Therapeutic implantable cardiac pacing systems incorporating improved electrocardiographic acquisition systems for the purpose of ventricular pacing during wide ORS complexes of intrinsic origin, in order to narrow the QRS complex in patients where QRS narrowing is achievable and improving ventricular function in all patients with wide QRS complexes including those where ORS shortening does not result. These pacing systems are employed to increase coronary artery flow and electrode position is employed to improve ventricular motion in the treatment of functional ventricular abnormalities caused by wide ORS complexes.

Apparatus and methods for improving the ventricular activation sequence of the heart by pacing at an advantageous selected ventricular location to achieve shortening of the QRS complex or pacing at multiple advantageous selected ventricular locations, either simulataneously or with a programmed delay or delays between firings, to achieve shortening of the QRS complex in combination with producing a desirable and efficient ventricular motion. During a cardiac cycle initiated by intrinsic cardiac activity, stimulating impulses may be directed to advantageous selected locations of the ventricles by employing intrinsic cardiac signals to trigger the stimulating impulses, either simultaneously or with a programmed delay or delays between the sensed event or events and firing event or events, to provide improved mechanical and electrical ventricular function.

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.
