Episodic bundle branch blocks are a phenomenon associated with many clinical conditions seen in the emergency department. Intermittent BBBs by definition show both normal conduction and BBB within a single electrocardiographic tracing, where a transient BBB is described as a conduction defect that which then returns to normal. The most common cause of both transient and episodic BBB is rate related however there are many causes.1 Acute LBBB should lead to suspicion of acute coronary syndrome until proven otherwise, however other many other precipitating causes can factor into the overall clinical picture.
