I have two things to blog about, both about Christopher. I'll save the fun one for last.
Thing One:
Normally I would put the end of the story at the end of the story, instead of the beginning, but in the interest of not causing undue worry I'll say the end right now: Christopher is more or less fine.
So here's the rest of the story.
Last Wednesday I took Chris to his doctor for a well check and Kindergarten shots. When the doctor got to the part where he was listening to Christopher's heart, he furrowed his brows and listened some more.
And some more.
Then he had Chris take a deep breath. Then he listened while Chris was lying down.
None of this was the kind of thing a mother wants to see. But I kept my cool and waited.
He finally told me he heard a faint heart murmur. He said he thought it was probably what's known as an "innocent murmur," but he would prefer a pediatric cardiologist check it out to be sure.
A little worrying, I'll admit, but most of me knew Chris would be okay. I'm actually proud of myself for not working myself into a panic about this. I decided to assume the best (or try to) until I heard otherwise.
Thursday we went to see the pediatric cardiologist. First thing the nurse did was take his blood pressure (which Christopher LOVED!) and then hook him up to an electrocardiogram. That's that thing where they hook a bunch of wires to your chest to create a big printout with your heartbeat, etc on it.
Then the doctor came in and talked to me about this printout. He said his heart is beating normally, with good rhythm, etc, but that it showed something that has nothing to do with a heart murmur. He said it showed that there is a problem with his "wiring." He said, let me take a listen to his heart and then we'll talk more.
Okay.
So he listens to his heart and confirms that the murmur is innocent. He can hear the blood going into one of the upper chambers and out of one of the lower ones, but that's not a problem. No worries.
Now back to the wiring. He draws me this little picture, explaining things as he draws:

I'm going to go ahead and explain everything he explained to me, for those of you who are interested in these kinds of details.
He starts with just the heart shape ("the highly anatomically correct heart shape" he says) and divides it in half lengthwise. The heart has left and right chambers, and also upper and lower chambers on each side.
Blood flows into the upper chambers (see handy arrow flowing into upper left quadrant) where the blood collects, and then it gets pumped into the lower chambers, and then pumped out of the lower chambers. The lower right chamber pumps blood to the body. The lower left chamber pumps blood to the lungs, through that T-shaped artery.
With me so far? Okay. So in the upper left chamber, he put a star. This is the pacemaker. It's job is to send an electric current out, which makes the heart pump. The curved lines going down and away from the pacemaker show where that wave of electricity goes. The electricity wants to go to the lower chambers too, but there's a thick (I forget if he said mucus or what) but a thick thing that stops that current from going to the lower chamber in big waves the way it goes to the upper chamber in big waves. The yellow line represents that thing that blocks the electrical current.
(Side note: Even though the mommy in me is a little freaked out because he's getting ready to tell me what's wrong with my little boy's heart, the curious part of me found it fascinating to hear more about how the heart works. It really is amazing, and I'm in awe of the kind of people who can figure it out. I mean, how in the heck do they figure out how electricity flows through the heart??? But I digress...)
Okay, so the way the electrical current gets to the lower chambers is through the area in the middle, represented by that big black oval. See how he drew a line, in the lower right chamber, from the black oval, around the wall of the chamber and back up? That's the normal flow of electricity in each chamber, causing the lower chambers to pump, again stopped by the yellow line. Once it gets to that yellow line, the heart stops cold. Then the pacemaker sends out another signal and it starts again. That's how the heart pumps: upper, lower, stop... upper, lower, stop.
Cool, yes?
Okay, so that's all how the heart normally works. In Christopher's case, there's an extra electrical path somewhere. For the sake of example, the doctor drew that thick black arrow, outside the heart shape, on the left hand side. That represents Christopher's extra pathway, though the pathway could be anywhere, and in fact I later saw an illustration online that showed an extra pathway inside the chambers.
Anyway, he said when the pacemaker sends out it's signal, electricity is going the normal way, but also following that extra pathway to the lower chambers. Because of the way electricity works, that electric signal is met by other electrical path coming back up the chamber, and so the "circuit is closed" and the flow stops there. Therefore, that normal electrical path in the bottom chamber is stopped from flowing back up the extra pathway into the upper chamber.
This is hard to explain without being able to point to the drawing.
