Question 1

Show the summed electrical activity generated by all the cells of the heart
Not the same as an action potential

Answer 1

Electrocardiogram (ECG)

Question 2

Waves of the ECG

Answer 2

P wave
QRS complex
T wave

Question 3

P wave

Answer 3

depolarization of the atria

Question 4

QRS complex

Answer 4

wave of ventricular depolarization
Atrial repolarization is part of QRS
