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).
16.6. FOLLOW-UP FUNCTIONS
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 the programmable EGM channels: either by
selecting up to two traces, or by selecting "V-Double" which enables
a one-channel recording that is twice as long.
Diagnosis of AV conduction: Automatic diagnosis of AV
conduction with graphic displays.
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 as a
warning (pop-up message) to notify immediately the user. For
example, the following types of event can trigger a warning or an
alert: technical problem during a shock, pacing lead impedance or
coil impedance measurements out-of-range, battery depletion, …
