Solution:
In ECG, P-wave indicates impulse of contraction generated by SA-node and it spreads in atria causing atrial depolarisation. T-wave is the most constant and conspicuous wave having the tallest amplitude. It is the first positive deflection during ventricular depolarisation. S-wave is the next downward deflection constant but often inconspicuous. T-wave is repolarisation wave of ventricular relaxation.
