摘要： An apparatus comprises a primary cardiac signal sensing circuit to sense a first cardiac signal, a secondary cardiac signal sensing to sense a second cardiac signal, and an arrhythmia detection circuit. The primary sensing circuit includes at least first and second implantable electrodes, and the secondary sensing circuit includes a third implantable electrode to deliver high-energy shock therapy. The arrhythmia detection circuit detects tachyarrhythmia using the primary sensing circuit, determines correspondence between events sensed with the primary sensing circuit and events sensed with the secondary sensing circuit, and deems whether a detected rhythm is indicative of noise or is indicative of an arrhythmia according to the determined correspondence.

摘要： A system and method for passively testing a cardiac pacemaker in which sensing signal amplitudes and lead impedance values are measured and stored while the pacemaker is functioning in its programmed mode. The amplitude and impedance data may be gotten and stored periodically at regular intervals to generate a historical record for diagnostic purposes. Sensing signal amplitudes may also be measured and stored from a sensing channel which is currently not programmed to be active as long as the pacemaker is physically configured to support the sensing channel. Such data can be useful in evaluating whether a switch in the pacemaker's operating mode is desirable.

摘要： An apparatus comprises an implantable cardiac signal sensing circuit and a controller circuit. The implantable cardiac signal sensing circuit provides a sensed depolarization signal from a ventricle and a sensed depolarization signal from an atrium. The controller circuit includes an onset detection circuit and a classification circuit. The onset detection circuit detects an onset episode that includes fast cardiac depolarizations and identifies a depolarization that initiates the onset episode. The classification circuit classifies the onset episode as supra-ventricular tachycardia (SVT) when the initiating onset episode is identified in the atrium and the number of atrial depolarizations is greater than or equal to the number of ventricular depolarizations during the onset episode, and as ventricular tachycardia (VT) when the initiating onset depolarization is identified in the ventricle and the number of ventricular depolarizations is greater than the number of atrial depolarizations during the onset episode.

摘要： An apparatus comprises an implantable cardiac signal sensing circuit and a controller circuit. The implantable cardiac signal sensing circuit provides a sensed depolarization signal from a ventricle and a sensed depolarization signal from an atrium. The controller circuit includes a one-to-one detector circuit and a tachyarrhythmia discrimination circuit. The one-to-one detector circuit measures cardiac depolarization intervals of the atrium and the ventricle and determines whether a relationship of atrial depolarizations to ventricular depolarizations is substantially one-to-one. The tachyarrhythmia discrimination circuit increments a counter when detecting a shortening or prolonging of a V-V interval that immediately precedes the same shortening or prolonging of an A-A interval, classifies the episode as VT according to the counter, and provides the classification of the tachyarrhythmia episode to a user or process.
