    What is left bundle branch block on a 12 lead ECG?
    Left bundle branch Block on a 12 lead ECG. Another example of Left bundle branch Block on a 12 lead ECG. In a LBBB, the last depolarization wave is in the left ventricle. This wave is directed away from V1. On the ECG, V1 will show a negative complex. In left bundle branch block (LBBB) the conduction in the left bundle is slow.

    What is a left bundle branch block in a precordial ECG?
    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 upwardly deflected in lead V1, a right bundle branch block is present. The image below shows the typical findings of a left bundle branch block in the precordial ECG leads.

    What is a negative complex in a left bundle branch block (LBBB)?
    On the ECG, V1 will show a negative complex. In left bundle branch block (LBBB) the conduction in the left bundle is slow. This results in delayed depolarization of the left ventricle, especially the left lateral wall. The electrical activity in the left lateral wall is unopposed by the usual right ventricular electrical activity.

    What is the QRS duration of left bundle branch block (LBBB)?
    A QRS duration of 120 ms (0.12 s) or more is required to diagnose a complete left bundle branch block. In addition to prolonged QRS duration, LBBB is characterized by deep and broad S-waves in leads V1 and V2 and broad, frequently nothed, R-wave in V5 and V6. Secondary ST-T changes occur invariably in the presence of LBBB.
