The purpose of this study was to report the results and complications radiofrequency catheter ablation accessory atrioventricular (AV) connections by using an abbreviated approach aimed at minimizing duration procedure.Two hundred fifty consecutive patients with Wolff-Parkinson-White syndrome or paroxysmal supraventricular tachycardia involving a concealed AV connection underwent use current. In 179 250 patients, performed time initial electrophysiology test. Two thirty-five had one 15 two...

Background: Optimal timing for catheter ablation of ventricular tachycardia is an important unresolved issue. There are no randomized trials evaluating the benefit after first implantable cardioverter defibrillator (ICD) shock. Methods: We conducted a 2-phase, prospective, multicenter, clinical trial. Patients with ischemic or nonischemic dilated cardiomyopathy and primary secondary prevention indication ICD were enrolled in initial observational phase until appropriate shock (phase A)....

Ten consecutive patients with recurrent episodes of symptomatic, idiopathic, sustained monomorphic ventricular tachycardia (VT) originating in the right ventricle underwent an attempt at catheter ablation tachycardia. There were seven women and three men, a mean age 39 +/- 14 years (+/- SD). None had any evidence structural heart disease. The VT left bundle branch block configuration inferior axis each patient, cycle length was 313 75 msec. Based on methods induction response to verapamil,...

Catheter ablation of accessory atrioventricular (AV) connections has been demonstrated to be effective in more than 85% patients. One the risks this procedure is radiation exposure during fluoroscopic imaging necessary guide catheter manipulation. The objective present study was measure received by patients and physicians radiofrequency estimate resultant somatic genetic risks.Radiation measured attempts at AV 31 consecutive Radiation using thermoluminescent sensors placed on patient...

Atrial fibrillation (AF) is a common comorbidity in bradycardia patients. Advanced pacemakers feature atrial preventive pacing and antitachycardia (DDDRP) managed ventricular (MVP), which minimizes unnecessary right pacing. We evaluated whether DDDRP MVP might reduce mortality, morbidity, or progression to permanent AF when compared with standard dual-chamber (Control DDDR).In randomized, parallel, single-blind, multi-centre trial we enrolled 1300 patients previous tachyarrhythmias, whom...

The goal of this study was to develop a risk score model for patients with Brugada syndrome (BrS).Risk stratification in BrS is significant challenge due the low event rates and conflicting evidence.A multicenter international cohort no previous cardiac arrest used evaluate role 16 proposed clinical or electrocardiogram (ECG) markers predicting ventricular arrhythmias (VAs)/sudden death (SCD) during follow-up. Predictive were incorporated into model, validated by using out-of-sample...

BACKGROUND Catheter ablation of accessory atrioventricular (AV) connections using radiofrequency current has been demonstrated to be effective in the majority patients with Wolff-Parkinson-White syndrome or paroxysmal supraventricular tachycardia involving a concealed AV connection. However, electrogram criteria have not established guide attempts at catheter ablation. METHODS AND RESULTS The characteristics local electrograms recorded successful and unsuccessful sites were determined 132...

We present the case of a 60-year-old woman with Brugada syndrome, permanent type 1 electrocardiographic pattern, who had previously received an implantable cardioverter-defibrillator. She suffered frequent syncopal episodes and multiple appropriate shocks (around five per month) due to polymorphic ventricular tachycardia/ventricular fibrillation, refractory quinidine therapy. Combined epicardial endocardial electroanatomical mapping was performed view substrate ablation. An area abnormal...

Ripple mapping (RM) is an alternative approach to activation of atrial tachycardia (AT) that avoids electrogram annotation. We tested whether RM superior conventional annotation based local time (LAT) for AT diagnosis in a randomized and multicenter study.Patients with were either or LAT using the CARTO3v4 CONFIDENSE system. Operators determined assigned 3D arm alone, before being permitted single confirmatory entrainment manuever if needed. A planned ablation lesion set was defined. The...
