Definitions:

S-T Segment

The part of an ECG between the S and T waves, representing the period when the ventricles of the heart are depolarized, which should be flat if the heart muscle is receiving adequate oxygen.

P Wave

The deflection in an electrocardiogram (ECG) that represents atrial depolarization,preceding the contraction of the atria.

Q-T Interval

A measurement on an electrocardiogram (ECG) that represents the time between the start of the Q wave and the end of the T wave, indicative of the duration of ventricular depolarization and repolarization.

Ventricular Contraction

The phase of the cardiac cycle in which the ventricles contract, pumping blood out of the heart into the systemic and pulmonary circulations.
