“…Idiopathic ventricular tachycardia originating from the left ventricle (ILVT), especially sustained ventricular tachycardia characterized by a QRS with right bundle branch block and left axis deviation, forms a distinct clinical entity 1–8 . Idiopathic ventricular tachycardia originating from the left ventricle is responsive to verapamil and pharmacologic therapy, consisting mainly of verapamil, has been used.…”

B Ba ac ck kg gr ro ou un nd d: Idiopathic sustained ventricular tachycardia originating from the left ventricle (ILVT) has been an indication for catheter ablation. The present study evaluated the clinical features, long-term prognosis and indications for treatment in pediatric patients with ILVT. M Me et th ho od ds s: The subjects of the present study were eight patients (four males and four females) with a mean age at onset of 11.0 years (range 3-15 years). The mean follow-up period was 7.7 years (range 2.1-11.3 years). R Re es su ul lt ts s: In electrophysiologic studies, intravenously administered verapamil was effective for the termination of tachycardia in all six patients who received this treatment and for the prevention of tachycardia in four of five patients. Oral administration of verapamil was effective in five of seven patients. Propranolol or flecainide was added to the treatment protocol for two patients who did not respond to verapamil alone. Tachycardia disappeared without drugs in four patients during the follow-up period and became nonsustained in another patient. Two of three patients with persistent tachycardia underwent catheter ablation. Pharmacologic treatment was very effective for ILVT among these patients. C Co on nc cl lu us si io on ns s: Pharmacologic therapy, such as with verapamil, is still the treatment of choice for ILVT because of a good long-term prognosis and potential risks and complications by manipulation of catheter ablation.

“…Most forms of outflow tract VTs are adenosine-sensitive and are thought to be mediated by catecholamine-induced, delayed after depolarizations (DADs)-induced triggered activity [9][10][11]. Although the prognosis of outflow tract ectopy is considered to be good [12][13][14][15][16][17], rapid polymorphic VT (PVT) and/or ventricular Journal of Cardiovascular Emergencies 2015;1(2):65-67 fibrillation (VF) are occasionally initiated by RVOT PVCs [18,19].…”

Ventricular arrhythmias (VAs) in patients without structural heart disease can be found in a significant portion of the general population. The prognosis of patients with idiopathic VA is usually favorable and patients are often asymptomatic. However, sudden cardiac death (SCD) as a consequence of idiopathic VA has been reported. The aim of this review is to present an overview of the association between idiopathic VA and SCD.

“…In patients who continue to have VT despite medical therapy with b-blockers or calcium channel blockers, class I or class III anti-arrhythmic therapy may be effective [1,58]. Medical therapy may be ineffective in many patients, and for these patients catheter ablation may be the appropriate next step as it carries a high chance of success with minimal intra procedural risk [59][60][61].…”

Ventricular tachycardia (VT) in patients without structural heart disease can be observed in 10% of patients presenting with ventricular arrhythmias. These VTs are characterized by QRS morphology, ventricular origin and their response to pharmacologic agents. It is essential to rule out structural heart disease in this population as this can significantly alter the management and the long-term prognosis. These VTs generally have a benign course and therapeutic options are aimed at relieving symptoms related to the arrhythmia. Medical therapy is effective in many patients and radiofrequency offers a cure to those who are refractory to medical therapy. Careful attention to the electrocardiogram can help localize the origin of the VTs, which is crucial when planning an ablation strategy.
