The “BAIKAL SC” SSI-type 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 the UNI programmers.

The Pacemaker offers the following functions:

• protection against tachycardia
• time programming with pulse repetition rate of 30 to 450 ppm
• measurement of electrode impedance in a range from 100 to 3000 ohm

The Electric Pacemaker has reduced teardropshaped design.

Implantation of the Pacemaker is carried out in cardiologic centres or cardiosurgery departments.

Telemetering information:

• model and serial number
• programmable parameters of stimulation
• battery condition
• statistics: imposed or perceived events
• impedance of electrode

The Pacemaker's operation mode can be altered prior or after implantation by reprogramming the following parameters:
