Formats
The VCG formats correspond to the layout of the frontal, horizontal,
and sagittal QRS loops and the angular scales used for the axes.
There are four different VCG report formats: VCGl, VCG2, VCG3,
and VCG4. Each report format shows a different relative position of
QRS loops within the loop representation area and uses a different
angular scale.

Sagittal Projection Angular Scale
Right sagittal
Left sagittal
0' to 360'
0' to 360'
Right sagittal -180' to $180'
Left sagit tal -180° to +180°
'Format conforms to the recommendations of the AHA.
The horizontal plane is always viewed from the head rather than the
foot and the frontal plane is viewed from the chest and not the back.
But, the sagittal plane is not standardized and can be viewed from
either the left or the right side. Therefore, we support both the left
and right sagittal projections in each of the two types of reports.
