Pinnacle 8820 SSI (Multiprogrammable)

Pinnacle pacemaker is 8 Parameter multi-programmable Implantable Pulse Generator. Pinnacle has Digital Algorithm for automatic threshold measurement facility for tension free pacing even if the threshold is changing between acute and chronic levels. Once automatic feature is enabled the pacemaker itself settles down to an optimum pacing amplitude. When a loss of capture is detected pacemaker immediately increases its amplitude up to 4.5 Volts to maintain pacing, after 4.5Volts Automatic feature is disabled and pacing polarity is changed to Unipolar for effective pacing (eliminating defect caused by outer lead fracture).
