Title (EN) PRESSURE AND IMPEDANCE BASED DISCRIMINATION OF HEMODYNAMIC STABILITY
(FR) DISCRIMINATION À BASE DE PRESSION ET D'IMPÉDANCE DE STABILITÉ HÉMODYNAMIQUE
Abstract: front page image
(EN) An implantable cardioverter defibrillator evaluates the hemodynamic stability of an arrhythmia to determine whether or not to defibrillate. The device obtains cardiac pressure and cardiac impedance data and evaluates a phase relationship between these parameters. Hemodynamically stable rhythms will result in an out of phase relationship.
(FR) L'invention porte sur un défibrillateur implantable qui évalue la stabilité hémodynamique d'une arythmie pour déterminer s’il faut ou non  défibriller. Le dispositif obtient des données de pression cardiaque et d'impédance cardiaque et évalue une relation de phase entre ces paramètres. Des rythmes stables de façon hémodynamique conduiront à une relation hors phase.
