Pulse form
The pacing pulse has the following form:
The pulse amplitude reaches its maximum value
at the beginning of the pulse (Ua). With
increasing pacing duration (tb), the pulse
amplitude is reduced dependent on the pacing
impedance.
Resistance to interference
All variants of BIOTRONIK devices comply with the requirements of prEN 45502-2-1:
2006, § 27.5.1 at the highest sensitivity.

The following data is provided by the manufacturers:
Shortening of the service time after long storage period
Depending on the storage period, the service time from the beginning of service BOS to
the replacement time ERI decreases as follows:
• After 1 year by three months
• After 1.5 years by four months
Power consumption
• BOS, inhibited: SR(-T), DR(-T) 6 µA; HF-T: 7 µA
• BOS, 100% pacing: SR(-T) 9 µA; DR(-T) 14 µA; HF-T: 18 µA
Calculation of service times
Mean service times are valid for devices with and without Home Monitoring; they are
pre-estimated from the following and other data:
• Technical data of the battery manufacturer:
• Basic rate of 60 bpm in AAIR/VVIR modes (single-chamber devices) or DDDR modes
(dual-chamber and triple-chamber devices)
• Home Monitoring configuration: OFF
• With 10-minute RF telemetry twice a year as well as without RF telemetry
• Configuration of different pulse amplitudes and lead impedances
Mean service times SR(-T)
For single-chamber devices, the following times (in years) result:
