In ECG deflection waves, ventricular systole occurs during
Open in App
Solution
The correct option is C QRS
ECG (Electrocardiogram) represents the electric current that moves through the heart during a heart beat. An ECG shows five consecutive waves i.e. P, Q, R, S and T.- P wave represents the depolarisation of atria when both the atria contract.
- QRS complex represents depolarisation of ventricles when ventricular systole i.e. contraction of ventricles occur.
- T wave represents ventricular repolarisation when ventricles return from excited state to normal state.
So, the correct answer is 'QRS'.
