“…The location of the arrhythmia within the RV was identified in the manor described by Josephson and listed in the table as "Josephson area." 9 The indications for catheter ablation are listed in the Table. The indication for ablation in 7 patients was a clinical history of palpitations with documented VT. In 2 patients (patients 4 and 8), the ablation was indicated due to frequent premature ventricular contractions (PVCs) and nonsustained VT that led to a PVC-or tachycardia-induced cardiomyopathy with mild or moderately decreased function.…”

“…If symptomatic or associated with left ventricular (LV) dysfunction, the VPBs can be treated conservatively with antiarrhythmic drugs (AADs) 4,5 ; however, drug therapy may predispose to recurrence and is associated with risks including proarrhythmia. Catheter ablation has been reported to be efficacious at VPBs suppression [6][7][8][9][10] and to improve cardiac function in patients with high VPB burden. [8][9][10] Few reports, however, have compared the effects of AADs and radiofrequency catheter ablation (RFCA).…”

a total of 513 consecutive patients who were referred to the Second Affiliated Hospital of Chongqing Medical University for treatment of RVOT VPBs were © 2014 American Heart Association, Inc. Original ArticleBackground-The purpose of this study was to compare the efficacy of radiofrequency catheter ablation (RFCA) versus antiarrhythmic drugs (AADs) for treatment of patients with frequent ventricular premature beats (VPBs) originating from the right ventricular outflow tract (RVOT). Methods and Results-A total of 330 eligible patients were included in the study and were randomly assigned to RFCA or AADs group. The absolute number and the burden of VPBs on 12-lead Holter monitors were measured at baseline and at 1st, 3rd, 6th, and 12th months after randomization. Left ventricular eject fraction was evaluated by transthoracic echocardiogram at baseline and at 3 and 6 months after randomization.

“…The valvular aspect of the right ventricle accounts for about half of all idiopathic non-outflow tract, right ventricular tachycardias 42. Tricuspid origins are located preferentially at the septal portion of the annulus, although anteroseptal tricuspid annular tachyarrhythmias may overlap with parahisian exhibiting a right-sided exit 43…”

Idiopathic ventricular arrhythmias occur in the absence of underlying structural heart disease and less commonly in the presence of coexistent, but mechanistically unrelated, myocardial scar. These arrhythmias originate from several anatomical sites in both ventricles, with a predilection in outflow tract structures. The 12-lead surface ECG is the initial mapping tool, which is widely used to identify their origin. Specific features can predict the site of idiopathic ventricular arrhythmias, thus differentiating right from left ventricular, as well as endocardial from epicardial origins. In this review, we aim to analyse electrocardiographic landmarks for determination of idiopathic ventricular arrhythmia sources, with specific emphasis on pertinent caveats and anatomical relationships.
