Clinical Implication of Multifocal Atrial Tachycardia in Children for Pediatric Cardiologist

Multifocal atrial tachycardia in 2 children.

The incidence of multifocal atrial tachycardia (MAT) is very low and accounts for less than 1% of supraventricular tachycardia in infants and children. In this report, the clinical characteristics, medical treatment and outcome of MAT in 2 children are described. The first patient presented with tachycardia and respiratory failure since the day after birth. First, he received amiodarone, propra...

Multifocal atrial tachycardia in two neonates.

Two neonates with rapid and irregular pulse rate had an uncommon form of atrial tachycardia. The irregular heart rate was first detected during fetal monitoring. Postnatal electrocardiograms were compatible with the diagnosis of multifocal atrial tachycardia or chaotic atrial rhythm. Both patients were treated with digoxin and the rhythm gradually reverted to sinus. This may represent the first...

The Complexity of Pediatric Multifocal Atrial Tachycardia and Its Prognostic Factors

BACKGROUND AND OBJECTIVES Multifocal atrial tachycardia (MAT), in general, has a favorable outcome. However, there are insufficient data regarding MAT in a pediatric population. This study sought to determine the clinical course of MAT and identify potential prognostic factors. METHODS The medical records of MAT patients from 1997-2015 were reviewed. The arrhythmia control rate and factors fo...

Ectopic atrial tachycardia in children.

BACKGROUND AND PURPOSE Ectopic atrial tachycardia (EAT) is an unusual and potentially risky arrhythmia that can result in left ventricular dysfunction if not properly managed. In adults, EAT is mainly caused by diseased atrial myocardium and responds poorly to antiarrhythmic drugs. The characteristics of EAT in children might be different from those in adults because of their immature myocardiu...
