This condition is typically caused by cardiac injury; therefore, it is essential to evaluate whether there are any underlying cardiac issues and whether further diagnostic tests—such as an electrocardiogram (ECG) and serum troponin assay—are warranted. If troponin levels exceed the upper limit of normal by more than two-fold, this is likely indicative of myocardial injury. Additionally, consider whether the child has had a recent cold, respiratory infection, or diarrhea. A history of such illnesses significantly increases the likelihood of myocardial injury.
