Spontaneous brain arteriovenous malformation rupture with atrioventricular block in a pediatric patient.

This case reports 9 year-old-female with atrioventricular block and seizure. Careful evaluation, including electrocardiogram (ECG) and computerized tomography (CT) revealed a high-grade atrioventricular block and spontaneous brain arteriovenous malformation (AVM) rupture. The patient had complete resolution of her bradycardia and AV block following atropine. This case is to our knowledge the first description of a pediatric spontaneous brain AVM rupture presenting with high degree AV block responsive to intravenous atropine.
