18 Week Fetus diagnosed with SVT

Baj

My little one got flagged up for having a consistent HR of 200 and subsequently is diagnosed with SVT. I've been prescribed medication to get the baby's HR to a normal pace.

Anyone else going through a similar situation? Its rare and there doesn't seem to be many posts about fetal SVT but more so about adult SVT.

Any discussions or context I would appreciate. Thanks!
