Activity Chart
The activity chart on the programmer is divided into three ranges:
"MAR" (maximum activity rate), "Activity", and "No Activity." The activity
range indicates the time in which the sensor was active, but not with
the maximum sensor rate. All values are expressed as percentages.
Sensing Statistics
P-Wave Trend
This is where the course of sensitivity in the atrium is displayed. The P-
wave trend is displayed in the form of a line chart. The P-wave trend is
a rolling trend and records values in the range of 0.0 to 7.5 mV. The P-
wave trend can be:
— A long-term trend with a recording duration of 180 days
— A short-term trend with a recording duration of 33 hours
The long-term trend can be displayed only after recording has been
running for 3 days.
R-Wave Trend
This is where the sensitivity course in the ventricle is displayed. The R-
wave trend is displayed in the form of a line chart. The R-wave trend is
a rolling trend and records values in the range of 0.0 to 15 mV.
The R-wave trend can be:
— A long-term trend with a recording duration of 180 days
— A short-term trend with a recording duration of 33 hours
The long-term trend can be displayed only after recording has been
running for 3 days.
