ECGs Flashcards
1
Q
What does ECG stand for?
A
Electrocardiogram
2
Q
What does the P wave of a ECG represent?
A
Atrial depolarisation
3
Q
What does the PR interval represent on an ECG?
A
The time taken for the depolarisation wave to move between the atria and ventricles.
4
Q
What does the QRS complex of an ECG represent?
A
Depolarisation of the ventricles
5
Q
What does the ST segment of an ECG represent?
A
The time between the depolarisation and repolarisation of the ventricles. I.e.the contraction
6
Q
What does the T wave of an ECG represent?
A
The repolarisation of the ventricles
7
Q
How is a first degree AV block represented on an ECG?
A
