Case in brief

A 52-year-old male presented with complex electrocardiographic findings, including alternating patterns of complete left and right bundle branch blocks, characterized by both wide and narrow QRS complexes, alongside paroxysmal third-degree atrioventricular block. The patient's condition highlights the intricate interplay of these conduction abnormalities.

Diagnostic / clinical pearl

Clinicians should be aware of the potential for multiple patterns of bundle branch block to coexist, as this can complicate the interpretation of electrocardiograms.
