摘要： Different types of cardiac arrhythmia are classified based on the morphology of the arrhythmic beats. Cardiac beats associated with an arrhythmic episode are compared to a plurality of representative beat morphologies, each representative beat morphology characterizing a type of arrhythmia. An arrhythmic episode may be classified as a particular type of arrhythmia if the morphology of the arrhythmic cardiac beats matches a representative beat morphology characterizing the particular type of arrhythmia. A particular type of arrhythmia may be associated with one or more therapies used to treat the arrhythmia. The therapy used to treat the arrhythmia may comprise a therapy identified as a previously successful therapy, for example.

摘要： A cardiac rhythm management device is configured to discriminate between ventricular and supraventricular tachycardias (referred to as SVT/VT discrimination) by utilizing a morphology criterion in which the morphology of electrogram waveforms during ventricular beats are analyzed to determine if the beats are normally conducted. After the delivery of a cardioversion/defibrillation shock, however, the intraventricular conduction system is left in a modified state which alters the subsequently generated electrogram signal. Use of the morphology criterion for SVT/VT discrimination is discontinued after delivery of such a shock and resumed after a predetermined minimum number of normally conducted ventricular beats has been detected.

摘要： A method and apparatus for implementing a signal morphology preservation smoothing scheme. The smoothing scheme includes generating an output signal representative of a filtered version of the input signal, wherein the output signal is generated by adaptively removing low amplitude, high frequency noise components while simultaneously preserving signal morphology of the input signal. The smoothing scheme includes comparison of a distance metric against a distance threshold to determine whether an initial smoothed version of the input signal would be oversmoothed or undersmoothed. Then the smoothing scheme appropriately increments, decrements, or maintains the initial level of smoothing to generate an optimal smoothed signal representative of the output signal.
