The wheezer that wasn't.

The expression of cardiac dysfunction in pediatric patients with myocarditis may not be conspicuous. While older children with myocarditis may abruptly present with pleuritic or angina-like pain, infants and toddlers with fulminant disease are unable to verbalize such complaints. Cardiac compromise in preverbal children may only be inferred from variable examination findings that include gallop rhythm, tachycardia, malignant dysrhythmias, murmur, rub, and signs of congestive heart failure. The emergency physician is likely to overlook a cardiac origin for wheezing in a child with a past medical history of asthma. Therapeutic modalities chosen for reactive airway disease may adversely influence the outcome of a patient with myocarditis.
