Patent ID: 8812105

Claim:
A method for treating an asynchronous condition of a heart of a patient, the method comprising: generating an electrostimulation profile that includes pulse waveforms for delivery via respective electrodes, the pulse waveforms including opposing polarities that are at least partially overlapping in time; and delivering the electrostimulation profile via the respective electrodes, the electrodes located in a right ventricle of the heart, at or near the septum of the heart and distal from an apex of the right ventricle; wherein the delivering the electrostimulation profile includes capturing the myocardium so as to improve synchronization of the right and left ventricles as compared to delivering pacing at the apex of the right ventricle; and wherein the generating the electrostimulation profile includes: in a first stage of a switching circuit, selecting one of a bi-ventricular switch configuration and a single-ventricle switch configuration to provide the pulse waveforms to a second stage of the switching circuit; in the second stage of the switching circuit, selecting an initial pulse polarity for providing the pulse waveforms to the respective electrodes; and recurrently alternating the pulse polarity using the second stage of the switching circuit.
