8.2.14 Vector Cardiogram
Vector cardiograms and measurements can be displayed when leads Frank, or
standard + X, Y, Z have been taken on the original recording.
With the vector option, X, Y, Z leads can be calculated to enable vector cardiograms
to be generated from a standard 12 lead recording.
Select Vector ECG .
A vector cardiogram traces the direction and magnitude of the heart's
electrical
activity during a cardiac cycle. It is produced from the three orthogonal leads X, Y, Z.
The size (magnitude) and the direction of a vector are indicated by three spatial
coordinates (X, Y and Z). The shape, the direction of the rotation, the orientation and
the speed of rotation of the individual loops are the predominant factors for the
analysis of the vector cardiogram. Vector loops are represented spatially and
projected on the following three planes:
• Horizontal plane (X, Z)
• Frontal plane (X, Y)
• Sagittal plane (Z, Y)
The P wave, QRS and T loops can be
displayed in any combination
