104 <strong>Estella</strong> <strong>Pulse</strong> <strong>Generators</strong> Technical Manual9.5 Position IndicatorThe position indicator facilitates positioning of the programmer head.The programmer optically and acoustically indicates whether theprogrammer head is in communication with the pulse generator.9.6 Pacing When Exposed to InterferenceCautionEMI—Computerized systems are subject to EMI or “noise”. Inthe presence of such interference, telemetry communicationmay be interrupted and prevent programming.A sensed event occurring during the interference interval willcontinuously reset that interval for the corresponding chamber withoutresetting the basic interval. Depending upon whether the interference(electromagnetic interference, muscle potentials, etc.) is detected by theatrial and/or ventricular channel, atrial and/or ventricular asynchronouspacing at the programmed timing intervals will result for the duration ofthe interference. The interference interval has a duration of 51 ms.Depending on the programmed pacing mode and the channel in whichelectromagnetic interference (EMI) occurs, Table 30 details the resultingpacing modes for the duration of exposure to EMI.Table 30: Response to EMIMODE EMI* (A) EMI* (V) EMI* (A+V)DDD(R)DDI(R)DVI(R)VDD(R)VVI(R)AAI(R)DDTVDIVVTAATDVDR---DVD(R)DVI(R)---VVI(R)---AOO(R)VVTVVT---AOODADRVOORDAD(R)DAI(R)DOO(R)VAT(R)VOO(R)---VATVOOVOO---DOOR---DOO(R)DOO(R)---VOO(R)------VOOVOO------* EMI = Electromagnetic Interference
