The P wave in the ECG represents atrial depolarization, which results in atrial contraction.
p waves because they move rock back and forth which squeezes and strecthes the rock as they travel through. S waves shear rock side to side as they travel through the rock. know the defonitions of all waves. Primary or P waves are push and pull waves. They are also called longitudinal waves. These waves resemble sound waves, since both are compression-dilatation or compression rarefaction waves. Secondary, S or Shear Waves are also called transverse wave.
