Fast pathway ablation in a patient with iterative atrioventricular nodal reentrant tachycardia and prolonged PR interval

A safe approach to radiofrequency catheter ablation is still unclear and not well defined in patients with AV nodal reentrant tachycardia and prolonged PR interval. In our study, a patient with iterative AV nodal reentrant tachycardia and prolonged PR interval underwent fast pathway radiofrequency c...

Description
Summary:A safe approach to radiofrequency catheter ablation is still unclear and not well defined in patients with AV nodal reentrant tachycardia and prolonged PR interval. In our study, a patient with iterative AV nodal reentrant tachycardia and prolonged PR interval underwent fast pathway radiofrequency catheter ablation. By mapping Koch's triangle, the earliest retrograde atrial activation area was localized. Radiofrequency energy was delivered here with the interruption of tachycardia with no complications.
