Sophia just experienced heart block about an hour ago. This means that the electrical impulse from the atrium does not reach the ventricle. The lower part of the heart tries to take over and paces at 20-30 when a normal pace would be in the 70's or 80's. She had dropped to 60 and the nurse started a 12-lead EKG when she plummeted into the 20's. She was also in noticeable discomfort.
She is currently being paced by an external pacemaker. She had first degree AV block or PR prolongation (which is the precursor to heart block) when she first came out of the OR but was doing fine all throughout the night. The hypothesis at this point is that it's temporary and that she will get over this since she has a strong heart.
Keep those prayers coming! She can use them, so that she won't need a pacemaker. Meanwhile, mom is on the lookout for some good drugs for the adults.
I am not sure what any of this means, but I'm sure Astrid will explain it to me later!! Short story is that despite the drama, all continues to go well, and the prognosis is good.