Anyway, if for some reason electricity does NOT go down that extra electrical path, that means the circuit is open and when electricity is coming from the lower chamber to the upper chamber, it has an open pathway up to the upper chamber, instead of being stopped completely by that yellow line. That electricity will then reach the pacemaker, which will overstimulate it, causing an extremely rapid heartrate. We're talking 250 to 270.
So, as long as electricity is always going from the pacemaker down that extra path, there's no problem. If for some reason it doesn't, it will flow up and Chris will get that rapid heartrate. That can last anywhere from a few seconds to a few hours.
Now, the doctor and I both asked Chris a couple different times if he's ever felt his heart beating super fast. He said no every time. The doctor said he may never feel symptoms, and will probably eventually grow out of it.
To make sure there were no other problems with his heart, they did an echocardiogram (basically an ultrasound but for his heart). That took awhile, because the heart is a complicated organ that's always on the move, so it takes awhile to get measurements, check all the different angles, etc. It was interesting to watch. The lady doing it was good about explaining things to me. When I said, "how do they figure things like this out?" she said, "I think the Big Guy Upstairs figured it out." :) Yes, I agree. And it's only one of about a billion absolutely amazing things he's done. Then I said, "Yeah, but how do people here figure out what He did?" I don't know, but it's good that crazy smart people like that are in medicine. It's a good way to use the gifts God gave them.
Anyway, waiting for the doctor to tell me the results of the echocardiogram was the worst aprt. That's when I started to wonder if there wasn't something desperately wrong. But fortunately it showed there are no structural problems with his heart, no holes, etc. Thank goodness.
So here's what the doctor said about this extra electrical path, which is known as Wolff-Parkinson-White or WPW Syndrome. He said Chris may start having symptoms (that rapid heartbeat). If he does, we don't need to worry. Even though it's not good for the heart to be that overworked, obviously, this isn't an issue of him dropping dead or something.
Good. To. Know.
The doctor wants to see Chris in a year to see how he's doing. If Chris has, say, one episode a month, that lasts a few minutes. That may not be enough to want to do anything to stop the symptoms. If he has an episode that makes him go unconscious, then we may want to talk about it. Or, he may not have any symptoms at all.
So after the appointment, I got to talk to Chris about what to do if his heart ever starts beating really fast. I told him first of all, not to worry. Nothing bad would happen, and he didn't need to be scared. Then I told him secondly to tell me if it happens. He asked why, and I said I just need to know if it happens.
So that was that. We were there for 2 1/2 hours. If I'd had any idea it was going to take that long, I would've found a sitter for John and Ben. But for being there as long as we were, they did really well. Afterwards we went to Sonic for half-price slushies and I got frozen pizza for dinner that night. It was time to celebrate and take things easy! I was happy it was nothing serious and felt pretty confident we wouldn't see any symptoms.
Silly me.
The very next day, Chris says to me (all cheerful like) "It's happening!"
"What's happening?" I ask.
"My heart," he says.
Okay.
I feel his chest and yes, his heart is going VERY fast. Brian felt it too, and we exchanged a look. The good news is, Chris took to heart (no pun intended) my advice not to be scared. He wasn't scared one bit. In fact, he was very excited about something (see Thing Two below) and went on like it was nothing. I told him to tell me when it stopped and a minute or two later, he did.
Okay.
So now Brian and I are wondering. Has he had this before but just doesn't remember because he's so little? When his heart was going fast, I asked him if he ever felt that before and he said no. But what are the odds? I mean, the next day? I don't know what to think about that.
So later I looked up WPW Syndrome online. The doctor told me pretty much everything I read, except for what they do to treat it if symptoms are a problem. One option is medication, but that has to be taken 2-3 times a day for the rest of your life and (for kids especially) is not a good option.
The other option is a "minimally invasive" surgery, that involves putting a catheter through his veins, into his heart, and burning/destroying that extra electrical pathway. One or two days in the hospital.
Okay. I guess it could be worse, and if it comes to that, I guess... well, I'm not going to pretend I wouldn't be stressed about that and worried for Christopher, but I know it could be a whole lot worse. But I'm still going to hope his symptoms aren't bad enough to need any kind of procedure and that he outgrows this on his own.
So that's Thing One.
I'm way ready to move on to Thing Two!
Christopher finally has a new bed! He's been sleeping in a toddler bed this whole time and, yeah, it was getting a wee small for him. So here are pictures of Christopher on his new bed with his Wall-E bedding. :)
