Meanwhile in Canada...
...They perform a "Stress Test" (which isn't, as you may suppose, renegotiating NAFTA with a semi-sentient simeon), but is being connected to an EKG and walking on a treadmill until one's heart rate reaches 140 bpm. Takes maybe 30 minutes. Probably costs $150 all in.
Apparently, there's also a connection to Chaos Math in terms of how the heart regulates the beating of the various chambers. IIRC, it was mentioned in James Gleick's book "Chaos - making a new science".
