PR Interval: 0.12 - 0.20 sec ; QRS Duration: 0.06 - 0.10 sec ; QT Interval (QT c ≤ 0.40 sec) Bazett's Formula: QT c = (QT)/SqRoot RR (in seconds) Poor Man's Guide to upper limits of QT: For HR = 70 bpm, QT ≤ 0.40 sec; for every 10 bpm increase above 70 subtract 0.02 sec, and for every 10 bpm decrease below 70 add 0.02 sec. For example:

2021-03-20 · Related article: PR interval. The PR interval represents the atrial depolarization and physiological delay of the stimulus in the atrioventricular (AV) node. It is measured from the beginning of the P wave until the beginning of the Q or R wave. Its normal value is between 0.12 s and 0.20 s. Remember back in ECG basics we reviewed what the PR interval was? If something were to delay the conduction of the electrical impulse from the atria to the ventricles, you would see an increase in the PR interval. A normal PR interval should be 0.12 - 0.2 seconds long (3 - 5 small squares) Ambulatory ECG monitoring shows that at all ages some individuals with a normal resting PR interval will from time to time have periods when the PR interval becomes prolonged to >200 ms.

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.
