Abstract
An implantable medical interventional device is adapted to provide therapy to a patient in whom the device is implanted to treat cardiac dysrhythmias including tachyarrhythmia. The device performs a plurality of functions corresponding to different levels of therapy for treatment of sensed dysrhythmias, including an electric shock waveform of predetermined energy content for delivery to the patient's heart to terminate at least one type of tachyarrhythmia. In response to cessation of the tachyarrhythmia after delivery of the electric shock waveform, the device promptly thereafter applies post-shock pacing pulses to the heart for a period of time sufficient to allow the heart to recover from the shock and to resume substantially normal sinus rhythm. The device may be upgraded by programming to select among the various functions as necessary to provide designated therapy by suppressing some functions and activating others. The functions include, among others, simulating different conditions of interaction between activity of the heart and the therapies offered by the device, based on stored intrinsic heart beat signals over a respective time period with modified settings of parameters associated with the therapies. The results of the simulated different conditions of interaction can be displayed to show the effectiveness of treatment by the device if the dysrhythmia were actually encountered while the device is programmed with the respective time period and parameter settings.
