Pacemaker which reestablishes or keeps the physiological electric conduction of the heart and a method of application
First Claim
1. A method comprising:
- delivering electrostimulation pulses to a first septal location in the right ventricle of the heart near a His bundle to stimulate the conduction system of the heart near the His bundle, the electrostimulation pulses comprising at least partially overlapping opposite polarity signals;
determining if a resulting contraction of the ventricles elicited via the delivery of the electrostimulation pulses to the first location exhibits one or more of a normal depolarization-repolarization pattern and a narrow QRS;
delivering the electrostimulation pulses to a second septal location in response to a determination that the resulting contraction of the ventricles elicited via the delivery of the electrostimulation pulses to the first location did not exhibit one or more of a normal depolarization-repolarization pattern and a narrow QRS width; and
securing an electrode at the second septal location in response to a determination that the contraction elicited in response to delivering electrostimulation pulses to the second septal location exhibits one or more of a normal depolarization-repolarization pattern and a narrow QRS width.

Abstract
A pacemaker is disclosed which reestablishes or keeps the physiological electric conduction of the heart and a method of application. The pacemaker is a pulse generator, it has a ventricular output including at least two superimposed monopolar pulsewaves of reversed polarity between each other, with programmable configuration, with respect to a neutral which can be the pacemaker'"'"'s metallic box or a third electrode in the case of a tripolar catheter. The catheter can have a deflectable sheath, with an electrode on its distal tip. The invention consists of a new pacemaker, and a method of application in the right ventricular septum, being able to use in order to facilitate the implantation and to avoid the connection and the disconnection, a sheath to check a proper place and then screw the catheter in said place. This method and the pacemaker are the responsible of reestablishing or preserving the physiological electrical conduction of the heart due to the creation of an alternative electric circuit and to the creation of a virtual electrode.
