Body Hacking: Thoughts Regarding My Magnet Implant
Body modification? Pacemaker here.<p>Every six months I have to go in for a tuneup, a wireless data dump & service testing. Having having one's heart slowed to sub-40bpm via a few taps on a screen is...odd. Printed report tells assorted stories of daily activity periods, odd events, heart rate hitting programmed thresholds, etc. There have been some confluence of proximity & programming causing twitching under some circumstances (couldn't sleep on my left side for a year due to a lead pressing on & convulsing diaphragm) which were fixed completely thru software settings. Have a minimum threshold programmed in, and if it's set too high (say, 60bpm) and I relax deeply can feel it kicking in with "go faster!"<p>Proved quite useful a couple weeks back. Suffered a random onset of aortic flutter (can happen to anyone, just sorta happens), where a natural short-circuit in the beat-signal nerves sent the heart rate up to 349bpm (neatly documented on the printed data dump). For most people, this means a very scary and tense race to the emergency room, with AED paddles & drugs to bring it down until the problem can be surgically eliminated. My pacemaker hit the brakes at 150bpm, leaving me functional to wander in to the ER at my convenience; there, a tech was brought in to set up a more aggressive flutter-control program (70-100bpm more aware of actual physical needs). That kept things manageable until the drive-thru heart surgery to fix the problem (1 hour to send a probe up a vein to find & burn out the short, 3 hours rest, then discharged). Wasn't what the pacer was installed to handle (ventricular resynchronization), but the "while we're installing this, let's add a wire and program in some other someday-useful stuff" has indeed proven useful.<p>Other body modification is a mechanical heart valve. I tick. I've been confused with clocks.<p>Yes, MRIs are completely out of the question now. Work near a small one and get nervous walking by the door.<p>OK, so these weren't exactly voluntary. Choice aside, being a cyborg does make for interesting experiences & conversations.<p>ETA: BTW, not looking forward to replacing the battery. At least the device has been saying the battery will last another four years - for the last four years.
