Overview

There is insufficient evidence to recommend routine screening for first degree AV block. However, screening for congenital AV block is recommended.

Screening

• Ambulatory electrocardiographic monitoring is useful for detection of intermittent atrioventricular block, LBBB and bifascicular block to in asymptomatic patients.
• In patients with symptomatic atrioventricular block or bradycardia during sleep, screening about sleep apnea is recommended.
