The name P wave can stand for either pressure wave (as it is formed from alternating compressions and rarefactions) or primary wave (as it has high velocity and is therefore the first wave to be recorded by a seismograph). The name S wave represents another seismic wave propagation mode, standing for secondary or shear wave.. …

WebbIt is an R-wave, followed by an S-wave, followed by another R-wave. In other words, an upward deflection, followed by a downward deflection, followed by another upward deflection. Voila! That’s it. When an ECG reader mentions it, though, he/she is referring to an rSR’ in leads V1 and/or V2.
