Example: Ventricular Form(s)
Across the screen are displayed the corresponding forms. Forms are labelled by beat classification
and also highlighted in the corresponding color:
Ventricular = V = Red
Normal = N = White
AF = N = Yellow
Supraventricular = SV = Green
Artifact = I = Grey
Removed = R = Grey
The form number is at the top of each Form, with the number of beats in form shown in the
bottom right of it’s box. A yellow triangle indicates the trigger point on the morphology display.
Click on a form and the beats in form are shown the lower half of the display.
Note:
When there are more forms/beats than can be displayed on screen, a vertical scrollbar is
displayed.
The operator can select either the form, which includes all the beats in the form, or the form
and then specific beats in the form. The selection is displayed on the top left control panel. Use
‘Shift+select’ to select groups of forms / beats or ‘Ctrl+select’ to select multiple non-adjacent.
Click the Clear button to clear the selection, or click on a different morphology.
Any ECG channels that were NOT used when shape matching beats to create the Morphologies are
displayed in black, Matched channels are displayed in their normal colors.
Re-classify Forms / Beats in Forms: Select the form or beat. Either select the new classification
from the left control panel or right click and select it from the menu. Where you have a beat
selected but wish to reclassify all beats in form you should ‘clear’ the selection first and then
reclassify just the form.
Merge Forms: Use the mouse and the Shift / Ctrl key to select forms and then select the Merge
icon on the left control panel to merge the forms together or select and drag individual forms
onto others to merge.
Note:
For Normal Forms it is recommended that these are merged into 1 form for more efficient
ECG Scanning
The operator can also right click on a form a select a dominant channel to merge beats together
against: ‘Select Similar forms using first channel’. This will highlight all forms with a similar shape
in only that channel.
Split Forms: Use this to create more Forms where the diversity within a form is too great or the
wrong beats have been included.
Create New:
Select a beat in Form and the Create New icon from the left menu to create a new
form.
Toggle baseline filter: This will re-set all the beats in form to sit on the same baseline making for
easier comparison of shapes.
Overlay:
Select a Form and then Overlay from the left control panel. This will overlay every beat in
form. Use this to quickly identify forms with beats incorrectly included.
