How High Rate Episodes Are Defined
For the purposes of this diagnostic, a “high rate episode” begins when a
specified number of sequential heart beats exceeds a specified rate. The
episode ends when a specified number of sequential heartbeats occur below
the specified rate. The table that follows describes the programmable
parameters that define a high rate episode.
Programmable Parameters for High Rate Episode Detection
Parameter Range Meaning
Detection Rate 80 to 400 ppm The minimum rate above which the atrial or
ventricular rate is declared a high rate
episode.
Detection 2 to 200 events The number of sequential events above the
Number Detection Rate required for a high rate
episode.
Termination 2 to 20 events The number of sequential events below the
Number Detection Rate required to end a high rate
episode.
Programmable Data Collection Options
The following programmable options control how episode data are
collected:
Programmable Options for High Rate Episode Data Collection
Parameter Values Meaning
Type Atrial or Chamber for which episode data are
ventricular collected.
Data collection Frozen or The Frozen method collects data for the
method Rolling first 15 High Rate Episodes (seven when
episodes EGM is selected). The Rolling method
continuously collects data for the most-
recent 15 High Rate Episodes (seven when
EGM is selected), overwriting the oldest
data if necessary.
EGM OFF or ON When ON, the number of episodes
collected is reduced to seven with an
approximately two second EGM
with simulated pacing pulses
for one High Rate Episode.
