ECG Basics Flashcards
1
Q
What does the P wave correspond to?
A
Atrial depolarisation
2
Q
What does the PR interval correspond to?
A
AV nodal delay
3
Q
How long should the PR interval be, and how can you assess this easily?
A
0.12 - 0.2 seconds - it should not be longer than one large box
4
Q
What does the QRS complex correspond to?
A
Ventricular depolarisation
5
Q
How long should the QRS complex last, and how can you assess this easily?
A
< 0.1 seconds - it should not be wider than half of one large box
6
Q
What does the ST segment correspond to?
A
Ventricular contraction (systole)
7
Q
What does the QT interval correspond to?
A
Depolarisation and repolarisation of the ventricles
8
Q
What does the T wave correspond to?
A
Ventricular repolarisation
9
Q
What does the TP interval correspond to?
A
Ventricular relaxation (diastole)
