title: Pseudo A-V block. Part I.
abstract: An example of junctional premature beats with concealed conduction has been presented. The arrhythmia mimics Mobitz Type II second-degree A-V block. Awareness of this arrhythmia when added to the fact that Mobitz Type II block is rarely seen with IWMI will prevent an improper or hasty diagnosis. Cardiac arrhythmias should be interpreted and managed in context of the clinical setting.
