Cardiovascular system - Cardiac conduction system Flashcards
1
Q
What is the Primary wave on the ECG?
A
Atrial systole - Depolarisation and contraction of the atrial muscles
2
Q
What is the period after the primary wave on the ECG?
A
PR segment - a flatline after the primary wave, where the signal enters the AV node
3
Q
What is the Q wave on the ECG?
A
The beginning of ventricular systole, and atrial
4
Q
What is the R wave on the ECG?
A
The stimulus passing trough the main portion of the ventricular walls
5
Q
What is the S wave on the ECG?
A
final depolarization of the ventricles
6
Q
What is the period after the QRS?
A
Ventricular diastole - The ventricular walls relax
7
Q
What is the T wave on an ECG?
A
the repolarization of the ventricles
