Medical Appliances / Cardiac Pacemakers



The “BAIKAL DC” DDD-type Dual-Chamber Implantable Telemetering Electric Pacemaker is intended for treatment of сardiac rhythm disorders by electric stimulation of ventricles or auricles.

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

Programmable by means of UNI programmers.

The Pacemaker implements an automatic switch of stimulation mode with constant analysis of activity within refractory periods, extensive statistics of the events’ array displayed as convenient histograms and protection against pacemaker-mediated tachycardias.

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;
  • events’ marker.


  • imposed events via A and V channels;
  • perceived events via A and V channels;
  • combination of imposed / perceived events;
  • Q-ty of changeovers in stimulation mode.
