Torsades de Pointes associated with QT prolongation after catheter ablation of paroxysmal atrial fibrillation
نویسندگان
چکیده
A 79-year-old woman who underwent catheter ablation for paroxysmal atrial fibrillation presented with Torsades de Pointes (TdP). Aggravation of prolonged QT interval which is most likely due to neural modulation by catheter ablation, played major role in the initiation of TdP. The patient was successfully treated with isoproterenol during acute stage and discharged after stabilization without implantation of permanent pacemaker or implantable cardioverter defibrillator.

Recurrent torsades de pointes after catheter ablation of incessant ventricular bigeminy in combination with QT prolongation.
A 45-year-old woman, who had received a single-chamber implantable cardioverter defibrillator (ICD) due to ventricular fibrillation 5 years ago, was admitted for catheter ablation of incessant right ventricular outflow tract bigeminy. After successful ablation recurrent torsades de pointes associated with a prolonged corrected QT (QTc) interval were initiated by polymorphic premature ventricula...
متن کاملCardiac 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...
متن کاملCurrent Strategy of Anti- Arrhythmic Drug Therapy for Persistent Atrial Fibrillation
Persistent atrial fibrillation (AF) is quite difficult to convert to sinus rhythm by spontaneous or pharmacological means. Although electrical conversion or catheter ablation may be an alternative therapy choice, some patients do not find these invasive treatments acceptable. If aiming for pharmacological sinus conversion, amiodarone has been mainly chosen despite its limited efficacy. In contr...
متن کاملCiprofloxacin induced acquired long QT syndrome in a patient under class III antiarrhythmic therapy.
We report one case of cardiac arrest related to ciprofloxacin administration. One female patient (aged 70 years old) developed a marked QTc prolongation (QTc = 0.62 s) within 24 hours of ciprofloxacin administration, with documented torsades de pointes and recurrent syncope that required defibrillation. The patient was under amiodarone and sotalol therapy for atrial fibrillation, with no obviou...
متن کاملHigh risk of QT interval prolongation and torsades de pointes associated with intravenous quinidine used for treatment of resistant malaria or babesiosis.
Cardiac toxicity may be associated with drugs used for malaria. Torsades de pointes (TdP) is a well-known adverse effect of quinidine when used for atrial fibrillation. Intravenous quinidine doses for resistant malaria are 2 to 3 times higher than those used for arrhythmias. Among 6 patients receiving quinidine for malaria or babesiosis, 4 developed QT interval prolongation and 2 experienced Td...
