Abstract
This case report describes the electrocardiographic features of concealed junctional premature beats. When the junctional premature beats occurred in a bigeminal fashion, pseudo 2:1 AV block occurred. The presence of 2:1 AV block was related to the prematurity (H1-H2) of the junctional extrasystoles, in which coupling intervals less than 425 msec were concealed and those greater than 425 msec were manifest. This report is unusual in that persistent long runs of pseudo 2:1 AV conduction were established. In addition, the extrasystolic beats demonstrated exit block and the interectopic sinus beats (n) followed the formula 2n-1.
