Methods for ventricular pacing
First Claim
1. A method comprising:
- determining an atrial to ventricular activation time for a right ventricle;
determining an atrial to ventricular activation time for a left ventricle; and
determining a pacing sequence that paces the right ventricle prior to activation of the left ventricle if the time for the right ventricle exceeds the time for the left ventricle or that paces the left ventricle prior to activation of the right ventricle if the time for the left ventricle exceeds the time for the right ventricle, wherein, in the pacing sequence, pacing of the prior, paced ventricle occurs at a time based at least in part on a difference between the time for the right ventricle and the time for the left ventricle.

Abstract
An exemplary method includes determining an atrial to ventricular activation time for a right ventricle; determining an atrial to ventricular activation time for a left ventricle; and determining a pacing sequence that paces the right ventricle prior to activation of the left ventricle if the time for the right ventricle exceeds the time for the left ventricle or that paces the left ventricle prior to activation of the right ventricle if the time for the left ventricle exceeds the time for the right ventricle, wherein, in the pacing sequence, pacing of the prior, paced ventricle occurs at a time based at least in part on a difference between the time for the right ventricle and the time for the left ventricle and an atrio-ventricular delay limit. Various other exemplary methods, devices and/or systems are also disclosed.
