Many of these things have many causes, so you need to work … Webb1 feb. 2024 · The P wave is a small semi-circular shape located right before the tall QRS complex. It represents the electrical activity of the atria ("atrial depolarization"), which are the two small chambers located at the top of the heart. The QRS complex is the tallest most visible aspect of the ECG trace.

WebbThe first positive wave is simply an “R-wave” (R). The second positive wave is called “R-prime wave” (R’). If a third positive wave occurs (rare) it is referred to as “R-bis wave” (R”). Any negative wave occurring after a positive wave is an S-wave. WebbNormal ECG Intervals P-R interval. The P-R interval is measured from the beginning of the P wave to the beginning of the QRS complex. The P-R interval represents the time for depolarization of the sinoatrial (SA ) node, the atria, and the AV node. The normal P-R duration is 3-5 small boxes or 0.12 – 0.20 seconds. QRS interval
