Defibrillator/Cardioverter/Pacemakers, Implantable, Resynchronization
Definition : Defibrillator/cardioverter/pacemakers that can also deliver simultaneous biventricular stimulations to synchronize ventricular contractions. Typically, the device (a dedicated pulse generator) is combined with a set of leads that includes two standard leads placed in both the right atrium and right ventricle and a third unipolar-electrode lead that is usually placed in a coronary vein (i.e., transvenously) that overlies the left ventricle. These devices add the capability of coordination (i.e., synchronization) of the left and right ventricles to obtain better pumping action. They are used for resynchronization therapy in patients with advanced heart failures (e.g., dilated cardiomyopathy) and/or serious heart-rhythm problems (e.g., ventricular dysynchrony).
