CCT Exam Practice - Performing Resting ECG

1. proper skin preparation for ECG - clip excess hair from application
sites to ensure proper skin contact
with the electrode (as needed)
- cleanse site with mild soap and
water (avoid using alcohol)
- if the patient is wearing lotion, it
should be washed off prior to the
placement of electrodes
- dry skin completely before apply-
ing electrodes
- light exfoliation of the skin site
the quality of the signal received
from the electrodes is a direct re-
sult of skin preparation and lead
placement.
2. approach the patient from the __________ when left side
performing an ECG
3. calibration of ECG machine 10 mm height and recorded at 25
mm/sec
4. limb leads RA, LA, RL, LL
5. bipolar leads are three leads with negative and pos-
itive poles
lead I, lead II, lead III
6. lead I right arm (-) to left arm (+)
7. lead II right arm (-) to left leg (+)

8. lead III left arm (-) to left leg (+)
9. Einthoven's triangle the triangle around the heart
formed by the bipolar limb leads
10. Einthoven's law lead I + lead III = lead II; lead II
should have the tallest QRS of the
bipolar leads
11. augmented leads unipolar limb leads identified as
aVR, aVL, and aVF
all positive
12. aVR positive pole on right arm
13. aVL positive pole on left arm
14. aVF positive pole on left foot
15. chest leads (precordial leads) V1, V2, V3, V4, V5, V6
16. V1 4th intercostal space to the right of
the sternum
17. V2 4th intercostal space to the left of
the sternum
18. V3 between V2 and V4
19. V4 5th intercostal space, left midclav-
icular line
20. V5 horizontal to V4 at left anterior ax-
illary line
