A system for providing optimized cardiac chamber resynchronization therapy (CRT) to a patient, comprising: means for obtaining at least one of an inter-atrial delay value and an intra-atrial delay value for a subject; and means for utilizing the at least one of the inter-atrial delay value and the intra-atrial delay value to set an operative atrio-ventricular (A-V) delay that enhances the hemodynamic effects of the CRT delivery.
