Abstract

•Cardiac resynchronization therapy (CRT) with adaptive pacing algorithm (aCRT) showed greater response than the echo-guided CRT in moderately wide QRS patients.•QRS prolongation was not observed with aCRT in moderately wide QRS patients.•The effect of aCRT was similar between patients with and without left bundle branch block.
