Abstract:
A method and apparatus for classifying and treating tachyarrhythmias. A cardiac stimulator includes an algorithm that uses dual chamber sensing to determine the type of tachyarrhythmia detected. If the tachyarrhythmia is of a type that responds well to ventricular therapy, such as a tachyarrhythmia originating in the ventricle rather than the atrium, the tachyarrhythmia is grouped into a treatable category. Accordingly, the cardiac stimulator applies therapy, or therapies, to the ventricle to remedy the ventricular tachyarrhythmia.
