Focal atrial tachycardia.

چکیده
Focal atrial tachycardia is a relatively uncommon arrhythmia. Nevertheless, the management of highly symptomatic patients with focal atrial tachycardia can be problematic owing to the poor response to medical treatment. Moreover, focal atrial tachycardia can trigger other atrial arrhythmias like atrial fibrillation and flutter. Radiofrequency ablation of focal atrial tachycardia is extremely successful and this approach is becoming the preferred treatment for symptomatic patients.In this review, we describe the pathophysiology, anatomical localisation, clinical features, diagnosis and therapeutic options for the management of focal atrial tachycardia.

Atrial tachycardia: mechanisms, diagnosis, and management.
Atrial tachycardia is an uncommon arrhythmia and may be focal or macroreentrant. This review concentrates on focal atrial tachycardia. Over the last decade there have been a number of advances in delineating the mechanism and anatomic locations of focal atrial tachycardia. The lack of efficacy of antiarrhythmic therapy and the advent of radiofrequency ablation have altered our primary approach ...
متن کاملAblation of focal atrial arrhythmia in patients with congenital heart defects after surgery: role of circumscribed areas with heterogeneous conduction.
BACKGROUND In patients late after surgical repair of congenital heart disease (CHD), areas with abnormal electrophysiologic properties may serve as slow conducting pathways within a macroreentrant circuit or may be the source of focal atrial tachycardia. OBJECTIVES The purpose of this study was to evaluate the role of abnormal areas during focal atrial tachycardia prior to ablation. METHODS...
متن کاملInadvertent isolation of a focal tachycardia within the superior vena cava
The superior vena cava (SVC) is known to be a potential source of focal atrial tachycardias. Not uncommonly these tachycardias trigger atrial fibrillation or flutter. Focal ablation is safe and effective in eliminating arrhythmogenic foci within the SVC. We present the case of a patient with focal atrial tachycardia arising from the SVC. During presumably focal ablation inadvertent electrical i...
متن کاملSocial anxiety provoked by speech-induced atrial tachycardia
Introduction Focal atrial tachycardia (AT) mechanisms include enhanced automaticity and triggered activity. Autonomically mediated focal atrial arrhythmias (AT or atrial fibrillation [AF]) are rare. Adrenergic stimulation such as exercise or stress can initiate focal atrial arrhythmias by enhancing automaticity, whereas vagal nerve arrhythmogenicity is associated with reentry and early afterdep...
متن کاملFocal atrial fibrillation presenting in the origin of atrial tachycardia
Introduction The preferential origin of atrial tachycardia (AT) is generally associated with specific anatomical atrial structures such as crista terminalis, tricuspid annulus, mitral annulus, and pulmonary veins. There are 3 major mechanisms of focal AT: enhanced automaticity, triggered activity, and microreentry. Focal AT can be eliminated via radiofrequency ablation with fairly good long-ter...
