External defibrillation: PARADYM RF SonR CRT-D 9770 is
protected from external defibrillation shocks. Before external
defibrillation, deactivate ATP and shock therapies. During external
defibrillation, it is advisable to avoid placing the defibrillating paddles
directly over the casing or over the leads. The defibrillating paddles
should preferably be placed in an anteroposterior position. Avoid any
direct contact between the defibrillation paddles and the conductive
parts of the implanted leads or casing of the implanted device. After
external defibrillation, check for proper device function.
Radiation therapy: Avoid exposure to ionizing radiation. Betatrons
are contraindicated. If high doses of radiation therapy cannot be
avoided, the defibrillator should be protected from direct exposure
with a screen. ATP and shock therapies should be disabled during
exposure and proper device function should be checked regularly
afterwards. Resulting damage may not be immediately detectable.
If irradiation of tissues close to the implantation site is necessary, it is
recommended that the cardiac defibrillator be moved. As a safety
measure, an external defibrillator should be immediately available.
Lithotripsy: Lithotripsy may permanently damage the device if it is at
the focal point of the lithotripsy beam. If lithotripsy must be used,
keep the defibrillator at least 2.5 to 5 cm (1-2 inches) away from the
focal point of the lithotripsy beam.
Diagnostic ultrasound (echography): The defibrillator is not
affected by ultrasound imaging devices.
Scales with body fat monitors and electronic muscle stimulators:
A patient with an implanted PARADYM RF SonR CRT-D 9770 should not
use these devices.
