	'''Left bundle branch block''' ('''LBBB''') is a condition in which there's a delay or obstruction along the pathway that electrical impulses travel to make your heart beat. The delay or blockage occurs on the pathway that sends signals to the left side of your heart. [[Left bundle branch block]] is often associated with other heart conditions, such as [[heart disease]] or [[hypertension]].
