Vector view (optional)
The Vector view is only available if the
vectorcardiogram option is enabled. It displays
the results of an ECG in a vectorcardiogram.
The left hand pane displays the reconstructed
orthogonal x, y and z leads. The right hand side
of the Vector view is divided into three windows.
Window 1 displays the following loops:
F: complete frontal loop
H: complete horizontal loop
R: complete right sagittal loop
Window 2 displays the following loops:
Ft: frontal plane of the T wave
Ht: horizontal plane of the T wave
Rt: right sagittal plane of the T wave
Window 3 displays the following loops:
Fp: frontal plane of the P wave
Hp: Horizontal plane of the P wave
Rp: Right sagittal plane of the P wave
R-R view (optional)
R-R is the interval between two subsequent
QRS complexes. The R-R view gives an
overview of the heart rate variability. This view
lists the number of intervals, the minimum,
maximum and average number, and the
standard deviation.
The Trend graph displays the duration
of the subsequent intervals. The x-axis
lists the interval numbers. The y-axis
displays the duration.
The Histogram graph displays the
distribution of the intervals. The x-axis
lists the duration (in ms, divided into
bins of 8ms). The y-axis lists the
number of intervals that falls in a
particular bin.
