The R and S waves on the EKG show how the heart is contracting and whether or not there is anything wrong with the beating of the heart or the structure of the heart.
The only EKG waves are P, Q, R, S, T, and U (abnormal). Actually, there are other waves. The "A" , "C", and "V" waves are found on the EKG during atrial filling or DIASTOLE. The "A" wave is the result of the atrial contraction and can be found in the PR interval. This "A" wave is a type of fluid volume indicator, the more the atrium fill, the higher this wave will be.
r wave, a part of the q-r-s complex.

S waves are generally more damaging than P waves because they have a greater amplitude and cause more intense shaking. However, P waves travel faster than S waves, which means that people farther from the earthquake's epicenter may feel the P waves before the stronger S waves arrive.

An EKG, or electrokardiogram (the German spelling is where the abbreviation comes from), measures the electrical activity of the heart. The waves are called P, Q, R, S, T, and occasionally U (an abnormality). The "spike" is called the QRS Complex.

seismic waves actually the correct answer is S waves. trust me if you put seismic waves it will be wrong
