A system for use in implanting an implantable cardiac device includes an external device operable to emulate the operation of the implantable cardiac device in accordance with a set of modality and operating parameters. An external programmer includes a transmitter for transmitting the set of operating and modality parameters and the external device includes a receiver for receiving the set of operating parameters transmitted by the external programmer. A memory within the external programmer stores the transmitted set of operating parameters and retransmits the set of operating parameters to the implantable cardiac device after it is implanted. The external programmer and external device each include a telemetry antenna. The external programmer and external device are arranged for aligning the telemetry antennas when the external programmer and external device are being used together. The external programmer further includes a control panel arrangement which enables convenient control panel positioning by an implanting physician.

System and method for implanting an implantable cardiac device

A defibrillator system includes an implantable defibrillator and a non-implantable external receiver. The implantable defibrillator includes a first sense channel for generating a first electrogram and a second sense channel for generating a second electrogram. The defibrillator further includes a cardioverter for applying cardioverting electrical energy to the heart and a transmitter for transmitting the first and second electrograms. The non-implantable receiver includes a display for simultaneously displaying the first and second electrograms. The implantable defibrillator may further include an event detector having a threshold for detecting cardiac events in one of the electrograms and an event marker generator for generating an event marker for each detected cardiac event. The transmitter transmits the event detection markers and the display displays the event detection markers and the thresholds with the corresponding electrogram.

Implantable atrial defibrillator and system having multiple channel

A telemetry system and method of monitoring cardiac activity or providing therapy to the heart for an implantable cardiac device. The system includes a receiver and a transmitter in an external programmer and a receiver section and transmitter section in the cardiac device. The receiver section and the transmitter section of the cardiac device generally remain in a de-energized state. The receiver section is energized at spaced apart time intervals to detect an initiation signal transmitted by the external programmer. If the initiation signal is detected, the receiver section and the transmitter section of the cardiac device are fully activated. The external programmer includes a signal strength indicating means for providing an indication of received signal strength which the user can use to position the receiver and transmitter in the external programmer for optimum received signal strength. An antenna is disposed in the header of the implanted device to facilitate communication at high speed.

Telemetry system for an implantable cardiac device

A method and computerized system for ECG data review and analysis are provided. In preferred embodiments, a transformation is performed on beat data and the transformed data are categorized into beat 'bins.' The clinician/user may select sensitivity to vary the number of bins created by the system. Once beats are preliminarily assigned to bins by the system, the clinician/user may review beats by bin and reassigned beats as desired. In preferred embodiments, recategorization is accomplished by 'dragging' a beat to a new bin with the aid of a pointing device or 'mouse.' In preferred embodiments, a superimposition mode allows dynamic review of beat graphs with automatic detection, color coding, and optional pause at abnormal beats. Audio information is also preferably provided to aid the clinician/user in detecting abnormal beats. A P-wave marker capability is also provided to give a constant reference point during beat review in the superimposition mode. Preferred embodiments also provide the clinician/user immediate access to surrounding real-time data when reviewing individual beats.
