Assertion :
ECG is a record of electrical activity of the heart that shows certain waves called PQRS and T waves.
Reason :
It gives important information concerning the spread of excitation to the different parts of the heart and helps in diagnosis of heart disorders.

Choose the correct statement among the following:
I. Atrio-ventricular node is the pacemaker that generates action potential and initiates the atrial systole.
II. During each cardiac cycle, the 'lubb' sound is due to the closure of semilunar valves.
III. Stroke volume in each cardiac cycle is approximately \(170 \mathrm{ml}\) of blood.
IV. QRS complex in an ECG indicates depolarization of ventricles.
