<P> The QRS complex is a name for the combination of three of the graphical deflections seen on a typical electrocardiogram ( EKG or ECG ) . It is usually the central and most visually obvious part of the tracing , in other words , it 's the main spike seen on an ECG line . It corresponds to the depolarization of the right and left ventricles of the human heart and contraction of the large ventricular muscles . </P>
