Overview
There is no established screening method for atrioventricular block.
Screening
- Ambulatory electrocardiographic monitoring is useful for finding intermittent atrioventricular block, LBBB and bifascicular block in asymptomatic patients.
- In patients with symptomatic atrioventricular block or bradycardia during sleep, screening about sleep apnea is recommended.[1]
- Screening for congenital complete heart block is recommended in pregnant women with Ro/SSA antibodies.[2]
- Women with history of neonatal lupus, fetal echos are recommended weekly or every other week from week 18 to 28.
- It is unclear how often first degree heart block progresses to complete heart block, some cases my revert to normal sinus rhythm or complete heart block.
| 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 |
| (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[3] |
