Why the study?
Atrioventricular blocks rarely develop in patients with myocarditis, prompting this report of a patient who developed second-degree high-grade atrioventricular block after myocarditis.
Highlights a rare case of transient second-degree high-grade AV block complicating myocarditis with complete recovery following treatment.

Transient high-grade AV block may complicate pediatric myocarditis; case report leaves open optimal monitoring duration and recurrence risk.
Myocarditis is an inflammatory disease of the heart muscle that most commonly occurs after infectious diseases in childhood. The clinical picture of acute myocarditis ranges from asymptomatic infection to fulminant heart failure and sudden death (1). Most of the patients may present with nonspecific symptoms such as respiratory distress, chest pain, nausea, and vomiting (2). While rhythm abnormalities such as ventricular and supraventricular rhythm disorders can be observed in these patients, various degrees of atrioventricular blocks may rarely develop (3). In this article, we aimed to present a patient who developed second-degree, high-grade atrioventricular block after myocarditis and recovered completely after treatment.
