What's new to the market
There are only a handful of OEMs who deal with stress test equipment, with the big players being Cardiac Science (which manufactures the direct descendents of Quinton's designs and products, having acquired the company in 2005), GE and their Marquette line, and Nasiff Associates, Inc.

Today's models have improved hardware, software and the ability to export data, electronic records and clinical measurement tools and the OEMs are focusing on improved technology, easier workflow solutions, EMR compatibility or integration, making diagnostic systems complete systems and adding protocols in stress systems.
GE has recently advanced networked stress testing solutions and workflow enhancements to allow physicians to review and view multiple live tests from any location.
"Computer algorithms have been advanced to provide diagnostic quality EKG even during 'noisy' procedures," say Brooks. "Other advancements include automated arrhythmia analysis, very high levels of system and procedure customization and increased use of imaging modalities along side the EKG data."
In October of 2008, Cardiac Science launched the new Quinton Q-Stress 4.0, the ninth generation of its diagnostic stress testing technology and one of the most requested brands on the refurbished market today.
The new Quinton Q-Stress connects with virtually everything needed for enhanced workflow and reporting, including hospital information system/electronic medical record systems, e-mail, network storage, and nuclear and echo systems. Every heartbeat can be captured and reviewed and the entire test can be saved and sent to a desktop workstation, network, or EMR for storage and remote viewing.
"Clinicians rely on Quinton Q-Stress for consistent, durable, and reliable performance," says Rene Mitchell, Cardiac Science director of diagnostic marketing "Q-Stress 4.0 incorporates stress testing innovations with the efficient workflow and ease of use."
Roger Nasiff, President of Nasiff Associates, Inc., is getting ready to provide a complete turn-key stress system at an affordable price, in an effort to keep up with customer demand.
