DEVICES, SYSTEMS AND METHODS TO INCREASE COMPLIANCE WITH A PREDETERMINED VENTRICULAR ELECTRICAL ACTIVATION PATTERN
First Claim
1. For use with an implantable system including a first lead having at least one electrode implantable within a right ventricular (RV) chamber, and a second lead having at least two electrodes implantable within a left ventricular (LV) chamber, a method for increasing compliance with a predetermined preferred ventricular electrical activation pattern, the method comprising:
- (a) using a plurality of different sensing vectors to obtain a plurality of intracardiac electrograms (IEGMs) that collectively enable electrical activations to be detected in at least the RV chamber and at at least two separate regions of the LV chamber;
(b) determining an actual ventricular electrical activation pattern based on the plurality of IEGMs;
(c) determining whether the actual ventricular electrical activation pattern matches the predetermined preferred ventricular electrical activation pattern; and
(d) delivering pacing that includes multisite LV (MSLV) pacing to achieve the predetermined preferred ventricular electrical activation pattern, if the actual ventricular electrical activation pattern does not match the predetermined preferred ventricular electrical activation pattern.

Abstract
Described herein are implantable systems and devices, and methods for use therewith, that can be used to increase compliance with a predetermined preferred ventricular electrical activation pattern. Such implantable systems preferably includes a first lead having at least one electrode implantable in a right ventricular (RV) chamber, and a second lead having at least two electrodes implantable in a left ventricular (LV) chamber. A plurality of different sensing vectors are used to obtain a plurality of IEGMs that collectively enable electrical activations to be detected in at least the RV chamber and at at least two separate regions of the LV chamber. The IEGMs can be obtained while the patient'"'"'s LV chamber is not being paced, or during bi-ventricular (BiV) pacing that includes pacing at only a single site within the LV chamber. An actual ventricular electrical activation pattern is determined based on the plurality of IEGMs. Additionally, there is a determination of whether the actual ventricular electrical activation pattern matches the predetermined preferred ventricular electrical activation pattern. If the actual ventricular electrical activation pattern does not match the predetermined preferred ventricular electrical activation pattern, then multisite LV (MSLV) pacing is delivered to achieve the predetermined preferred ventricular electrical activation pattern.

11. An implantable system, comprising:
-
a first lead having at least one electrode implantable in a right ventricular (RV) chamber; a second lead having at least two electrodes implantable in a left ventricular (LV) chamber; one or more sensing circuits configured to sense cardiac electrical activity; one or more pulse generator configured to produce pacing pulses; and a sensing vector controller configured to selectively connect subsets of the electrodes to a said sensing circuit to thereby provide a plurality of sensing vectors that enable a plurality of different intracardiac electrograms (IEGMs) to be obtained that collectively enable electrical activations to be detected in at least the RV chamber and at at least two separate regions of the LV chamber; an electrical activation pattern monitor configured to determine an actual ventricular electrical activation pattern based on the plurality of IEGMs; and determine whether the actual ventricular electrical activation pattern matches a predetermined preferred ventricular electrical activation pattern; and a pacing controller configured to selectively connect subsets of the electrodes to a said pulse generator to deliver pacing that includes multisite LV (MSLV) pacing to achieve the predetermined preferred ventricular electrical activation pattern, if the electrical activation pattern monitor determines that the actual ventricular electrical activation pattern does not match the predetermined preferred ventricular electrical activation pattern. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
