1. A method for operating a cardiac rhythm management device, comprising:

  • sensing atrial depolarizations through an implanted atrial electrode;

    administering a sequential CRT pacing therapy in a sequential CRT pacing mode to a left and right ventricle of a heart of a patient via implanted ventricular electrodes in a sequential bi-ventricular fashion;

    switching from the sequential CRT pacing mode to a simultaneous CRT pacing mode;

    administering a simultaneous CRT pacing therapy in the simultaneous CRT pacing mode to the left and right ventricle in a simultaneous bi-ventricular fashion; and

    analyzing the sensed atrial depolarizations to detect the presence of an atrial arrhythmia.
