2024年10月8日 · Focal atrial tachycardia (FAT): Consistent, abnormal P wave morphology indicating an ectopic focus. The term FAT is commonly used synonymously with atrial tachycardia, a broader term referring to any form of SVT …

2024年6月4日 · Focal atrial tachycardia (focal AT) is characterized as a rapid regular rhythm arising from a discrete area within the atria. It occurs in a wide range of clinical conditions, including catecholamine excess, digoxin toxicity, congenital heart disease, and cardiomyopathy.

2023年6月26日 · A focal atrial tachycardia is an arrhythmia with electrical impulses originating and confined within the atria. Focal tachycardia typically occurs in the setting of increased metabolic demand and stress, like infection, hypoxia, etc. Focal …

2022年8月4日 · Atrial tachycardia has two types: Focal. This kind of atrial tachycardia starts in a specific location (focus) on your heart. It’s usually not dangerous. However, it can be if it continues over a longer period. In some cases, there can be more than one focus. This is called multifocal atrial tachycardia.

Atrial tachycardia is defined as a regular atrial activation from atrial areas with centrifugal spread, caused by enhanced automaticity, triggered activity or microreentry. New ECG classification differentiates between focal and macroreentrant atrial tachycardia.

2019年2月22日 · Focal atrial tachycardia (AT) is characterized by atrial activation starting at a small area (focus), from which it spreads out centrifugally. “Focal” implies that the site of origin cannot be mapped spatially beyond a single point or a few adjacent points with the resolution of a standard 4-mm-tip catheter.

Focal atrial tachycardia occurs in the settings of structurally normal heart, coronary artery disease, congestive heart failure, cardiac surgery, catecholamine ingestion, digoxin toxicity, and alcohol dependency. Symptoms and signs include palpitations, …

Atrial tachycardia (AT) may be focal or macroreentrant. In this review we will concentrate on focal AT. The diagnosis of focal AT may be made from a standard electrocardiogram (ECG); however, in some cases differentiation from other forms of supraventricular tachycardia may be difficult.

Atrial tachycardia tends to occur in individuals with structural heart disease, with or without heart failure, and ischemic coronary artery disease.However, focal atrial tachycardia often occurs in healthy individuals without structural heart disease.Other possible etiologies are listed below: [2] …

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.
