Storage period
The storage period affects the battery service time.
• Devices should be implanted within 19 months between the manufacturing date
and the use by date (indicated on the package).
• If the ICD is implanted shortly before the use by date, the expected service time
may be reduced by up to 16 months.
Calculation of service times
• The services times have been calculated as follows – in all chambers depending on
the device type:
— Pulse amplitude: 2.5 V
— Pulse width: 0.4 ms
— Pacing impedance: 500 Ω
— Basic rate: 60 bpm
— Home Monitoring: ON, 1 device message each day and 12 IEGM online HD
transmissions per year
— Diagnostic functions and recordings: permanently set
• Capacitor reforming is performed 4 times per year and therefore at least
4 maximum charges for shocks have to be assumed per year even if less than 4 are
delivered.
Calculation of the number of shocks
Calculation of the maximum number of shocks: Service time [in years] x number of
shocks per year
