Service Life

The expected life of the generator, pacing 100% at 70 ppm, with 3.6 V amplitude and pulse width of 0.4 ms, is 9.2 years.

The expected life of the generator, pacing 100% at 60 ppm, with 2.5 V amplitude and pulse width of 0.4 ms, is 12.6 years.


Telemetry Data


Parameters: All the programmable parameters.


Identification: Serial number


Battery condition: Voltage, ERI and EOL indicators Threshold test by Pulse width and sensing available.
Statistics: Keeps track of pacing and sensing events, as well as ventricular premature events.

Marker Pulses.


Noise detection: When the pacemaker senses events with frequency exceeding 11 Hz, it switches to VOO mode.
Run Away Limit: The pacemaker includes an antirunaway circuit to avoid the generation of stimuli with a rate over 200 ppm (except in temporary programming).



The pacemaker is programmed using a Laptop that runs Windows 98 / 2000 / XP operating system. The programming system includes Log of Pacemaker History. It also permits the measurement of the stimulation thresholds using Pulse width. Top
