Overview

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

Recommendations for screening sleep apnea in patients with bradycardia or conduction disorder

(Class I, Level of Evidence B):

❑ Screening about sleep apnea syndrome is recommended In patients with documented or suspected bradycardia or conduction disorder during sleep
❑ Continuous airway pressure and weight loss is recommended in patients with bradycardia or conduction disorder during sleep and documented obstructive sleep apnea

(Class IIa, Level of Evidence B):

❑ In patients with previously PPM implantation for bradycardia or conduction disorder, screening about sleep apnea syndrome is reasonable

The above table adopted from 2018 AHA/ACC/HRS Guideline^[2]
