Radiofrequency Catheter Ablation of Idiopathic Right Ventricular Outflow Tract Arrhythmias
Idiopathic ventricular arrhythmias (VA) consist of various subtypes of VA that occur in the absence of clinically apparent structural heart disease. Affected patients account for approximately 10% of all patients referred for evaluation of ventricular tachycardia (VT). Arrhythmias arising from the outflow tract (OT) are the most common subtype of idiopathic VA and more than 70-80% of idiopathic...
متن کاملClinical and electrophysiological spectrum of idiopathic ventricular outflow tract arrhythmias.
OBJECTIVES This study sought to compare and contrast the clinical and electrophysiological characteristics of outflow tract arrhythmias. BACKGROUND Idiopathic ventricular outflow tract arrhythmias manifest clinically in 3 forms: 1) paroxysmal sustained monomorphic ventricular tachycardia (SMVT), 2) repetitive nonsustained ventricular tachycardia (NSVT), or 3) premature ventricular contraction...
متن کاملDifferentiating origins of outflow tract ventricular arrhythmias: a comparison of three different electrocardiographic algorithms
Our objective is to evaluate the accuracy of three algorithms in differentiating the origins of outflow tract ventricular arrhythmias (OTVAs). This study involved 110 consecutive patients with OTVAs for whom a standard 12-lead surface electrocardiogram (ECG) showed typical left bundle branch block morphology with an inferior axis. All the ECG tracings were retrospectively analyzed using the fol...
متن کامل10-year follow-up after radiofrequency ablation of idiopathic ventricular arrhythmias from right ventricular outflow tract
BACKGROUND The aim of this study was to examine the effect of radiofrequency ablation (RFA) of ventricular arrhythmias from right ventricular outflow tract (RVOT) during long-term follow-up. METHODS A follow-up analysis was conducted using an in-house questionnaire, as well as a qualitative assessment of the patients' medical records. The study population of 34 patients had a previous diagnos...
متن کاملCharacteristics of diurnal ventricular premature complex variation in right ventricular outflow tract arrhythmias after catheter ablation
Diurnal variations in ventricular tachyarrhythmias (VAs) have been demonstrated in idiopathic arrhythmogenic heart disease. The electrophysiological characteristics of diurnal variations in idiopathic right ventricular outflow tract (RVOT) VA have not previously been elucidated. Sixty-two consecutive patients undergoing catheter ablation for idiopathic RVOT VA (mean age: 42.8 ± 12.3 years, 35 f...
