When measuring PR interval, there is something you need to know beforehand: Normal PR interval between 0.12-0.20 seconds equals 3 to 5 small squares on the EKG strip; You always start measuring first, going from the beginning of the P-wave all the way until the beginning of the QRS complex; Steps to …
Web16 jul. 2024 · Here are some simple steps on how to measure the PR interval: Find the P-wave on the EKG strip. Determine where the PR interval is, and to do this you start measuring at the beginning of the p-wave until the beginning of the QRS complex. Count the SMALL boxes between there measurements. Remember each box represents 0.04 … WebCalculating the interval is simple and only involves counting the number of small boxes from left to right and then multiplying this by 0.04 seconds. For example, suppose that the PR interval is measured as four small boxes across. When we multiply four by 0.04 seconds, we get 0.16 seconds.
