1. A computer implemented method for detecting arrhythmias in cardiac activity, comprising:
under control of one or more processors configured with specific executable instructions,
measuring conduction delays between an atria (A) sensing site at an A electrode and each of multiple distinct left ventricular (LV) sensing sites at corresponding multiple LV electrodes to obtain corresponding multiple intrinsic A/LV intervals;
measuring conduction delays between a right ventricular (RV) sensing site at an RV electrode and each of the multiple LV sensing sites at the corresponding multiple LV electrodes to obtain corresponding multiple intrinsic VV intervals;
calculating a first atrial ventricular (AV) delay based on at least one of the intrinsic A/LV intervals;
calculating a second AV delay based on at least one of the intrinsic VV intervals;
selecting between i) a biventricular (BiV) pacing mode and ii) an LV only pacing mode based on a relation between the first and second AV delays; and
delivering a pacing therapy, utilizing a selected one of the BiV pacing mode or LV only pacing mode, based on the selecting operation.
