What is a segment in EKG?
Segment in EKG: EKG is same as ECG or electrocardiogram. ECG has a few waves and a few segments. The usual waves are P, QRS and T. The region between the P and QRS is known as PQ segment or more popularly as PR segment (as Q waves may not be seen always – QRS complex can consist of Q wave, R wave and S wave or varying combinations of these). The segment between the S wave (or the end of the QRS complex) and the T wave is known as the ST segment. TP segment is between the end of the T wave and the next P wave. TP segment is truly isoelectric (and hence the true baseline for all ECG measurements) while the other two segments may have deviations from the baseline.
