ECG Tracing: Between Waves and Intervals (Part 3)
A NewTech ECG Equipment Brand Review


Now we are on the third part of ECG Tracing: Between Waves and Intervals article series, we will now be discussing the next component of ECG tracing which is called PR/PQ interval.

PR/PQ interval In a Nutshell

The PR interval is measured from the beginning of the P wave to the beginning of the QRS complex. It is usually 120 to 200 ms long. On an ECG tracing, this corresponds to 3 to 5 small boxes. In case a Q wave was measured with a ECG the PR interval is also commonly named PQ interval instead.

• A PR interval of over 200 ms may indicate a first degree heart block.
• A short PR interval may indicate a pre-excitation syndrome via an accessory pathway that leads to early activation of the ventricles, such as seen in Wolff-Parkinson-White syndrome.
• A variable PR interval may indicate other types of heart block.
• PR segment depression may indicate atrial injury or pericarditis.
• Variable morphologies of P waves in a single ECG lead is suggestive of an ectopic pacemaker rhythm such as wandering pacemaker or multifocal atrial tachycardia.
