Intervals and segments. PR Interval: From the start of the P wave to the start of the QRS complex. PR Segment: From the end of the P wave to the start of the QRS complex. J Point: The junction between the QRS complex and the ST segment. QT Interval: From the start of the QRS complex to the end of the T wave.

The PR Interval indicates AV conduction time. In this step you should measure the interval from where the P wave begins until the beginning of the QRS complex

The PR segment is the flat line between the end of the P-wave and the start of the QRS complex. The PR segment reflects the time delay between atrial and ventricular activation. The PR segment also serves as the baseline (reference line or isoelectric line) of the ECG curve. PR segment = depolarization of the AV node. I.e. When current is passing through the AV node. It’s a flat line because the wave is not strong enough to be recorded on the voltmeter.

Note that the length of the ST segment is rarely used in clinical electrocardiogrpahy because the end of the QRS complex may not always be easy to define. The morphology of the ST segment (shape, and deviation from the isoelectric baseline that is usually defined as the amplitude of the PR segment) is important.

A normal PR interval measures 0.12-0.20 seconds which is 3 to 5 small boxes on the EKG strip. When you measure a PR interval, you start measuring at the BEGINNING of the p-wave until the BEGINNING of the QRS complex.

2021-03-20 · PR segment is the isoelectric segment between the end of the P wave and the start of the QRS complex. It is included in the PR interval (read difference between segments and intervals). Causes of PR Segment Depression:

TP interval is the isoelectric line. Although the PR interval may meet the isoelectric line as well, and if it is visible is what you should probably measure ST elevation against. If the P wave is elongated or PR segment is shortened for some reason however you may not see it reach the isoelectric line.
