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.
In a normal ECG following waves are present:
1. P Wave : It represents Atrial Depolarisation
2. QRS Wave : It represents Ventricular Depolarisation
3. T Wave :It represents Ventricular Repolarisation.
In the ECG of a normal healthy individual Repolarisation of atria would not be seen.
