Rotavirus enteritis in children: serum myocardial enzyme spectrum detection and analysis. Clear increase in myocardial enzyme activity, indicating that rotavirus infection can cause myocardial damage; also, varying degrees of dehydration are observed in the RV enteritis group. The moderate dehydration group shows a significant increase in serum myocardial enzyme activity, suggesting that the degree of myocardial injury is closely related to the severity of the disease. Based on the above information, serum myocardial enzyme activity can be used as an important index for monitoring the condition and prognosis of children with rotavirus enteritis. In treatment, we can use vitamin C, coenzyme Q, and energy mixtures to assist with antiviral therapy and improve blood circulation. Additionally, timely correction of dehydration, acidosis, and electrolyte disorders can also improve myocardial injury caused by rotavirus infection, which is one of the important measures. In clinical cases of rotavirus enteritis in children with myocardial injury, symptoms are often mild and easily overlooked. Therefore, early screening of myocardial enzymes in children, early diagnosis, and timely and accurate treatment are necessary.
