| left bundle branch block |
The term bundle branch block refers to the QRS morphology seen when the left bundle branch fails to conduct from the His bundle to the ipsilateral ventricle. Complete left bundle branch block is characterized by negative forces (QS or rS) in V1 and positive forces (monophasic R wave with no Q wave) in V6. Incomplete left bundle branch block can manifest as left anterior hemiblock or left posterior hemiblock.
