ECG Flashcards
1
Q
Show the summed electrical activity generated by all the cells of the heart
Not the same as an action potential
A
Electrocardiogram (ECG)
2
Q
Waves of the ECG
A
P wave
QRS complex
T wave
3
Q
P wave
A
depolarization of the atria
4
Q
QRS complex
A
wave of ventricular depolarization
Atrial repolarization is part of QRS
5
Q
T wave
A
repolarization of the ventricle
6
Q
Electrical events in the heart P, QRS, T
A
- P-wave (atrial depolarization)
- P-Q or P-R segment (conduction through AV node and AV node bundle)
3.Q wave - R-Wave- atrial repolarization
- S-wave
- ST segment
- T wave- ventricular repolarization
7
Q
The Heart Contracts and Relaxes during a
A
cardiac cycle
8
Q
cardiac muscle relaxes
A
diastole
9
Q
cardiac muscle contracts
A
Systole
