As a medical professional with expertise in cardiology, I often deal with electrocardiograms (ECGs) which are crucial tools for diagnosing heart conditions. One of the key measurements on an ECG is the PR interval, which represents the time between the start of the P wave and the beginning of the QRS complex. This interval is a reflection of the time it takes for the electrical impulse to be transmitted from the atria to the ventricles, preparing them for contraction.
Normal PR Interval: The normal PR interval on an ECG is typically between 0.12 to 0.20 seconds (or 120 to 200 milliseconds). This value can vary slightly based on age and other factors such as heart rate. A PR interval that falls outside of this range may indicate a conduction delay, such as first-degree atrioventricular (AV) block, or other heart conditions that require further evaluation by a healthcare provider.

The first measurement is known as the "P-R interval" and is measured from the beginning of the upslope of the P wave to the beginning of the QRS wave. This measurement should be 0.12-0.20 seconds, or 3-5 small squares in duration.
