title: Arrhythmias in the coronary-care unit. V. Physiologic bases of paroxysmal bradycardia-dependent bundle branch block.
abstract: Bradycardia-dependent bundle branch block can occur during acute cardiac ischemia or infarction. Basic cellular electrophysiology helps in understanding the mechanisms involved. A review of the previous four vignettes of this series will be helpful in studying this vignette.
