ABSTRACT

We present the case of a nine year-old girl, previously healthy, attended in the emergency department for acute neurological complaint of 24 hours evolution, consistent with cerebellitis (fever, ataxia, tremors, dysdiadochokinesia), without evidence of heart failure. Electrocardiography showed changes suggest viral myocarditis probably with severe injury to conduction system manifested by right bundle branch block, with fast progression to second-degree atrioventricular block that recovery with steroid bolus. She was sent to tertiary pediatric center outcome to lethal arrhythmia. Echocardiography and resonance magnetic imaging allow a more acute diagnostic. Complex molecular interactions between viruses and host immune response mediated pathophysiology therefore immunoglobulin IV and interferon are promissory treatments. Myocarditis is a big challenge diagnostic by high risk of mortality and severe chronic cardiac sequels. Electrocardiography remains as a highlight diagnostic tool within emergency room.
