Description
Summary:Neonatal enterovirus myocarditis is a rare but serious infection that is often an underrecognized cause of cardiovascular collapse. Enterovirus myocarditis in patients with such collapse should be suspected when signs of congestive heart failure and tachyarrhythmia are present. The majority of reported electrical disturbances associated with enterovirus myocarditis are ventricular in origin, but the infection can present as atrial tachyarrhythmia. Atrial tachyarrhythmias associated with enterovirus myocarditis are difficult to manage because of their resistance to conventional antiarrhythmic therapy. We present 2 cases of neonates with atrial tachycardia associated with enterovirus myocarditis who responded to a combination of amiodarone and flecainide.
