My daughter had SVT when she was a month old.
After a couple of Army doctors did a three stooges impersonation trying to diagnose why she wasn’t eating and was dehydrated (looking suspiciously at us of course), through a stroke of luck we stumbled onto one military doctor who knew what to do. She put ice on her face to stop the SVT episode, and put her on a Blackhawk to the nearest NICU. This doctor was a life saver and a miracle.
We had to give her medicine for a year and a half (not easy with a newborn), and monitor her heartbeat twice a day.
Praise the Lord indeed!
