title: [Chaotic atrial tachycardia-induced cardiomyopathy: report of an isolated case].
abstract: Chaotic atrial tachycardia is a rare arrhythmia that has no known etiology and that usually inflicts upon newborn infants. The diagnosis is established using the surface electrocardiogram (ECG) which shows a spectacular polymorphism and irregularity of the atrial electrical activity. Clinical tolerability is variable depending on the ventricular rhythm. Cases that are not well tolerated and cases who do not recover spontaneously require medical treatment which relies mainly on amiodarone and other class IC anti-arrhythmic drugs. There is usually complete recovery during the first few months of life. The authors present the case of a female patient who was diagnosed with chaotic atrial tachycardia with induced cardiomyopathy following birth. She was successfully treated with amiodarone but had several relapses of the arrhythmia upon discontinuation of the drug. Although this observation is classic in its presentation, we consider that it is useful to remember this rare and frequently forgotten syndrome and to report the unique and particular aspects of our case and its evolution.
