A Beginners Guide to Normal Heart Function, Sinus Rhythm & Common Cardiac Arrhythmias. The S Wave. You will also have seen a small negative wave following the large R wave. This is known as an S wave and represents depolarisation in the Purkinje fibres.

Any negative wave occurring after a positive wave is an S-wave. Large waves are referred to by their capital letters (Q, R, S), and small waves are referred to by their lower-case letters (q, r, s). Figure 5 shows examples of naming of the QRS-complex.
In seismology and other areas involving elastic waves, S waves, secondary waves, or shear waves (sometimes called elastic S waves) are a type of elastic wave and are one of the two main types of elastic body waves, so named because they move through the body of an object, unlike surface waves.
S Wave. The S wave is the first downward deflection of the QRS complex that occurs after the R wave. However, a S wave may not be present in all ECG leads in a given patient. In...
Definition. An s-wave, or secondary wave, is a type of seismic wave that moves through the Earth's interior and is characterized by its shear motion, which causes particles to move perpendicular to the direction of wave travel.
S-waves, or secondary waves, are a type of seismic wave that move through the Earth during an earthquake. They are characterized by their transverse motion, which means they move the ground perpendicular to the direction of wave propagation, and are only able to travel through solid materials, making them crucial for understanding Earth's ...
8 Οκτ 2024 · The ST segment is the flat, isoelectric section of the ECG between the end of the S wave (the J point) and the beginning of the T wave. The ST Segment represents the interval between ventricular depolarization and repolarization. The most important cause of ST segment abnormality (elevation or depression) is myocardial ischaemia or infarction.
