The cardiologist explained that Barrett's heart apparently didn't respond as well as he hoped to the oral heart medicine. So now, he is putting him on a bigger, stronger medicine that should keep his heart under control. It will take the new medicine about 5-8 days to "load" into Barrett's system before it will be effective. We'll be in the ICU for a while until the doctor sends us home on a loading dose of an oral version of the new medicine, in addition to the old medicine. Thankfully, Barrett's condition is not as critical as the last stay in ICU because he was not in SVT long enough to put him into cardiomyopathy.
Right now, we are supposed to go home tomorrow. I have to say, I'm nervous to leave the ICU because I've become pretty reliant on looking at the machines and monitors to constantly check his heart rate...
Here's a picture of Barrett hanging out in his bouncer -- we scooted it up to his mini-hospital bed so that his IV cords could reach.
Here he is propped up in his boppy in the hospital bed.
