Abstract
An active implantable medical device includes a detection electrode and a pulse generator. The pulse generator is configured to collect via the detection electrode at least two EGM signals, combine the EGM signals into two time components, and combine the components into a single 2D parametric characteristic representing the cardiac cycle. During a tachyarrhythmia episode, the device measures stores values of a cycle-to-cycle variation in an amplitude of the at least one of the EGM signals, distributes the amplitude variation values into a plurality of classes, each class corresponding to an amplitude interval, and analyzes a size of each of the plurality of classes to deliver at least one of an indicator of suspicion of an artifact of extracardiac origin or an indicator of a type of tachyarrhythmia selectively as a function of at least one predetermined criterion applied to the distribution of the amplitude variation values.
