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.

Diagnostic Study of Choice

Study of choice

Electrocardiography (ECG) is employed to determine the type of second-degree atrioventricular (AV) block present^[1]^[2]^[3].
Follow-up ECGs and cardiac monitoring are appropriate^[4].
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.

Name of Diagnostic Criteria

There are no established criteria for the diagnosis of AV block.
