Case report: intermittent, positive pressure ventilation-dependent right bundle branch block.
A 73-year-old man with severe chronic obstructive pulmonary disease and cor pulmonale developed an intermittent right bundle branch block (RBBB) during mechanical ventilation. The appearance and disappearance of his RBBB was temporally associated with each positive pressure breath. Intermittent RBBB is a previously undescribed complication of positive pressure ventilation.
