Pacing systems for treating functional ventricular conduction abnormalities of intrinsic origin

摘要

Therapeutic implantable cardiac pacing systems incorporating electrocardiographic acquisition and QRS discrimination circuitry, for the purpose of ventricular pacing during wide QRS complexes of intrinsic origin, in order to narrow the QRS complex. Resultant narrowing of the QRS complex increases coronary artery flow and electrode position is employed to improve ventricular motion in the treatment of functional ventricular abnormalities caused by wide QRS complexes.
