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.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). This would be described as an RSR' pattern.
where QTcB is the QT interval corrected for heart rate, and RR is the interval from the onset of one QRS complex to the onset of the next QRS complex, measured in seconds, often derived from the heart rate (HR) as 60/HR (here QT is measured in milliseconds).
