Phoenix AM pacemaker is 8 Parameter multi-programmable Implantable Pulse Generator. Phoenix AM 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). |

End of Service Indicators
|
| |
ERI (Elective replacement): When the remaining capacity of the battery is between 4 and 8%, the pacing rate switches to 85 ppm when a magnet is applied.
EOL (End of Life): When the remaining capacity of the battery is under 4% of the initial capacity, the pacing rate slows 10 ppm. |

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 Biopace Pacemakers. It also permits the measurement of the stimulation and sensing thresholds as well as the generation of printed reports.
