A member asked:

Sir, can propranolol in therapeutic dose cause lbbb in a healthy heart?

A doctor has provided 1 answer
Dr. Ira Friedlander answered

Specializes in Cardiac Electrophysiology

In general beta: blockers like propranolol at appropriate doses will not have an effect on the conduction system. If LBBB developed on therapeutic doses it is more likely to represent disease of the conduction system.

Dr Hegab and another doctor agreed
