Study finds low anti-Ro titers are not associated with fetal heart block

Types of AV block
- Early damage (first-degree AV block): The signals that control the heartbeat are delayed, but fetal heart rate and rhythm are normal.
- Evolving damage (second-degree AV block): Electrical signals are partially blocked, and the fetal heart rhythm is irregular.
- Complete damage (third-degree AV block): Electrical signals within the heart are completely blocked and the fetal heart rate is slow.
