1. A method for multi-tier pacing comprising:
- delivering single site, left ventricular pacing;
sensing patient activity;
comparing the sensed patient activity to a patient activity threshold;
if the sensed patient activity exceeds the patient activity threshold, then delivering multi-site, left ventricular pacing for a predetermined period of time; and
after the predetermined period of time, delivering single site, left ventricular pacing.

Abstract
An exemplary method for multi-tier pacing includes delivering single site, left ventricular pacing, sensing patient activity; comparing the sensed patient activity to a patient activity threshold and, if the sensed patient activity exceeds the patient activity threshold, then delivering multi-site, left ventricular pacing for a predetermined period of time and, after the predetermined period of time, delivering single, site left ventricular pacing. In such a method, the period of time may be determined based on cardio-pulmonary demand. Other exemplary technologies are also disclosed.

11. A method for multi-tier pacing, the method comprising:
-
providing a first pacing tier that comprises left ventricular pacing only wherein the pacing paces the left ventricle at at least one left ventricular pacing site; providing a second pacing tier that comprises bi-ventricular pacing; providing a third pacing tier that comprises left ventricular pacing wherein the pacing paces the left ventricle at a greater number of left ventricular pacing sites than the first pacing tier; sensing patient activity; and selecting the first, second or third pacing tier for delivery of pacing therapy based at least in part on the sensed patient activity.

12. A method for multi-tier pacing, the method comprising:
-
providing a first pacing tier that comprises single-site ventricular pacing; providing a second pacing tier that comprises multi-site ventricular pacing; providing a decision tree to decide whether to select the first pacing tier or the second pacing tier based on cardio-pulmonary demand; and calling for delivery of pacing therapy according to the first pacing tier or the second pacing tier based on a decision of the decision tree. - View Dependent Claims (13, 14, 15, 16)
