, Jones Advanced ECG Exam Review
1. P wave depolarization of the atria
2. QRS Complex ventricular depolarization and atrial
repolarization
3. T wave ventricular repolarization
4. PR Interval delay of AV node to allow filling of ventricles
5. QT Interval ventricular depolarization and repolarization
6. ST Segment time during which ventricles are contracting and
empty-
ing
7. Net dipole determined by magnitude of depol. (# of cells) &
orienta-
tion of dipoles (same direction = stronger)
8. Mean electrical the average direction of the wave of
axis depolarization
--> largest dipole during R wave
9. Left axis deviation depolarization shifted to the left ventricle -->
from LVH,
R MI
10.Right axis depolarization shifted to the right ventricle -->
devia- tion RVH, L MI
11. 12 lead ECG An ECG that uses 12 leads attached to the
patient's skin;
these include the limb leads and chest leads
