Lumax Technical Manual 137
 If an ongoing atrial episode fulfills a programmed time
duration criteria, a message is triggered to provide the
physician with the information early on.
 For the periodic IEGM only a pre-detection-part is
available, recording of this episode is performed right
before a periodic message, as often as configured.
The Lumax ICD/CRT-D transmits the following data from the
Episode List with the IEGM message:
 Episode Number,
 Date and time of initial detection,
 Date and time of termination,
 Indication of magnet application (induced episode and
forced termination)
 Zone of Initial Detection,
 Number of delivered ATP and shocks during this episode,
 Number of redetections per zone
 SMART Detection setting (VT zones activated)
 SMART path (for SVT)
 Duration of episode
The following markers are also transmitted: A
S
(including A
rs
), A
P
,
V
S
(including V
rs
), V
P
, VT1, VT2, VF, SVT (atrial and refractory
sensed events included with sensed events), and AF.
The IEGM Online HD from the most recent episode is stored in
the device in an IEGM data buffer. The firmware updates the
IEGM transmission buffer before the first IEGM transmission
episode. IEGM data from a VT/VF episode is available after
Termination detection of an episode. If the Holter configuration
records an SVT IEGM episode, the IEGM data from an SVT
episode is available after Termination detection of an episode. An
IEGM message is transmitted with daily, periodic IEGM, and
episode messages (unless already sent). An IEGM is not sent
with programmer triggered and ROM/EOS messages.
The Lumax ICD/CRT-D includes a programmable parameter to
disable or enable the IEGM transmission. The default value is
“enabled.”
