- Additional Technical Information
• Ventricular refractory periods (VRPs) in adaptive-rate pacing. Adaptive-rate pacing is not limited by
refractory periods. A long refractory period programmed in combination with a high M SR can result in
asynchronous pacing during refractory periods since the combination can cause a very small sensing
window or none at all. Use Dynamic AV Delay or Dynamic PVARP to optimize sensing windows. If you
are entering a fixed AV Delay, consider the sensing outcomes.
• Shock waveform polarity. For IS-1/DF-1 leads, never change the shock waveform polarity by physically
switching the lead anodes and cathodes in the pulse generator header—use the programmable Polarity
feature. Device damage or nonconversion of the arrhythmia post-operatively may result if the polarity
is switched physically.
• Tachy Mode to Off. To prevent inappropriate shocks, ensure that the pulse generator’s Tachy Mode is
programmed to Off when not in use and before handling the device. For tachyarrhythmia detection and
therapy, verify that the Tachy Mode is programmed to Monitor + Therapy.
• Atrial oversensing. Take care to ensure that artifacts from the ventricles are not present on the atrial
channel, or atrial oversensing may result. If ventricular artifacts are present in the atrial channel, the
atrial lead may need to be repositioned to minimize its interaction.
• ATR entry count. Exercise care when programming the Entry Count to low values in conjunction with
a short ATR Duration. This combination allows mode switching with very few fast atrial beats. F or
example, if the Entry Count was programmed to 2 and the ATR Duration to 0, ATR mode switching c ould
occur on 2 fast atrial intervals. In these instances, a short series of premature atrial events could cause
the device to mode switch.
• ATR exit coun t. Exercise care when programming the Exit Count to low values. For example, if the
Exit Count was programmed to 2, a few c ycles of atrial undersensing could cause termination of mode
switching.
• Proper program mi ng without an atrial lead. If an atrial lead is not implanted (port is plugged instead),
or an atrial lead is abandoned but remains connected to the header, device programming should be
consistent with the number and type of leads actually in use.
