Moored Name Meaning Historically, surnames evolved as a way to sort people into groups - by occupation, place of origin, clan affiliation, patronage, parentage, adoption, and even physical characteristics (like red hair).
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.
QRS complexes found in a 6-second portion of the ECG tracing. â¢ The 300, 150, 100, 75, 60, 50 method involves locating an R wave. on a bold line on the ECG paper, then finding the next consecutive. R wave and using the 300, 150, 100, 75, 60, 50 values for. subsequent bold lines to determine the rate. â¢ To use the 1500 method count the number of small squares. between two consecutive R waves and divide 1500 by that number.
