76 Estella Pulse Generators Technical ManualAn ongoing SA/CV sequence will abort when the following events occur:• Mode Switch: Mode switch has a higher priority than the SA/CV. IfMode switch aborts an SA/CV, the device will be set to high output.After reversion back to the programmed mode, a new SA/CV will beinitiated.• Programmer Wand application: An ongoing SA/CV aborts when amagnet (programmer wand) is applied and the device is then set tohigh output. After removal of the magnet, a new SA/CV is started.• Search timer expiration (120 seconds): if the SA/CV takes longerthan 120 seconds to be completed (e.g. due to sensing), the SA/CVwill be aborted and the device will be set to high output.• Noise detection: if excessive noise is detected, the initial SA/CV willbe aborted and the device will be set to high output.A SA/CV sequence will be postponed when the following events occur:• Mode switch is ongoing: If Mode switch is ongoing when an SA/CV isscheduled, the SA/CV will be postponed until reversion back to theprogrammed mode.• The presence of a magnet is detected: A scheduled SA/CV ispostponed when a magnet (programmer wand) is detected. Afterremoval of the magnet, the SA/CV is started.• The ventricular rate is higher than 110 bpm: A scheduled SA/CV ispostponed when the ventricular rate is higher than 100 bpm. Whenthe ventricular rate drops below 10 bpm, the SA/CV is started.The continuous capture control (CV) will be suspended and the ventricularpacing amplitude is set to high output when the following events occur:• The ventricular rate is higher than 110 bpm: CV is suspended whilethe ventricular rate is higher than 110 bpm. When the ventricularrate drops below 110 bpm, CV is resumed.• Mode Switch: CV is suspended and the device is set to high outputuntil reversion back to the programmed mode.The VCC feature will be automatically turned OFF when the followingevents occur:• The initial SA/CV sequence after activating VCC failed• Three subsequent and consecutive failed SA attempts• The occurrence of 25 Losses of Capture between two consecutivedays• ERI: the device will be set to ERI mode with VCC OFF• Unipolar lead failure is detected
