14. IMPLANT PROCEDURE
In the case of an external defibrillation shock delivered to the patient, always check the
programming and functioning of the device, in particular its capacity to deliver shocks.
14.11. DEVICE IMPLANTATION
INTENSIA VR 124 should be implanted with the engraved side facing outwards for optimal
communication with the programming head and radiographic identification.
Carefully wind excess lead and place in a separate pocket to the side of the defibrillator.
It is recommended to not place any excess wire between the can and the heart.
Suture the casing connector to the muscle using the hole provided for this purpose, in order
to avoid potential migration of the device into the pectoral muscle.
14.12. TESTS AND PROGRAMMING
During the implant testing procedure, it is recommended that a security margin of at least 10
J be demonstrated between the effective shock energy and maximum programmable
energy.
Enable shock therapies, then program the defibrillator.
Verify that the defibrillation lead impedance for each shock delivered ranges from 30 to 150
ohms. Check the lead connection if the values are outside these boundaries.
Save the programming data on the programmer’s hard disk and on an external storage
device (if desired).

NOTE: To optimize cardioversion/defibrillation shocks, electrodes must be positioned so that
the electric field between anode(s) and cathode covers the largest myocardial mass. In
normal conditions, the anode and cathode are adequately separated. In case of a short-
circuit, the shock may be aborted to prevent damaging the defibrillator.
