    摘要: A cardiac rhythm management (CRM) system includes an implantable cardioverter defibrillator (ICD) and an external system. The ICD includes a plurality of functional modules performing tachyarrhythmia classification and therapy control functions using atrial tachyarrhythmia rate thresholds that are set to a unified value. In one embodiment, the CRM system allows a user to activate and deactivate each of the functional modules and program the unified value using the external system.

    摘要: A cardiac rhythm management (CRM) system includes an implantable cardioverter defibrillator (ICD) and an external system. The ICD detects a tachyarrhythmia episode and classifies the detected tachyarrhythmia episode using none, one, or more of detection enhancements selected according to a selection command including a classification mode. The detection enhancements are each an algorithm for detecting and analyzing one or more indications of a type of the detected tachyarrhythmia episode. The external system allows a user to select the classification mode from a plurality of available classification modes each using none, one, or more of the detection enhancements.

    摘要: Systems and methods are described for classifying a cardiac rhythm. A cardiac rhythm is classified using a classification process that includes a plurality of cardiac rhythm discriminators. Each rhythm discriminator provides an independent classification of the cardiac rhythm. The classification process is modified if the modification is likely to produce enhanced classification results. The rhythm is reclassified using the modified classification process.

    摘要: Methods, systems and computer program products for combining atrial defibrillation treatment techniques include techniques for reducing the discomfort associated with defibrillation and/or reducing the defibrillation threshold. Techniques include timing the defibrillation shock to reduce discomfort based on a sensed signal, giving the shock relatively early during atrial fibrillation, therapeutic drugs, administering more than one shock in succession, pacing the heart before, after, or during the defibrillation shock or shocks, and placing the shock electrodes in locations that may reduce discomfort.

    摘要: An implantable vagal stimulation device with high-energy efficiency and novel data sensing is provided for use in a wide variety of applications where neural stimulation is required, including human heart rate control. The stimulation device uses low-impedance circuitry and digital waveforms to minimize energy losses, thereby requiring a relatively small battery. Front-loaded, passive filtering is employed to reduce electromagnetic noise sensitivity, leaving a clear physiological signal without degradations. This physiological signal is processed by a derivative zero transition detector (DZD), which is immune to variations in input signal dynamic range unlike traditional methods. Information that the DZD receives can be then interpreted and used along with an algorithm to execute appropriate vagal nerve stimulation.

    摘要: A method for operating a cardiac pacemaker in which the mode of operation of the pacemaker is altered in response to detecting an episode of atrial tachycardia. In accordance with the invention, the pacemaker's pacing mode is altered in a manner that attempts to maintain hemodynamic stability during the atrial tachycardia. Such a mode switch is particularly applicable to pacemaker patients suffering from some degree of congestive heart failure.
