DISPOSITIF MÉDICAL IMPLANTABLE ACTIF DE DÉFIBRILLATION, COMPRENANT DES MOYENS PERFECTIONNÉS DE DISCRIMINATION ENTRE BRUIT EXTERNE ET RUPTURE DE SONDE ET DE CARACTÉRISATION DES TACHYARYTHMIES
The present invention relates to a kind of equipment, which picks up two EGM signals in the respective channel separated, to provide two corresponding time components. By two time component combinations at the single 2D parameter attributes for indicating cardiac cycle. During tachyarrhythmia breaking-out, the equipment stores the coherent value of the Cycle by Cycle variation of the amplitude of one of (104) described EGM signals, it assigns it in multiple classifications (each classification corresponds to an amplitude section), and execute (120,126) to each classification sum statistical analysis, so as to based on be applied to amplitude variations the indicator of the indicator of pseudomorphism or tachyarrhythmia outside the doubtful heart is selectively exported at least one predetermined criterion of various types of other distribution.
