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.
