Medical Appliances / Cardiac Pacemakers



The “BAIKAL DDD” DDD-type Bilocular Implantable Telemetering Electric Pacemaker is intended for treatment cardiac rhythm disorders by electric stimulation of ventricles and atriums.

Adopts unipolar or bipolar electrodes with IS-1 (3.2 mm) standard tips.

Programmable by means of UNI programmers.

The Pacemaker offers the following functions: automatic switching of stimulation mode with permanent analysis of activity within refractory periods, extensive statistics of the events’ array displayed as convenient histograms and protection against tachycardia.

The pacemaker implements the time programming with pulse rate of 30 … 460 ppm, measurement of electrode impedance of 100 to 3000 ohm, extra stimulation mode with maximum amplitude and widht of stimulative pulse.

Telemetering information:

  • model and serial number
  • programmable parameters of stimulation
  • battery condition
  • impedance of electrode
  • event’s marker


  • imposed events (A and V channels)
  • perceived events (A and V channels)
  • combination of imposed / perceived events
  • number of switching in stimulation mode
