Unveiling the Uncommon: A Paediatric Case of Influenza-Related Atrioventricular Block

This case report highlights a 5-year-old child who developed a first-degree atrioventricular (AV) block during an influenza B infection. Influenza is a common viral illness that can cause severe morbidity and mortality, especially in children with underlying medical conditions. The case emphasizes the potential cardiac complications of influenza and the need for prompt recognition in paediatric patients. The child presented with bradycardia and a prolonged PR interval on the electrocardiogram, indicating AV block. The child had no other symptoms and was discharged in stable condition after two days of observation. Prompt recognition and evaluation of cardiac manifestations in influenza-infected patients, including thorough medical history and diagnostic workup, are crucial for the timely management and prevention of long-term sequelae. This case underscores the importance of considering cardiac complications in severe cases of influenza, especially in the paediatric population, and emphasizes the need for healthcare providers to be vigilant in identifying potential cardiac manifestations during influenza outbreaks.
