Magnet application
Bringing a magnet close to the device triggers changes in device
operation as shown in Table 1-2. When the magnet is removed,
the device returns to its programmed operations.
For information on demonstrating Patient Alert tones to the
patient, see “Instructing the patient” on page 288.

Projected longevity
Projected longevity
Longevity estimates are based on accelerated battery discharge
data and device modeling, EGM pre-storage off, with:
■
2.5 V atrial and RV pacing amplitude, 3 V LV pacing amplitude,
0.4 ms pulse widths, and 30 J delivered therapy energy
(see Table 1-3)
■
3 V atrial and RV pacing amplitude, 4 V LV pacing amplitude,
0.4 ms pulse widths, and 30 J delivered therapy energy
(see Table 1-4)
Considerations for using EGM pre-storage – When the EGM
pre-storage feature is programmed off, the device starts to store
EGM following the third tachyarrhythmia event and also provides
up to 20 seconds of information before the onset of the
tachyarrhythmia, including:
■
AA and VV intervals
■
Marker Channel
■
interval plot Flashback
When the EGM pre-storage feature is programmed on, the device
also collects up to 20 seconds of EGM information before the
onset of the arrhythmia.
In a patient who uniformly repeats the same onset mechanisms,
the greatest clinical benefit of pre-onset EGM storage is achieved
after a few episodes are captured. To maximize the effectiveness
of the EGM pre-storage feature and optimize device longevity,
consider these programming options:
■
Turn pre-storage on to capture possible changes in the onset
mechanism following significant clinical adjustments, for
example, device implant, medication changes, and surgical
procedures.
■
Turn pre-storage off once you have successfully captured the
information of interest.

The longevity of the device is dependent on several factors. The
following factors result in decreased longevity:
■
an increase in pacing rate, pacing amplitude or pulse width;
the ratio of paced to sensed events; or the charging frequency
■
a decrease in pacing impedance
■
using the pre-onset EGM storage feature or Holter telemetry

Replacement indicators
Replacement indicators
Battery voltage and messages about replacement status appear
on the programmer display and on printed reports. Table 1-5 lists
the Elective Replacement Indicator (ERI) and the End of Life
(EOL) conditions.
Table 1-5. Replacement indicators
Elective Replacement (ERI)≤ 2.62 V
End of Life (EOL)3 months after ERI
ERI date – The programmer displays the date when the battery
reached ERI on the Quick Look and Battery and Lead
Measurements screens.
Temporary voltage decrease – The battery voltage temporarily
decreases following a high voltage charge. If a battery
measurement is taken immediately after a high voltage charge,
the ERI or EOL indicator may be displayed. However, this is a
temporary status which will return to normal when the battery has
recovered from the charge.
EOL indication – If the programmer indicates that the device is at
EOL, replace the device immediately.
Post-ERI conditions – EOL device status is defined as three
months following an ERI indication assuming the following
post-ERI conditions: 0% DDD atrial pacing, 100% DDD RV and LV
pacing at 70 ppm (min
for LV; 500 Ω pacing load; and six 30 J charges. EOL may be
indicated before the end of three months if the device exceeds
these conditions.

using the Charge/Dump test (see Table 1-6).

These charge times are typical when the capacitors are fully formed.
High voltage therapy energy
The stored energy of the device is derived from the peak capacitor
voltage and is always greater than the energy delivered by the
device. Table 1-7 compares the programmed energy levels
delivered by the device to the energy levels stored in the
capacitors before delivery.

New and enhanced features
The following features are new or changed from the
7277 InSync Marquis ICD.
Patient management
Heart Failure Management Report – The HF report provides
counter, audit, and long term trend information about clinical
status and device operation. Topics include tachyarrhythmia
episodes, heart rate, percent pacing, and patient activity.
Rate Histograms Report – Rate histograms for atrial rate,
ventricular rate, and ventricular rate during AT/AF episodes are
provided upon interrogation.
Ventricular Sensing Episodes – This diagnostic tool provides
reports on extended periods of ventricular sensing to help the
clinician assess continuity of CRT delivery.
Quick reference
New and enhanced features
29
Cardiac resynchronization therapy
CRT recovery options – Three optional CRT features help to
maintain CRT:
■
Ventricular Sense Response provides ventricular pacing
in response to ventricular sensing to ensure that CRT
pacing is delivered as programmed.
■
Conducted AF Response dynamically adjusts and
smooths the pacing rate to maintain ventricular pacing
during conducted AT/AF episodes. (Conducted AF
Response does not provide therapy for atrial arrhythmias.)
■
Atrial Tracking Recovery temporarily shortens PVARP to
restore atrial tracking and CRT delivery when atrial events
fall in the refractory period following a sensed ventricular
event.
