    Check out Lead 1 and you get your answer right away.

    LBBB you will see a deep rapid S wave in V1 and will almost always see a wide QRS in Lead 1.

    RBBB you will see a terminal R wave in lead aVR and terminal S waves in leads I, aVL, V5 and V6

    This is an excellent website with more information than you can take. Analysis and Interpretation of the Electrocardiogram

    Look in V1. If the QRS is wider than normal and theres a P wave and a T wave it's a bundle branch block. No find your J point. Back track to the first deflection before the Jo point. If the deflection is up, it's right sided. If its down, it's left sided.
