S wave heart
SpletIn infants with heart rates in the range 100–150 beats/min one would expect the PR interval to be within the range 80–110 ms extending in occasional individuals to 150 ms. In teenagers with slower heart rates the upper limit of normal would be around 180 ms.

The QRS width is useful in determining the origin of each QRS complex (e.g. sinus, atrial, junctional or ventricular). Narrow complexes (QRS < 100 ms) are supraventricular in origin.

Splet26. jul. 2024 · Definition. A P wave on an electrocardiogram represents a phase of electrical activity that causes the atria of the heart to contract. The P wave is a summation wave – electrical activity that comes from successive signaling from multiple points, causing wave-like contractions. These multiple points contain pacemaker cells that generate ... Splet23. jul. 2024 · If the R and S waves are of equal size it means depolarisation is travelling at exactly 90° to that lead.
