EKG Flashcards
1
Q
P-wave
A
Atrial depolarization
2
Q
PR Interval
A
- Conduction from SA node to AV node
- Normal = .12 - .20 seconds (3 to 5 small boxes)
3
Q
QRS Complex
A
- Ventricular depolarization + atrial repolarization
- Normal = .06 - .10 seconds (1.5-2.5 small boxes)
4
Q
QT Interval
A
- Time for both ventricular depolarization + repolarization
- Normal = .20 - .40 seconds depending on HR (5 to 10 small boxes)
5
Q
ST segment
A
Isoelectric period following QRS
6
Q
T-wave
A
Ventricular repolarization
