Pace Mapping for the Identification of Focal Atrial Tachycardia Origin
Focal atrial tachycardia (FAT) is a relatively uncommon form of supraventricular tachycardia that is difficult to treat with antiarrhythmic drugs (AADs). However, with the advent of radiofrequency catheter ablation (CA), this tachycardia can be treated with a high long-term success rate. The key aspect of successful ablation is to localize the site of the earliest site with and without 3-dimens...
متن کاملCharacterization of focal atrial tachycardia using high-density mapping.
OBJECTIVES The goal of this study was to characterize the origin of focal atrial tachycardias (AT). BACKGROUND Focal ATs originate from a small area and spread centrifugally; however, activation at the AT origin has not been characterized. METHODS Twenty patients with AT having failed prior ablation or occurring after atrial fibrillation ablation were studied. After excluding macro-re-entry...
متن کاملFocal atrial tachycardia.
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 su...
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...
متن کاملthe effect of taftan pozzolan on the compressive strength of concrete in the environmental conditions of oman sea (chabahar port)
cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
