Patent attributes
The present invention provides for a method and apparatus providing pacing to improve the hemodynamics of the heart for patients with AV nodal block, right/left bundle branch block, and heart failure. A lead body having at least one conductor with an insulative sleeve is introduced into the right atrium of a heart. A partially masked helical electrode connected to the conductor is then secured preferably into the atrial aspect of the atrioventricular septum. The electrical conductor is then rotated such that an unmasked portion of the electrode is moved to a depth within the heart tissue substantially near the heart's intrinsic conduction system. This method and apparatus allow pacing in a natural manner via low power stimulation of the heart's intrinsic conduction system.
