Woke up yesterday morning with no real plans except relaxing (the day before was something of an ordeal) and working with my physiotherapist. For a while, that was pretty much the case; I spoke with various visiting members of the team (showing off my ever-leaner right leg and complaining about my new chest pains), watched Gatchaman episodes, burned a CD to get through the boredom of an upcoming MRI, things like that.

Around noon things got a little too exciting. Several nurses had been trying to clear out a blockage in my feeding tube, with the fear that the visible blockage hid stuff farther up that might be far harder to remove, possibly necessitating the tube's removal and reinsertion. I felt a familiar sensation in my chest, on top of the various pains that made it hard to speak.

"Katie? Could you... check... my heart rate?"

Many of the nurses here check pulses the old-fashioned way, by holding your wrist. When she realized how fast my pulse was going, she tried to use one of the machines—only it couldn't read pulses that fast, either. Eventually they were able to get a reading of about 220, and I found myself explaining my history of tachycardia again.

By now a good deal of time had passed, and my heart wasn't slowing down. Katie told me they were going to call the RACE (Rapid Assessment of Critical Events) team.

Soon, my transplant physician showed up, and gave me a once-over physical exam, and asked a few more questions. Just then, my not terribly large room just filled with people and equipment. An EKG, a heart monitor and a blood pressure machine were hooked up to me to provide continuous testing before, during and after treatment. I was a complete mess of wires and tubes.

Once everything was ready, I was told what the present course of treatment was. They were going to inject me with adenosine and flush the line over about six seconds, which would get the complete dose into me in moments. What it would do was, essentially, stop my heart for a few seconds; when it restarted, the part of my cardiovascular system that regulates things would restart it at its regular rate.

"Until your heart restarts, you'll feel pretty awful," said Tom, the RACE doctor who would be doing this to me with a smile. At the same moment, I was asking, "What will this feel like?"

"There'll be a crushing sensation on your chest for about 3-5 seconds. If it hasn't restarted by then, you'll pass out until it does. It usually isn't more than 10 seconds."

What could I say? I had long passed the point where this was a danger to me. A distal (lower) port was used on one of the lines, and Tom went to town. Almost instantly I had trouble breathing, as invisible rhinos sat on my chest. I knew I wouldn't last much longer, when suddenly I felt my heart beating again (oddly, I'd never felt it not beating—but apparently it had).

Everyone's happiness was short-lived when someone noticed the truth: my heart rate had returned at the same rate as before!

Tom went off to confer with some other team members, leaving those of us in the room to talk amongst ourselves, organize things a bit, and make small talk. While doing those things I also listened to/felt the strange polyrhythm of the various devices attached to me.

Tom came back and gave me the new plan of action, which was remarkably like the old plan of action—only preceded by beta blockers and possibly alpha blockers to reduce my heart rate before hitting me with the terrible stuff.

So I braced myself, and we started the process. I got the first injection of beta blockers, and there was a wait as everyone who could see the monitor (i.e. everyone except me) looked at it intently and compared it to whatever they needed to compare it to. Eventually I noticed that no one was mentioning the terrible stuff anymore. Tom turned to me and said, "Quick, think of the most relaxing thing ever!"

I turned to Katie and said, "Quick, pass me my PSP!", fired up David Sylvian's "The Healing Place" and closed my eyes. A few moments later, Tom declared, "We did it!" They'd dropped my heart rate to 108 using only beta and alpha blockers.

There was a lot of activity as people milled about, exchanging information and keeping an eye on things. Gradually people started to retreat, disconnecting me from this or that gadget.

And in a wink of an eye, it was over. Jocelyne returned, and as Katie watched she got the feeding tube blockage cleared. Problems solved (and thoroughly tired), I went to sleep.
