The diagram given here is the standard ECG of a normal person. The P - wave represents the
contraction of both the atria
initiation of the ventricular contraction
beginning of the systole
end of systole
A.
contraction of both the atria
In ECG, P wave represents the depolarisation of atria, which leads to the contraction of both atria. T wave represents the return of ventricles from excited to normal state. The QRS complex represents the depolarisation of the ventricles, which initiates ventricular contraction. The contraction starts shortly after Q and marks the beginning of systole.
