Sick sinus syndrome was disclosed in a 77 year-old man after a radiofrequency (RF) linear catheter ablation of cavotricuspid isthmus for persistent common atrial flutter. Prolongation of corrected sinus node recovery time, sinoatrial conduction time and AH interval, as observed after RF ablation, suggested binodal (sinus as well as atrioventricular node) dysfunction. Adams-Stokes syndrome due to sinus arrest was encountered on the day of RF ablation and a permanent DDD pacemaker was implanted consequently. Our experience indicates that careful observation is very important after the RF ablation when atrial flutter is associated with sick sinus syndrome. The present case suggests that binodal dysfunction underlies persistent atrial flutter and vice versa.

This case report discusses the management of a 75-year-old man who developed an unusual type of atypical atrial flutter following a previous pulmonary vein isolation for paroxysmal atrial fibrillation. Despite a second attempt to re-isolate the pulmonary veins and performing cavotricuspid isthmus ablation (which was suspected to be part of the arrythmia circuit), the flutter continued and was converted to sinus rhythm through electrical cardioversion. A few weeks later, the patient's atrial tachycardia relapsed.

Background: Although catheter ablation (CA) by mean of pulmonary vein isolation (PVI) is nowadays the mainstay treatment for atrial fibrillation (AF), its success-rate in persistent AF remains suboptimal. Results from studies evaluating whether adding posterior wall isolation (PWI) to PVI can increase the success-rate of CA in persistent AF have yielded conflicting data. The aim of this meta-analysis was to assess whether PWI plus PVI might be beneficial in patients with persistent AF.

Background: Detection of atrial tachyarrhythmias (ATA) on long-term electrocardiogram (ECG) recordings is a prerequisite to reduce ATA-related adverse events. However, the burden of editing massive ECG data is not sustainable. Deep learning (DL) algorithms provide improved performances on resting ECG databases.

Aim And Background: To assess the efficacy and safety of Ibutilide infusion for cardioversion of atrial fibrillation (AF) or flutter (AFL) to sinus rhythm.
Materials And Methods: This open-label, multicenter phase IV study was conducted at six sites across India. The study enrolled 120 patients (108 with AF, 12 with AFL), each receiving up to two, 10-minute intravenous doses of 1.

Background: Radiofrequency ablation (RFA) procedures including cavo-tricuspid isthmus (CTI) ablation have proven to be safe and effective therapies for the treatment of many cardiac tachyarrhythmias. The incidence of coronary arterial injury (CAI) associated with RFA including CTI ablation is estimated to occur in <0.1% of patients.
