INFORMATION FOR USE
PRECAUTIONS
• Left Ventricular Protection Period (LVPP). Use of a lo ng LVPP redu ce s
the maximum LV pacing rate and may inhibit CRT at higher pacing rates.
• Shunting energy. Do not allow any object that is electrically conductive
to come into contact with the lead or device during induction because it
may shunt energy, resulting in less energy getting to the patient, and may
damage the implanted system.
• Expected benefits. Determinewhethertheexpecteddevicebenefits
outweigh the pos sibility of ea rly device replacement for patients whose
tachyarrhythmias require frequent shocks.
• Device communication. Use only the designated PRM and software
application to communicate with this pulse generator.
Environmental and Medical Therap y Hazards
• Avoid electromagnetic interference (EMI). Advise patients to avoid
sources of EMI because EMI may cause the pulse generator to deliver
inappropriate therapy or inhibit appropriate therapy. Examples of EMI
sources are:
• Electrical power sources, arc welding equipment, and robotic jacks
• Electrical smelting furnaces
• Large RF transmitters such as radar
• Radio transmitters, including those used to control toys
• Electronic surveillance (antitheft) devices
• An alternator on a car that is running
• Elevated Pressures. Elevated pressures due to hyperbaric chamber
exposure of SCUBA diving may damage the pulse generator. The pulse
generator has been tested to function normally at 1.5 Atmospheres
Absolute (ATA) pressure or 15 ft (4.6 m) depth in sea water. For specific
guidelines prior to hyperbaric chamber exposure, or if the patient is
planning scuba diving activity, contact Technical Services at the number
shown on the back cover of this manual.
