Discrepant results of the total pacing prematurity in orthodromic reciprocating tachycardia with right bundle branch block

The total pacing prematurity (TPP) is useful for distinguishing orthodromic reciprocating tachycardia (ORT) from atrioventricular nodal re‐entrant tachycardia, but it may not be effective in patients with right bundle branch block (RBBB). We faced this challenge in an elderly woman, as RBBB and a pr...

Sumario:The total pacing prematurity (TPP) is useful for distinguishing orthodromic reciprocating tachycardia (ORT) from atrioventricular nodal re‐entrant tachycardia, but it may not be effective in patients with right bundle branch block (RBBB). We faced this challenge in an elderly woman, as RBBB and a prolonged transseptal conduction made it difficult to diagnose the tachycardia using the TPP. It is important to consider the presence or absence of RBBB when evaluating the results of the TPP.[Image: see text]
