Pacemaker
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).

Service Life
The expected life of the generator, pacing 100% at 70 ppm, with 2.5 V amplitude and pulse width of 0.4 ms, is 10.2 years.
Telemetry Data
Real time telemetry with holter analysis trends.
Parameters: All the programmable parameters.
Identification: Model and serial number
Battery condition: Voltage, ERI and EOL indicators
Threshold measurements
Statistics: Keeps track of pacing and sensing events, as well as ventricular premature events. Frequency Histogram.
Lead Impedance
Marker Pulses.
Temporary Programming
Protections
Noise detection: When the pacemaker senses events with frequency exceeding 11 Hz, it switches to VOO mode.
Run Away Limit: The pacemaker includes an antirunaway circuit to avoid the generation of stimuli with a rate over 200 ppm (except in temporary programming).
Programming
The pacemaker is programmed using a microcomputer (usually a Laptop) that runs Windows operating system. It is required to use ALUS programming interface and Wand for programming custom made for Pacetronix Pacemakers. It also permits the measurement of the stimulation and sensing thresholds as well as the generation of printed reports.
