Bradycardia dependent QT prolongation and ventricular fibrillation following catheter ablation of the atrioventricular junction with radiofrequency energy.

چکیده
Recurrent ventricular fibrillation was observed in a 67-year-old woman following catheter ablation of the AV junction using radiofrequency energy. This serious complication has been reported following direct current energy ablation of the AV junction, but not after using radiofrequency energy. This life-threatening arrhythmia seemed pause and bradycardia dependent. It was followed by QTc prolongation of the QRS escape rhythm 1 day after the procedure. Ventricular arrhythmias were suppressed by rapid ventricular pacing.

Cardiac Arrest Caused by Torsades de Pointes Tachycardia after Successful Atrial Flutter Radiofrequency Catheter Ablation
A 66-year-old woman underwent successful radiofrequency catheter ablation for long-lasting, drug refractory fast atrial flutter. Two days later she had a cardiac arrest due to torsades de pointes (TdP) tachycardia attributed to relative sinus bradycardia and QT interval prolongation. After successful resuscitation further episodes of TdP occurred, which were treated with temporary pacing. Becau...

The era of catheter ablation for the treatment of arrhythmias began in 1981, when Dr. Melvin Scheinman performed the first atrioventricular junction ablation using direct-current shocks in a patient with drug-refractory atrial fibrillation and an uncontrolled ventricular rate.1 Because of the barotrauma associated with intracardiac high-energy shocks, direct-current catheter ablation played onl...

INTRODUCTION Transcutaneous RF catheter ablation of the atrioventricular junction (AVJ) in pts with ventricular pacemaker (VVIR) implantated is an accepted treatment for drug-intolerant or drug refractory atrial fibrillation. The ventricular arrhythmias and sudden cardiac death may be associated with increased of QT dispersion (QTD), mainly in pts with reduced LV function (low ejection fraction...

BACKGROUND The Catheter Ablation Registry was the first international, multicenter, prospective study of the safety and efficacy of catheter ablation. METHODS AND RESULTS From August 1987 through March 1990, the study comprised 136 patients in whom only DC energy was used in attempted production of third-degree atrioventricular block to treat uncontrollable supraventricular tachycardias.
