Gage woke up crying at about 12:30 tonight. He was very upset and Kristy noticed something wasn't right. With her hand over his heart she could tell immediately that he was in SVT. We got out the stethoscope and confirmed it. His little heart was beating so fast we couldn't even count it. When Gage stopped crying and there was silence for a moment I could hear his mechanical valve racing even with my ear inches away from his chest.
By my count I got 21 beats in the first four seconds. I couldn't keep up. Do the math though and it's about 315 beats per minute. Not his record high if I recall but higher than he's seen in a while. I had just given him his dose of Sotalol at 11pm. It's been the only drug capable of controlling the SVT up until tonight it seems.
Kristy is taking him to the E.R. now.
