ECG wave components Flashcards
1
Q
P wave
A
atrial depolarization
2
Q
PQ interval
A
time for atrial kick to fill ventricles
3
Q
QRS wave
A
ventricular depolarization
, then
atrial repolarization
4
Q
S-T segments
A
time for emptying, enters the ventricles before relaxation/repolarization
5
Q
T
A
ventricular repolarization
6
Q
U wave
A
relaxation of Purkinje fibers - not common
