DETECTION of ventricular tachyarrhythmia in currently available ICDs relies primarily on an evaluation of the sequence of ventricular event timing intervals obtained from a rate sense amplifier and comparator circuitry. (Chap. 14) The term “sensing” is reserved for the noting of a depolarization (ventricular event); “detection” is the processing of these sensed depolarizations and noting the presence of an arrhythmia. These timing intervals (also called R-R intervals) are classified by comparing them to a programmable parameter known as a rate zone limit (boundary). Depending upon an R-R interval’s relationship to the programmed boundaries, algorithmic detection criteria such as duration (specified in time or number of events) may be applied to the sequence of depolarizations.
