Final answer:
The QRS Complex is the part of the EKG that represents the depolarization of the ventricles and the contraction of the heart.
Step-by-step explanation:
The part of the EKG that is named QRS Complex.
The QRS complex represents the depolarization of the ventricles, which is the electrical activation that leads to the contraction of the ventricles and the pumping of blood to the lungs and body.
It is a large and distinct waveform on the EKG tracing, and its duration and shape can provide important information about the health and function of the heart.
