Key result
Single atrial extrastimuli from remote sites during slow-fast AV junctional reentrant tachycardia resulted in unusual resetting patterns in two patients.

Do single atrial extrastimuli from remote sites produce unusual resetting patterns during slow-fast AV junctional reentrant tachycardia?
Single atrial extrastimuli from remote sites can produce unusual resetting patterns during slow-fast AVJRT, highlighting complex electrophysiological behaviors in reentrant circuits.
Tritto et al. (1996) conducted a case report in slow-fast AV junctional reentrant tachycardia (AVJRT) (n=2). Single atrial extrastimuli was evaluated on Resetting patterns (alteration in return cycle length duration). Single atrial extrastimuli from remote sites during slow-fast AV junctional reentrant tachycardia resulted in unusual resetting patterns in two patients.
