Atrial fibrillation with intermittent right axis deviation in the presence of complete left bundle branch block.
Left bundle branch block is usually associated with normal or left axis deviation. Rarely the ecg shows an LBBB with changing QRS morphology and changing axis deviation. We describe a case of atrial fibrillation with intermittent right axis deviation in the presence of complete left bundle branch block in an 84-year-old Italian woman in the Cardiology Unit.
