16. MAIN FUNCTIONS
16.3. PACING
BTO (Brady Tachy Overlap):
Allows pacing in the slow VT zone, without affecting arrhythmia detection specificity.
Post-shock mode:
After any automatic shock therapy, the post-shock mode makes it possible to apply different
pacing parameters.
16.4. SENSING
Automatic Refractory Periods:
Optimize sensing and make the implant programming easier. These periods are composed
of a minimal Refractory Period and a triggerable Refractory Period. The duration of the
refractory periods lengthens automatically as needed.
Protection against noise:
Allows the distinction between ventricular noise and ventricular fibrillation. If the device
senses ventricular noise, the ventricular sensitivity is decreased until noise is no longer
detected. Ventricular pacing can be inhibited to avoid a potential paced T-wave.
Automatic sensitivity control:
Optimizes arrhythmia detection and avoids late detection of T-waves and over-detection of
wide QRS waves. The device automatically adjusts the sensitivities based on the ventricular
sensing amplitude. In case of arrhythmia suspicion or after a paced event, the programmed
ventricular sensitivity will be applied. The minimum ventricular sensitivity threshold is 0.4 mV
(minimum programmable value).
16.5. FOLLOW-UP FUNCTION
Storage of memory data:
AIDA+ (Automatic Interpretation for Diagnosis Assistance) software provides access up to 6
months of patient follow-up with day by day data collection, or up to 24 hours with hourly
data collection. Episodes of ventricular tachyarrhythmia are recorded with one
programmable EGM channel which can be selected, in addition to RV EGM.
Alerts / Warnings:
The device routinely performs security self-checks and technical measurements to ensure
system integrity. When system integrity is found to be at risk outside a follow-up, alerts are
stored in the device memory. When system integrity is found to be at risk during a follow-up,
the information is managed by a warning (pop-up message) to immediately notify the user.
For example, the following types of event can trigger a warning or an alert: technical
problem during a shock, lead impedance or shock continuity measurements out-of-range,
battery depletion, …
16.6. REMOTE MONITORING FUNCTION
Remote monitoring enables the automatic remote transmission of implant data to the
physician thanks to the wireless Radio Frequency (RF) communication ability of the implant
in order to provide a comprehensive report to the physician about device functioning and
patient cardiac status without having the patient physically in the clinic.
