It incorporates high quality 12-lead technology, intuitive design, and advanced large color touch screen that displays patient's 12-lead ECG in real time. The system can acquire, interpret and store up to 120 ECG records at any one time while also being able to print and send diagnostic ECG reports to Spacelabs' recently launched Sentinel Cardiology Management System.  

Deepak Chopra, Chairman and Chief Executive Officer of OSI Systems, stated, "Our commitment to R&D since acquiring Del Mar Reynolds in July 2006 is exemplified in our recent launch of the Sentinel Cardiology Management System and in todays announcement of the launch of evo and Voyager.
