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. It corresponds to the depolarization of the right and left ventricles of the human heart.In adults, it normally lasts 0.06â0.10 s; in children and during physical activity, it may be shorter. Typically an ECG has five deflections, arbitrarily named P to T waves.ny abnormality of conduction takes longer and causes widened QRS complexes. In bundle branch block, there can be an abnormal second upward deflection within the QRS complex, in this case such a second upward deflection is referred to as R' (pronounced R prime).
