Abstract:
1. An implantable medical device comprising: an electric signal processor configured to process an electric signal and to detect, based on said electric signal, an intrinsic or induced atrial electric activity of a heart of a subject; a delay measurer configured to measure, based on said electric signal, an intrinsic atrioventricular delay between said detected intrinsic or induced atrial electric activity and any following intrinsic ventricular electric activity of said heart; a sensor arrangement that measures N parameters representative of N different physiological characteristics of said subject, where N≧2; a sub-space processor configured to identify, based on said measured N parameters, a sub-space of multiple sub-spaces comprised in a N-dimensional parameter space; and a delay assigner configured to assign an expected intrinsic atrioventricular delay to said identified sub-space based on said measured intrinsic atrioventricular delay, wherein said N-dimensional parameter space with assigned expected intrinsic atrioventricular delays constitutes decision support information for use in a selective pacing of said heart, wherein said delay assigner is configured to i) determine a time-weighted average of said measured intrinsic atrioventricular delay and at least one previously measured intrinsic atrioventricular delay assigned to said identified sub-space, and ii) assign said time-weighted average to said identified sub-space.
