A simple way to diagnose a left bundle branch in an ECG with a widened QRS complex (> ms) would be to look at lead V1. If the QRS complex is widened and downwardly deflected in lead V1, a left bundle branch block is present. The image below shows the typical findings of a left. If the QRS complex is widened and downwardly deflected in lead V1, a left bundle branch block is present. If the QRS complex is widened and upward deflected in lead V1, then a right bundle branch block is present. Below shows the typical findings of a left bundle branch block in.
