Answer

This represents the waves recognized during the heart beat noticed during ECG. The following is the sequence :

1.P wave -It is the first wave noticed and is associated with right and left atrial depolarization atrial contraction.

2.Atrial contraction(systole).

3.QRS complex It is the second wave that is seen and is associated with the right and left ventricular depolarization.

4.ventricular contraction.

5. T wave- represents current of rapid phase 3 where ventricular re polarization occurs.

6.ventricular relaxation(diastole)
