An Old Physiology Project — Operation Spinny Chair :D

I discovered this ancient report in my repository about three months ago– I’ve finally decided to put it up because it made my day reading the abstract again. This is definitely one of my prouder albeit sillier projects from the days of my undergrad.

Independent Research Project Acute centripetal acceleration is correlated with increased heart rate and R-wave amplitude

Matthew Boyle, Bryan Chung, Eddie Ma

Abstract

In the present study, we set out to discover the correlation between the exposure of acute centripetal acceleration in human subjects and cardiovascular function across the following three dimensions: Heart rate, R-wave amplitude and QRS interval. This was accomplished by measuring the above properties via Lead II Bipolar ECG trace, after having spun the subject at 0.8 revolutions per second in an office chair for successively, 30, 60 and 90 seconds. It was determined that heart rate showed strong positive correlation (n = 3, average increase between trials of increasing duration, 3.2 beats per minute, s = 1.8). R-wave amplitude showed positive correlation in all subjects up until and including the 60 second trial. There was no systemic correlation between duration of spin and the length of the QRS interval in any of the subjects. The heart is therefore an important effector in response to centripetal acceleration in the human model.

Key Words: electrocardiogram, QRS interval, centripetal force, R-wave amplitude, spinning office chair.

YES. This easily trumps the mathematical study on zombie propogation as my favorite esoteric paper.

You’re too kind Matthew 😛 — Incidentally, I’ll come bother you for the link to the zombie paper mentioned.
