Distinguish between P-wave and T-wave.

Solution:
  P-wave T-wave
 1In an electrocardiogram (ECG), the P-wave indicates the activation of the SA node. In an electrocardiogram (ECG), the T-wave represents ventricular relaxation. 
 2 During this phase, the impulse of contraction is generated by the SA node, causing atrial depolarization.  During this phase, the ventricles relax and return to their normal state.
 3 It is of atrial origin.
 It is of ventricular origin.
