Patients with ALBBB may have a favorable echocardiographic response to CRT and display similar survival rates to typical LBBB. This subgroup of IVCD should be considered for CRT. Atypical left bundle branch morphology defined as QS or rS in lead V1, broad R waves in lead I, and aVL but with QS or rS in V5-V6 is associated with favorable echocardiographic response to CRT and displays similar survival rates to typical LBBB patients.
