My ECG

I meant to post this a while back. In one of our more interesting lab classes, we got to hook ourselves up to an ECG and print out our results. I forgot the details already but I'm not flatlining and I have a regular beat. :) Actually the spike is the QRS Complex (my ventricles depolarizing). the bump before that, is the PR Interval (atrial depolarization), and the bump after the spike, is the ST Interval (when ventricular depolarization has ended and before repolarization starts). And my brain is mush, so I can't really explain further.
