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).
