ECGs Flashcards
1
Q
P wave
A
Atrial depolarisation causing contraction of the atria
2
Q
PR Interval
A
The wave of depolarisation reaches the Atrio-Ventricular Node. This depolarises and conducts but slows the wave
3
Q
QRS Complex
A
Ventricular depolarization & ventricular contraction.
AVN conducts the depolarization to the bundle of his and conducting tissue, causing contraction of both ventricles.
4
Q
T Wave
A
Ventricular repolarisation
The ventricles repolarise, returning to the resting
potentia
