Remember when Ellyson was a newborn and Jack fainted while driving, causing a near-fatal car accident? As most of you have heard by now, he had a repeat episode this week. Thankfully, he was on a smaller road, where he could quickly pull over and lie flat. So he did not pass out, and did not have an accident. Otherwise, the "event" mimicked the previous one. The nausea, lightheadedness, and drenching cold sweat that preceded his fainting spell was a repeat of before.
Eventually, we got him to the hospital (it was only in retrospect that the episode really started to seem significant, especially considering his cardiologist couldn't see him for another week).
We spent Wednesday night in the emergency room. I left around 1:30 a.m., once Jack was settled into an observation room for the night. They ran multiple EKGs, drew blood three or four times, took a chest x-ray, and did an echocardiogram which is basically an ultrasound of the heart (it shows scar tissue, valve/chamber function, etc). All were normal. Just like every single time before.
The cardiologist is confident now that he's having vasovagal episodes. These are episodes where an environmental trigger (for some people it could be needles, blood, pain, certain drugs, etc) causes the vagus nerve to interrupt normal function and decrease the heart rate until the body faints. It is a condition that was considered in 2011, but couldn't be confirmed. A positive tilt-table test confirms diagnosis - but Jack's was negative in 2011, which doesn't rule out the condition, it just fails to confirm it. They've ruled out cardiac episodes or malfunction because they see the valves are working properly, a heart rate monitor shows no irregularities, and the echo shows no scar tissue. As we follow up with his cardiologist, we will go over more tests and possible treatments to help prevent another episode. We do know two ladies at our church who have this condition, and are using different methods to manage it, so it is nice to have their perspectives.
Until we can prevent it, we just keep praying he won't have another (or will be in a place where he can quickly pull over).
