Cardiac Science Corp. (NSDQ:CSCX) and eClinicalWorks signed a deal to integrate the data from a line of diagnostic monitoring devices into an electronic medical records system.

The agreement will give about 30,000 physicians the ability to send data from Cardiac Science’s Quinton and Burdick brands of ECG, cardiac stress test and Holter monitors with eClinicalWorks’ EMR system. Cardiac Science customers will use its HeartCentrix connectivity solution to connect the devices with the EMR system, part of the Bothell, Wash.-based company’s push to make its devices compatible with as many leading EMR offerings as it can.

That opens up CSCX’s customer base of about 65,000 customers to the Westborough, Mass.-based EMR provider. Its own customer base amounts to about 30,000 physicians, according to a press release.

eClinicalWorks also sells its EMR product into the correctional market. The company inked a deal with Correctional Medical Services Inc., a provider of health services for 200 prisons and jails in 17 states across the country for EMRs for about 200,000 prison inmates across the U.S.

Cardiac Science posted third-quarter sales of $38.9 million for the three months ended Sept. 30, down 28 percent compared with $54 million during the same period last year. CSCX slipped into the red during the quarter, reporting a net loss of $66.6 million, compared with net income of $2.5 million during Q3 2008.
