The bars of the histogram are standardized to a rate class 
width of 10 ppm to avoid distortion of the rate distribution.

Statistics 
2.21.1 Tachy Episode Trend 
The Tachy Episode trend can only be selected when Mode 
Switching has been programmed ON and for events that occur 
at less than 1 minute intervals are combined in the tachy episode 
and stored.  
In the tachy episode trend, each tachycardic mode switching 
episode is recorded in the statistics table with its initial date and 
time as well as its duration.  This documents both the frequency 
and length of the tachycardic periods which can be evaluated in 
the follow-up. 
Mode Switch Counter – A counter reports the number of mode 
switches that occurred since the last follow-up visit. 
Mode Switch Trend (Tachy Episode Protocol) - The trend 
records up to 64 atrial tachycardia episodes that result in a mode 
switch.  The trends are available as a rolling trend and therefore 
contain information about the most recent events.  The atrial 
tachycardia episodes are displayed graphically as a function of 
time on the programmer screen.

When the elective replacement indication (ERI) has been 
attained, the contents of the tachy episode trends as well as 
all memory contents are “frozen” and further recording is 
stopped. 
2.21.2 AF Classification 
To adequately record atrial fibrillation (AF) and reduce the 
number of times the recording is turned ON and OFF, a lower 
and upper AF detection rate can be set.  Both the lower sensing 
rate as well as well as the upper resolution rate is 
programmable: (100… (10)…300…… (2)…400 ppm).
