9. Other Functions/FeaturesEstella Pulse Generators Technical Manual 101Estella pulse generators offer many additional functions and features toassist the physician in the care of the pacemaker patient.9.1 Safe Program SettingsActivating the preset values for the Safe Program is a quick andconvenient way to provide VVI pacing at a high output setting in urgentsituations. Listed in Table 29 are the Safe Program settings for Estellapulse generators.Table 29: Safe Program SettingsParameter Dual chamber Single chamberMode VVI VVIPacing Rate 70 ppm 70 ppmAmplitude 4.8 V (ventricle) 4.8 VPulse Width 1.0 ms 1.0 msSensitivity 2.5 mV 2.5 mV (ventricle)VentricularRefractory Period300 ms 300 msPacing Polarity Unipolar UnipolarSingle ChamberHysteresisOFFOFF9.2 Magnet EffectAutomatic Magnet Effect:After magnet application the pulse generator paces at 90 ppm for10 cycles asynchronously. Thereafter, the pulse generator pacessynchronously at the programmed basic rate. During asynchronouspacing, the AV interval is reduced to 100 ms.Asynchronous Magnet Effect:When programmed to asynchronous operation, magnet applicationresults in asynchronous pacing. The pulse generator pacesasynchronously at 90 ppm as long as the magnet is over the pulsegenerator. Upon magnet removal, the current basic interval is completedbefore the pulse generator reverts to its original operating mode.
