Life Systems Medical Pty. Ltd. is an Australian company that provides advanced patient therapy devices such as cardiac pacemakers, cryotherapy devices, catheters for thoracic pacing, SurgiFrost console and probes, Spectranetics Excimer lasers and Holter monitors. Symphony cardiac pacemakers supplied by the company are highly sophisticated devices that have been designed with multiple features and do not feature the large volume or weight of conventional devices. Symphony cardiac pacemakers come with the advanced AAISafeR function, which provides safe treatment for cardiac patients.
The AAISafeR mode in cardiac pacemakers offers benefits such as dual sensor rate response, mode switching and anti PMT. These pacemakers incorporate AF prevention algorithms to avoid overdriving, pause suspension and acceleration on PACs. These cardiac pacemakers are very reliable in sensing atrial events and their sensitivity can be programmed down to 0.1mv as well as short automatic refractory periods. The AAISafeR feature periodically checks the AV conduction during the first hour of programming. If any anomaly is detected and AV conduction is impaired, it paces in DDD permanently. Cardiac pacemakers attempt to restore AAI pacing every morning and switch back to DDD if the intrinsic condition is not detected.
