Recurrences of symptoms after AV node re-entrant tachycardia ablation: A clinical arrhythmia risk score to assess putative underlying cause

Junctional ectopic rhythm after AVNRT ablation: An underrecognized complication

“…We did not notice any IST on the Holters or ECGs available for our six JER patients. It is unclear whether some of the previous reports with IST or atrial tachycardia in symptomatic patients post‐AVNRT ablation might have included some JER …”

“…However, cryoablation comes at the cost of more arrhythmia recurrences and longer procedure times. Persistent palpitations after AVNRT ablation may reflect unsuccessful AVNRT ablation or the occurrence of new arrhythmias including inappropriate sinus tachycardia (IST), atrial fibrillation, or atrial flutter . Persistent palpitations might also reflect another very rarely described potential complication following AVNRT ablation: the occurrence of junctional ectopic rhythm (JER), including junctional ectopic tachycardia (JET) when rates exceed 100 beats/min.…”

“…Persistent palpitations after AVNRT ablation may reflect unsuccessful AVNRT ablation or the occurrence of new arrhythmias including inappropriate sinus tachycardia (IST), atrial fibrillation, or atrial flutter. 3,4 Persistent palpitations might also reflect another very rarely described potential complication following AVNRT ablation: the occurrence of junctional ectopic rhythm (JER), including junctional ectopic tachycardia (JET) when rates exceed 100 beats/min. This is a separate entity from the commonly induced junctional rhythm occurring during RF ablation which serves as a sign of success for slow pathway elimination, or which transiently occurs with the use of isoproterenol during the electrophysiology (EP) study for AVNRT induction.…”

AV nodal reentrant tachycardia or AV reentrant tachycardia using a concealed bypass tract-related adverse events

“…All antiarrhythmic drugs were discontinued at least five half-lives prior to the study. Details of the protocol have been previously described [8][9][10].…”

Look and you shall find: Perils along the road after slow pathway ablation for AV nodal reentry tachycardia

“…Brembilla‐Perrot et al. noted recurrence of arrhythmia symptoms in up to 16% of patients successfully ablated for AVNRT followed over an average period of 2.2 years . Invasive and noninvasive studies revealed sinus tachycardia (4.7%), recurrence of AVNRT (5.2%), and other atrial arrhythmias (6.1%) responsible for recurrent palpitations in a large cohort of 835 adult patients successively ablated for AVNRT.…”
