ECG features in children with respiratory difficulty syndrome

Acute and chronic nonspecific lung diseases arc one of the most important urgent problems of pediatric pulmonology. Dysfunction of the cardiovascular system is often accompanied by complicated pneumonia in children and develops from the first hours; at the same time, circulatory disorders, unlike in adults, from complications of the underlying disease and determine its outcome. These changes are diverse and depend on the severity of the underlying disease, the patient's age, and the premorbid background. According to scientists, carditis in young children, as a complication of acute myocardial infarction, occurs in 4% to 23% of cases. Diagnosis of the disease is difficult due to the lack of clear clinical manifestations, ranging from minimal changes in the ECG to cardiogenic shock and sudden death.
