Solution

The correct option is A The complex QRS- is one complete pulse.
The QRS complex is a name for the combination of three of the graphical deflections seen on a typical electrocardiogram (ECG). It corresponds to the simultaneous depolarization of the right and left ventricles of the human heart and also represents the pulse.
So, the correct answer 'The complex QRS- is one complete pulse.'
