    • A novel electrode apparatus and method for use with an automatic implantable cardioverter/defibrillator. The electrode apparatus includes a catheter electrode intravenously positioned within the heart of a patient wherein one electrode, defined by the catheter, is within the right ventricle and a second electrode, defined by the catheter, spaced from the first electrode, is within the superior vena cava. A third electrode, in the form of a flexible, substantially planar patch, is subcutaneously positioned outside the thoracic cavity proximate to the apex of the left ventricle. The third electrode is electrically connected with the second electrode of the catheter. The electrode arrangement can be implanted without opening of the thoracic cavity by intravenously placing the catheter electrode within the heart of a patient and subcutaneously implanting the patch electrode between the skin and the thoracic cavity. The automatic implantable cardioverter/defibrillator senses life-threatening arrhythmic conditions of the heart and issues at least one cardioverting or defibrillating pulse that is applied between the electrode positioned within the right ventricle and the electrode pair comprising the electrodes positioned within the superior vena cava and subcutaneously adjacent the apex of the left ventricle.

    • The invention relates to an arrhythmia detection system and method for defibrillating the heart of a patient experiencing abnormal cardiac rhythm, wherein the abnormal cardiac rhythm (comprising one of fibrillation, high rate tachycardia, and low rate tachycardia) is first detected, the heart rate is sensed so as to distinguish between fibrillation and high rate tachycardia, on the one hand, and low rate tachycardia, on the other hand, and automatic defibrillation of the heart of the patient is implemented when one of fibrillation and high rate tachycardia is determined. In one embodiment, base and apical electrodes are connected to a probability density function (PDF) circuit and a rate circuit. When both abnormal cardiac rhythm and excessively high heart rate are detected, defibrillation of the heart of the patient is implemented. In a second embodiment, a sensing button is also connected to the heart, and a switch is interposed between the electrodes and sensing button, on the one hand, and the interface, on the other hand. During monitoring of cardiac rhythm by the PDF circuit, the switch automatically connects the electrodes to the PDF circuit, while, during sensing of the heart rate, the switch connects the sensing button to the heart rate circuit. Upon detection of the need for defibrillation, the switch automatically connects the defibrillation pulse generator to the electrodes. Further features include a timed reset capability.

    • An implantable heart stimulator and related method calls for the determination of a given heart condition from among a plurality of conditions, the selection of at least one mode of operation for treating the determined condition, and the execution of the mode of operation selected, so as to treat the determined condition. In one embodiment of the invention, wherein a plurality of modes of operation for treating the various conditions are provided, the implantable heart stimulator includes processors, each processor being designed to efficiently execute a respective group of modes of operation. A further embodiment of the present invention calls for the implantable heart stimulator to be implemented by at least one programmable microprocessor. A still further embodiment calls for the provision of a data input/output channel, by means of which data can be provided to and retrieved from the implantable heart stimulator. Operations carried out by the implantable heart stimulator includes cardiac pacing, cardioversion, and automatic defibrillation. In a further embodiment of the implantable heart stimulator and related method, sensing circuitry is provided to determine the presence or absence of an R-wave of the heart, the absence of which causes a pacing operation to be implemented, further sensing circuitry being provided to determine the presence or absence of a forced R-wave of the heart, the absence of a forced R-wave causing ventricular defibrillation to be implemented.
