ECG Flashcards
1
Q
What does the PR interval correspond to and what is the normal duration?
A
Atrial depolarization
0.12-0.2 sec.
2
Q
What does the QRS complex correspond to and what is the normal duration?
A
Ventricular depolarization
0.08 sec
3
Q
What does the QT interval correspond to and what is the normal duration?
A
The time the ventricle is spent depolarized
The duration depends on heart rate - 0.42 sec at 60bpm
4
Q

A
Count the amount of QRS complex’s there are in 30 squares X 100.
5
