T/F The horizontal axis on the EKG strip True
represents time and is measured in
fractions of a second.

T/F The vertical axis of the EKG strip True
measures amplitude, or voltage.

Small box 0.04 seconds

5 small boxes 0.2 seconds

5 large boxes 1 second

The P wave represents depolarization, or contraction, of the atria

The QRS complex represents depolarization, or contraction, of the ventricles

The T wave represents Repolarization of ventricles
