A method and apparatus are disclosed for treating a condition of a patient's heart includes placing a first electrode and/or a second electrode in a right ventricle of the heart. In one example, a reference electrode is placed within the patient and internal or external to the heart. A pacing signal is generated including a first signal component, a second signal component and a reference component with the first and second signal components having opposite polarity and with both of the first and second components having a potential relative to the reference component. The pacing signal and the placement of the electrodes are selected to alter a contraction of a left ventricle of the heart.

Ventricular pacing

A new pacemaker apparatus for treating the physiological electric conduction of the heart that includes a conduction abnormality in a ventricle. The pacemaker includes a pulse generator and a pacing electrode located in the heart, the pulse generator providing pacing signals to the pacing electrode. The pacemaker further includes a signal generation circuit that generates electrical signals from heart-related feedback signals that indicate that the pacing electrode is delivering the pacing signals in a region at or near the His bundle of the heart. The combination of the pulse generator and the signal generation circuit indicates that the pacing electrode is delivering the pacing signals in the region, at or near the His bundle of the heart, to electrically bypass the conduction abnormality of the heart in the ventricle.

Apparatus for treating the physiological electric conduction of the heart

Treating the physiological electric conduction of the heart includes methods that involve guiding an electrode to a location, near the His bundle of the heart, that is determined by pacing the heart and sensing signals in response thereto, and electrically bypassing a conduction abnormality of the heart by presenting extrinsic pacing signals to the location near the His bundle of the heart. The pacing electrode may then be fixed at the location, near the His bundle, to provide subsequent pacing of the heart such that the subsequent pacing exhibits electrical bypassing of the conduction abnormality.

Methods for treating the physiological electric conduction of the heart

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.

A pacing signal is generated including a first signal component, a second signal component and a reference component with the first and second signal components having opposite polarity and with both of the first and second components having a potential relative to the reference component. The first component is transmitted to the first electrode. The second component is transmitted to the second electrode. The reference electrode is connected to the reference component which may be an electrical ground. The pacing signal and the placement of the electrodes are selected to alter a contraction of a left ventricle of the heart.
