A 3-months-old infant was urgently admitted for drowsiness and lack of appetite started 24 h before. The ECG showed sinus rhythm with a prolonged AV interval (200 ms) and very large QRS complexes (280 ms) due to Flecainide overdosing following incorrectly administration for poor communication between parents resulted in both giving a dose to the infant. Flecainide serum level was 1.2μg/ml, confirming the diagnosis of an accidental drug intoxication. The patient started continue hydration with a close monitoring. Three hours later a significant narrowing of the QRS complex (150 ms) was observed, then over the following 24 h, the QRS almost completely normalized.

Abstract
A 3-months-old infant was urgently admitted for drowsiness and lack of appetite started 24 h before. The ECG showed sinus rhythm with a prolonged AV interval (200 ms) and very large QRS complexes (280 ms) due to Flecainide overdosing following incorrectly administration for poor communication between parents resulted in both giving a dose to the infant. Flecainide serum level was 1.2μg/ml, confirming the diagnosis of an accidental drug intoxication. The patient started continue hydration with a close monitoring. Three hours later a significant narrowing of the QRS complex (150 ms) was observed, then over the following 24 h, the QRS almost completely normalized.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
