Definitions:

ECG

Electrocardiogram, a test that measures the electrical activity of the heart to detect cardiac abnormalities.

QRS Complex

A series of waves on an electrocardiogram (ECG) representing the electrical impulses that trigger ventricular contraction during the heart's cycle.

S-T Segment

The portion of the electrocardiogram (ECG) tracing between the end of the S wave and the start of the T wave, representing the interval between ventricular depolarization and repolarization when the ventricles are electrically neutral.

Q-T Interval

A measure of the time between the start of the Q wave and the end of the T wave in the heart's electrical cycle, representing the period from the start of ventricular depolarization to the end of ventricular repolarization.
