Apparatus for treating the physiological electric conduction of the heart
First Claim
1. An apparatus, comprising:
- an electrostimulation pulse generator, configured to provide an electrostimulation signal to a first electrode disposed in a subject heart; and
a His capture verification signal generator, configured to generate an electrical His capture verification signal based on information about whether the electrostimulation signal from the first electrode evokes a response that bypasses a ventricular conduction abnormality of the subject heart;
wherein the pulse generator provides the electrostimulation signal to the first electrode in the subject heart as an electrostimulation signal comprising at least partially concurrent opposite polarity signals.

Abstract
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.
