What does the P wave correspond to?
atrial depolarization, atrial systole
What does the QRS complex correspond to?
ventricular depolarization, ventricular systole
Why is atrial repolarization not seen?
obstructed by QRS complex
What does the T wave correspond to?
ventricular repolarization, ventricular diastole
What happens during PR interval?
time from atrial depolarization to ventricular depolarization, includes AV node delay
What happens during PR segment?
AV node delay, allows ventricles to finish filling
What happens during ST segment?
ventricles fully depolarized, corresponds to plateau phase
What happens during QT interval?
full ventricular cycle from ventricular systole and depolarization to ventricular diastole and repolarization
