Practice Time: Identify the wave!
|Created by Diane R. Karius, Ph.D.|
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.
4. Now, identify the S waves on the ECG strip (below):
