Okay, So you've sat in class for a few lectures, looked at an ECG or two in a couple different labs, read through the primer, seven textbooks, and one clinical help book.  Now it's time to put that knowledge to the test.  Several real ECG's are below - follow the directions above each picture to check your ability to identify the major features of a normal ECG. 

1.    Click on the P-waves in this figure (note:   be fairly precise about where you point, otherwise the computer might not catch that your answer is right).

2.  Click on the T-waves in the following ECG:

3.    Just when you had that ECG down pat, we're moving to a different strip now!  Identify the Q waves on this ECG.
