ECG waves Flashcards
1
Q
Recording of currents from cardiac conduction on skin
A
electrocardiogram (EKG or ECG)
2
Q
composite record of action potentials produced by all the heart muscle fibers during each heartbeat.
A
ECG
3
Q
- represents atrial depolarization
• Contraction begins right after peak
• Repolarization is masked in QRS
A
P wave
4
Q
- rapid ventricular depolarization
• Contraction of ventricle
A
QRS complex
5
Q
- ventricular repolarization
• Just after ventricles relax
A
T-wave
6
Q
atrial depolarization
A
P-wave
7
Q
onset of ventricular depolarization
A
QRS complex
8
Q
ventricular repolarization
A
T wave
