Abstract
Systems and methods are described herein for detecting efficiency of pacing using external cardiac signals. A representative electrical signal morphology of the cardiac signals may be determined based on the plurality of electrical signals, and an efficacy of left bundle branch (LBB) engagement determined based on the representative electrical signal morphology.
