Definitions:

Depolarization

A reduction in the difference in electrical charge across a cell membrane, leading to activation of the cell.

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.
