The BAIKAL-DC DDD-type Dual-Chamber Implantable Telemetering Electric Pacemaker is intended for treatment of atrioventricular heart blocks at Morgagni-Stokes syndrome and other cardiac 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, measurement of electrodes’ impedance, extensive statistics of the events’ array displayed as convenient histograms and protection against pacemaker-mediated tachycardias.

Telemetering information:

• model and serial number
• programmable parameters of stimulation
• battery condition
• impedance of electrode

Statistics:

• imposed events via A and V channels
• perceived events via A and V channels
• combination of imposed/perceived events
• quantity of changeovers in stimulation mode
