Atrial ectopic tachycardia (AET), a type of supraventricular tachycardia, is often difficult to differentiate from sinus tachycardia. This article provides information on how to make this important distinction and offers a relevant case report of a 12-year-old boy who was diagnosed with mild congestive heart failure as a result of an exacerbation of ...

Atrial Ectopic Tachycardias/Atrial Automatic Tachycardia
2006Disorders of impulse formation account for approximately 10% of the tachycardias in infants and children. These include automatic atrial tachycardia (AAT), also known as ectopic atrial tachycardia (AET), originating from a single focus in the atrium, multifocal atrial tachycardia (MAT, or chaotic atrial tachycardia) thought to arise from multiple foci ...

Multifocal Atrial Tachycardia and Ibutilide
The American Journal of Geriatric Cardiology, 2001Multifocal atrial tachycardia is an electrocardiographic phenomenon seen primarily in the elderly. The hemodynamic consequences of multifocal atrial tachycardia in an elderly woman are presented. Successful treatment with Ibutilide is demonstrated.

Verapamil and Multifocal Atrial Tachycardia
Annals of Internal Medicine, 1988Excerpt To the editor: Although Salerno and coworkers (1) suggest intravenous verapamil may be effective for the treatment of multifocal atrial tachycardia, several notes of caution should be sound...

Simultaneous atrial and nodal tachycardia
American Heart Journal, 1957Abstract A case of simultaneous atrial and nodal tachycardia, probably due to digitalis intoxication, is reported. Recovery occurred following the intravenous infusion of potassium chloride. The evolution of the atrial rhythm was similar to that which occurs in digitalis-induced atrial tachycardia with block.

Chaotic atrial tachycardia in childhood
American Heart Journal, 1981Ten cases of chaotic atrial tachycardia (CAT) in childhood are reported. Patients' ages ranged from 1 day to 18 years (average, 3.5 years) at the time of diagnosis. The patients were divided into groups according to the following criteria: (1) no cardiac disease (n = 5), (2) congenital heart disease (n = 4), and (3) acquired heart disease (n = 1). Nine

Contemporary approach to treat atrial tachycardias requires almost always a 3D mapping system to find the origin of atrial foci; this allows to easily reduce or to eliminate the need of fluoroscopy to approach these targets. We describe the approach to minimal or no fluoro cases while performing atrial tachycardia ablation.

Focal atrial tachycardia (AT) demonstrates an activation pattern with a centrifugal activation from a small area (focus or origin of the tachycardia). The inducibility and response of AT to catecholamines depend on the mechanism of the AT, such as abnormal automaticity, triggered activity, and localized reentry.

Multifocal atrial tachycardia (MAT; also known as chaotic atrial tachycardia) is an unusual arrhythmia in children. The defining characteristics—P-waves of three or more distinct morphologies with irregular P–P intervals, an isoelectric baseline, and an atrial rate greater than 100 beats per minute—are the same as those in adults.
