interfere with conventional sensing of evoked responses in order to verify capture.
