title: Cardiac emergencies in children.
abstract: Pediatric cardiac emergencies require very specific treatment in the emergency room setting. Considering the possibility of a cardiac problem as the cause for the presenting symptoms is the initial step in successful management. Many patients present with what is initially considered a primary pulmonary disorder such as pneumonia, asthma, or bronchiolitis. Airway stabilization and ventilatory support, if needed, remain the first steps in stabilizing the patient. Many neonates with acutely decompensating heart disease may require the patency of the ductus arteriosus for survival. Prostaglandin E given as continuous infusion is the treatment of choice. Congestive heart failure can present at any age. In older patients, it is often due to myocarditis and is characterized by low cardiac output. Supportive measures, fluid restriction, and inotropic support are the basic concepts for initial treatment. Supraventricular tachycardia is a frequent arrhythmia, especially in young children. If the patient is unstable, immediate intravenous administration of adenosine or synchronized cardioversion are the initial interventions. In stable patients, vagal maneuvers may be attempted to abort the arrhythmia.
