Overview

Electrocardiography (ECG) is employed to determine the type of second-degree atrioventricular (AV) block present. Follow-up ECGs and cardiac monitoring are appropriate. Routine imaging studies are not required. However, if myocarditis is a concern, echocardiography may be indicated. If myocardial ischemia is a concern, a chest radiograph may be indicated.
