(EMAILWIRE.COM, November 05, 2002 ) Quinton Cardiology Systems, Inc. (Nasdaq: QUIN), a global leader in advanced cardiology products, announced today it began shipping Q-Stress® version 3.0 systems with expanded connectivity capability using Microsoft Windows XP operating system.

This latest version of Q-Stress substantially increases the amount of patient and clinical information automatically exported to facility information systems. Q-Stress version 3.0 formats patient and clinical study data into both XML (Extensible Markup language) and PDF (Portable Document Format). This data can be reviewed by the physician immediately, exported to the facility information system, stored to a repository for review later, or automatically sent to referring physicians and consulting cardiologists.

Using the widely accepted XML and PDF formats provides users with open, widely supported industry standard files, connectivity with other systems, and security. By formatting clinical information to XML, Q-Stress makes its data output compatible with a variety of information systems and removes the proprietary lock older systems had on data. With XML formatted data, users can import patient information directly into the Q-Stress system to improve efficiency, export clinical results to the facility database, and provide access to the report in PDF anywhere the physicians need it.

For example, when a patient has a Stress-Echo procedure, personal information can be downloaded directly onto the Q-Stress system, saving time and reducing errors. After the procedure, the patient's clinical results and ECG can be immediately combined with the echocardiography images and presented for review at a workstation. In the past, exercise stress and stress-echo or nuclear-stress images were presented on viewers or using VCR tapes, while stress EKG reports were on chart paper making a combined report impossible. The impact of this technology on the clinical workflow will dramatically improve efficiency and timeliness of diagnostic reporting.

"This is a dramatic improvement in the way clinicians generate, use and store information," stated Tyler Brown, Director of Marketing for Quinton. "By deploying Q-Stress 3.0 network, facilities can dramatically improve both the workflow and the diagnostic process by first combining, then presenting clinical data from multiple modalities to physicians where and when they want it," Brown continued. John Hinson, President of Quinton, added "We are taking full advantage of the convergence of several technologies - a common software platform in Windows, open standards like XML and PDF that many modalities can rely upon, networking infrastructure and the Internet. These enable Quinton to increase the value of our systems for users and leverage the diagnostic cardiac data we create for patients' and users' benefit. It is no longer enough to create better clinical data. You also have to provide benefits all along the data user-chain. As the market leader in stress, users recognize our ability to provide software solutions, meet their connectivity expectations and move forward with improvements such as Windows XP."

The Q-Stress Cardiac Stress System is an automated system that monitors patient's ECG during exercise protocols, pharmacologic studies, stress-echocardiograms, and nuclear studies. Physicians frequently employ echocardiography devices; a combined procedure called stress-echocardiography, and nuclear imaging to visualize the heart during peak exercise. During a prescribed cardiac stress procedure, patients typically try to reach a "target heart rate" via exercise. At or close to this target the heart generally reveal areas of cardiac weakness or coronary blockage. Blocked arteries reduce oxygen flow causing ischemia. This scenario is displayed on the patient's ECG waveform recorded by the stress monitoring system. Placing the stress of exercise on the heart, the test may expose abnormalities that are often not apparent at rest.

Quinton develops, manufactures, markets and services a family of diagnostic cardiology systems used in the diagnosis, treatment and rehabilitation of patients with cardiovascular disease. Quinton shares are quoted on the Nasdaq National Market under the trading symbol "QUIN".
