102 Estella Pulse Generators Technical ManualIf the magnet effect is set to asynchronous, the AV delay is reduced to100 ms (or the programmed AV delay, whichever is shorter). Shorteningof the AV delay to 100 ms during asynchronous AV sequential stimulationis provided to avoid ventricular fusion beats in the presence of intactAV conduction. This allows efficient diagnosis of ventricular capture orfailure to capture.Synchronous Magnet Effect:If the magnet effect is programmed to synchronous operation, magnetapplication does not affect timing and sensing behavior of the pulsegenerator. Synchronous operation is of particular importance duringfollow-up, if sensing and inhibition functions are desired during magnetapplication.Trend monitor and event counter operation is interrupted during anymagnet application.9.3 Temporary ProgrammingCautionOFF Mode—Use of the OFF mode should be avoided inpacemaker dependent patients. The OFF mode can betransmitted as a temporary program only to permit evaluationof the patient’s spontaneous rhythm.A temporary program is a pacing program which remains activated whilethe programming head is positioned over the pulse generator. Uponremoval of the programming head (at least 15 cm away from the pulsegenerator), the temporary program will be automatically deactivatedand the permanent program will again be in effect.Generally, every pacing program displayed on the programmer screenmay be transmitted as a temporary program by pressing the keydesignated on the programmer keyboard. With few exceptions, thisalso applies to pacing programs containing a parameter conflict,which cannot be programmed as permanent programs. Temporaryprogramming facilitates follow‐up and enhances patient safety. Testprograms affecting patient safety, like pacing threshold measurementsin a pacemaker‐dependent patient, should be activated as a temporaryprogram only.When interrogating the pulse generator, the permanent program willalways be displayed and documented, even though a temporary programwas activated during the interrogation.
