Fast pathway ablation in patients with common atrioventricular nodal reentrant tachycardia and prolonged PR interval during sinus rhythm.
AIMS This study aimed to clarify the safety and efficacy of selective fast pathway ablation in patients with atrioventricular nodal reentrant tachycardia and a prolonged PR interval during sinus rhythm. Such patients have been reported to have an increased incidence of complete atrioventricular block. METHODS AND RESULTS In this study, the earliest retrograde atrial activation during atrioven...
متن کاملRisk of development of delayed atrioventricular block after slow pathway modification in patients with atrioventricular nodal reentrant tachycardia and a pre-existing prolonged PR interval.
AIMS The objective of this prospective study was to assess risk factors for the development of atrioventricular block following slow pathway modification in patients with atrioventricular nodal reentrant tachycardia and a pre-existing prolonged PR interval. METHODS AND RESULTS Of 346 consecutive patients with atrioventricular nodal reentrant tachycardia undergoing slow pathway modification, 1...
متن کاملElectrophysiology Study for Complex Supraventricular Tachycardia in Congenital Heart Disease Patients With Single‐Ventricle Physiology
BACKGROUND Supraventricular tachycardia (SVT) is common in complex congenital heart disease (CCHD) patients with single-ventricle physiology and may cause hemodynamic deterioration. We reported the outcomes of catheter ablation for such complex SVT in these single-ventricle CCHD patients. METHODS AND RESULTS Patients with single-ventricle physiology (defined as CCHD patients) who received ele...
متن کاملCatheter-induced 3:1 second degree atrioventricular nodal block during atrioventricular nodal reentrant tachycardia.
Second-degree atrioventricular (AV) nodal block with 2:1 AV conduction during atrioventricular nodal reentrant tachycardia (AVNRT) has been previously described. We report a patient who developed AVNRT during which 3:1 intra-infra-Hisian block due to catheter manipulation was observed. This was followed by gradual, incremental recovery of AV conduction. AVNRT accounts for approximately 50% of c...
متن کاملComparison of late results of surgical or radiofrequency catheter modification of the atrioventricular node for atrioventricular nodal reentrant tachycardia.
AIMS Although arrhythmia surgery and radiofrequency catheter ablation to cure atrioventricular nodal reentrant tachycardia differ in technical concept, the late results of both methods, in terms of elimination of the arrhythmogenic substrate and procedure-related new and different arrhythmias, have never been compared. This constituted the purpose of this prospective follow-up study. METHODS ...
