1. A method comprising:
- guiding at least two electrodes comprising a first electrode and a second 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 electrostimulation pulses to the location near the His bundle of the heart, the electrostimulation pulses comprising at least partially concurrent opposite polarity signals, wherein the electrostimulation pulses comprise a first monopolar pulse delivered from the first electrode with respect to a reference and a second monopolar pulse delivered from the second electrode with respect to the reference.

Abstract
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.

18. A method for treating a conduction abnormality of a heart, the method comprising:
-
presenting electrostimulation pulses from a pulse generator to at least two electrodes comprising a first electrode and a second electrode located at a location near the His bundle of the heart, the electrostimulation pulses comprising at least partially concurrent opposite polarity signals, wherein the electrostimulation pulses comprise a first monopolar pulse delivered from a first electrode with respect to a reference and a second monopolar pulse delivered from a second electrode with respect to the reference; detecting that the conduction abnormality of the heart is bypassed; and fixing the first and second electrodes at the location to provide subsequent electrostimulation pulses to the heart, wherein the subsequent electrostimulation pulses exhibits electrical bypassing of the conduction abnormality. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 36, 37)
