\({\rm{P}}\)' wave of ECG occurs just before the
1 onset of ventricular contraction.
2 end of atrial contraction.
3 beginning of atrial contraction.
4 none of the above.
Explanation:
The P-wave indicates atrial depolarization, which causes atrial systole. During this wave, the impulse of contraction is generated by the SA node.

ECG depicts the depolarisation and repolarisation processes during the cardiac cycle. In the ECG of a normal healthy individual one of the following waves is not represented.
1 Depolarisation of atria
2 Repolarisation of atria
3 Depolarisation of ventricles
4 Repolarisation of ventricles
Explanation:
\(\mathrm{P}\) wave shows depolarisation of atria. QRS complex shows depolarisation of ventricles \(T\) wave shows repolarisation of ventricles.

The given figure represents diagrammatic presentation of an ECG. Each peak in the ECG is identified with a letter from \(\mathrm{P}\) to \(\mathrm{T}\) that corresponds to a specific electrical activity of the heart.
1 QRS - Depolarization of the ventricles
2 R wave - Marks the end of the systole.
3 P-Electrical excitation (or depolarization) of the atria
4 T wave - Return of the ventricles from excited to normal state (repolarization).
