Short rr interval

Splet22. nov. 2024 · The R-R interval is the distance between two consecutive R waves. In sinus rhythm, this interval should be constant. The duration of the R-R interval depends on the heart rate. It is measured from the … Splet04. feb. 2024 · The PR interval is the time from the onset of the P wave to the start of the QRS complex. It reflects conduction through the AV node. The normal PR interval is between 120 – 200 ms (0.12-0.20s) in duration (three to five small squares). If the PR interval is > 200 ms, first degree heart block is said to be present.
