1. A method of using an implantable device comprising:
- acquiring right atrial activity data and left atrial activity data for intrinsic atrial activations and paced atrial activations, the data sufficient to determine intrinsic atrial activation times and paced atrial activation times;
providing a model for paced atrial activation times as a function of intrinsic atrial activation times;
fitting the model to the data;
using the model to predict a paced atrial activation time based on a subsequently determined intrinsic atrial activation time; and
using the predicted paced atrial activation time to provide pacing to an atria.

Abstract
An exemplary device includes control logic to determine a paced atrial activation time using a predictive model and an intrinsic atrial activation time and to determine an atrioventricular delay based at least in part on the paced atrial activation time. Such a device may be an implantable device configured to deliver cardiac therapy that uses atrial pacing and ventricular pacing. Such a device may be a programmer configured to program an implantable device configured to deliver cardiac therapy that uses atrial pacing and ventricular pacing. Various other exemplary technologies are also disclosed.
