I've been back to doing some exercise.
The four mile workouts at South Park have been pretty good. I walk for two miles and then run for about a mile and a half and then walk the last half mile or so. My heart rate pops up pretty fast to about 80% maximal, and I can keep it there for the run. For some reason, I can't seem to run any slower. Exercising at 80% repeatedly will result in over-training.
Since I'm doing 4 miles with no trouble, I thought the 3.5 mile walk on the Eliza Trail to see Floyd and go to Eides' Comic Book store on Friday would be fine. I'd have to take it easier, of course.
Walking at an easier pace is actually harder for me than walking at a brisk pace or running. Those PVCs are caused by something in my ventricle that gets impatient waiting for a heartbeat. If my heart rate is too slow, there's more of a chance that that something getting annoyed and firing off a beat early. Since it's not designed to fire off beats on it's own, the beat's not nearly as good as one that comes from the normal place.
So there I go on that walk, and I get hit by a "light grey out." My brain feels like it's not working at 100%, and there's this feeling of impending doom. I get a wash of anxiety all over me.
"I know what that is!" I think. "It's nothing to worry about: I can relax."
"My heart just isn't beating right."
Now, the phrase "It's nothing to worry about: I can relax" doesn't go too well in my brain with "My heart just isn't beating right."
There's an old paramedic joke about how to deal with emergencies. In an emergency, check to see if you have a pulse. If you do, then there's nothing for you to worry about. It sucks to be the person stretched out on the floor doing an "O" or "Q" (think of an open mouth, with or without tongue protruding), but you've got nothing to worry about.
Checking my pulse yields:
Beat…beat…beat…nothing…beat…beat…beat…nothing…beat…nothing…beat…beat…beat.
This is, quite literally, a new definition of "nothing to worry about." The doctors know what they're talking about. I've checked up on it, and the odds of me dropping over dead from this aren't much different than if I had a perfectly normal heartbeat. This is new information that has to compete with years of "We need to get lidocaine onboard before the patient makes us do the old "Pump and Blow." Make sure the defibrillator is handy, just in case."
I work hard to not think of Jim Fixx, the running guru who died of heart disease while running. I avoid remembering my friend who, just after seeing the cardiologist, went into cardiac arrest for 20 minutes and is still fighting to recover from the resulting brain damage. The stories of others who went to an E.R. for "rule out heart problem" and died after being released are not the best things to ponder right now.
The biological subroutines are beyond my control. When I go into the irregular heartbeat, the malfunction produces error messages designed to elicit fear. I don't think I can unlearn that reaction, and I'm not even sure I want to. The sudden surge of adrenaline from those glands over my kidneys picks my heart rate up a bit — making those irregular heartbeats go away.
So I started off on my walk, trying not to think about what my EKG must look like.
One mile into the walk, I feel like I've been punched in the solar plexus. Something's upset my stomach again. The cell phone's in my hand, just in case. Walk. Breathe. Walk. Breathe.
I notice I'm getting more of those irregular heartbeats. The absolute best I can hope for is that my stomach is irritating the heart and causing those PVCs. How I'm feeling right now would seem to confirm that.
Walking will help the stomach, help me lose weight, and help the heart.
So I do what the doctors tell me. I exercise as much as I can. I'm watching my diet and taking all those funky acid blockers. I can do this.
All I have to do is ignore the emotions that go along with it. All those hours of training for the marathons, where I did not want to put in my exercise time but made myself do it anyhow, where I felt like blowing off a day but didn't…now I'm seeing the real reason I did it.
Have I ever mentioned how much training for a marathon sucks? We're talking big time suckitude.
Y'know, it just hit me. I should sign up for a marathon. I mean, come on, if I have to put myself though this crap, at least I can get a T-shirt out of it. So, what should I aim for? Chicago? Florida? Rhode Island? Washington D.C.?
