1. A method for use by an implantable cardiac rhythm management device equipped to selectively deliver multi-site left ventricular (MSLV) pacing within a patient, the method comprising:

  • delivering non-simultaneous MSLV pacing to the heart of the patient within a tracking mode;

    assessing the atrial rate of the patient; and

    comparing an atrial rate against an atrial tachycardia assessment rate threshold (ATAR) and, if the atrial rate exceeds the ATAR threshold, switching from non-simultaneous MSLV pacing to one of substantially simultaneous MSLV pacing and single-site LV pacing to facilitate recognition of organized atrial arrhythmias (OATs).
