Hence it is recommended that you ensure that stable atrial sensing
exists prior to the activation of the VES analysis. If the atrial lead is
bipolar, bipolar sensing should be considered.
The event counters of the VES classification are subdivided into three
percentage classes:
— 0 - 25%
— 25 - 50%
—

50%
In addition, individual VES, couplets, triplets, runs, tachycardias and
the maximum number of VES per hour are displayed.
VES Versus Ventricular Rate
The VES vs. ventricular rate is likewise displayed in a histogram with
16 equidistant classes of < 40 to >179 ppm. The graphical display
shows the percentages of the individual classes in the form of a bar
chart and the total number of events.
VES Coupling Interval
The VES coupling interval documents the time difference between a
regular ventricular event and subsequent VES of 0 to 500 ms duration.
This display corresponds to the three event counters of prematurity at
0-25%, 25-50% and > 50%. The graphical display shows the
percentage value of the individual classes in the form of a bar chart
and the total number of events.
