What are the types of bundle branch blocks?

There are two types of bundle branch blocks:

  • Right bundle branch block (RBBB): RBBB occurs when a disruption happens along the pathway that sends electrical signals to your right ventricle.
  • Left bundle branch block (LBBB): LBBB occurs when a disruption happens along the pathway that sends electrical signals to your left ventricle.

You can have a disruption in one bundle or in both your left bundle and your right bundle at the same time.
