CASE Cardiac Assessment System for Exercise Testing

CASE Exercise Testing System
A broader perspective on cardiac patient management

GE’s CASE® Exercise Testing System helps you put data in motion, with powerful analysis and diagnostic tools that streamline the process of data acquisition and review.

Known for robust ECG signal quality and clinical accuracy, the CASE system also provides a suite of advanced measurements to help you manage a variety of CVD patient groups.

  • Coronary artery disease (CAD) – CASE is the only stress solution to use ST/HR Hysteresis analysis, shown to improve the accuracy of CAD detection.
  • Sudden cardiac death – The CASE system provides critical algorithms – including the patented T-wave Alternans (TWA) algorithm – to assist you in predicting patients at risk of sudden cardiac death Cardiovascular disease monitoring – Metabolic equivalent (METS) level achieved during exercise testing is an important predictor of adverse cardiac events after myocardial infarction. Failure to achieve  METS during treadmill exercise is associated with a worse prognosis.

The T-2100 treadmill can be purchased with this system, and can interface with the CASE® Exercise Testing System and many legacy products. The T-2100 treadmill’s extra-long, 60-inch surface provides an extra margin of safety for patients. Its zero start feature slowly builds up speed for safe and smooth operation. And it can be slowed to a gradual stop, or stopped immediately with the standard emergency stop button. Full front and side handrails are also standard on the T-2100 treadmill.

CASE to MUSE workflow

Seamless stress

The design of the MUSE® cardiology information system was an exercise in workflow efficiency.

The MUSE exercise testing module has been reconfigured to synchronize with the information delivered from GE’s CASE® exercise testing system for consistent data compatibility. What’s more, the MUSE system’s Stress Editor interface has been completely redesigned to support and display the familiar configured report formats that are generated in the CASE system.

This module allows clinicians to efficiently edit their stress reports on the MUSE system, freeing up their CASE system to do what it does best – perform exercise testing.

As a result, this new workflow boosts stress lab productivity. So editing and reporting are easier. More comfortable. Faster. In effect, stress free.

Stress Editing Workflow

The MUSE Stress Report Editor supports exercise testing data from both GE’s CASE and CardioSoft™ (CS) Diagnostic Systems. A report preview of the CASE configured report and ECG strips is displayed as part of the stress final report configuration.

Features and Benefits

Case System

  • The CASE system is the only exercise testing system that uses GE’s acclaimed Marquette 12SL interpretive ECG program for accurate pre-test and recovery 12-lead analysis.
  • Digital signal processing at the point of acquisition and innovative noise-handling algorithms ensure clear, well-defined ECG tracings, accurate data and better patient care – even in the high-noise stress environment.
  • The Marquette T-Wave Alternans analysis program (TWA) provides an additional tool for predicting sudden cardiac death.
  • Not only does the CASE system store full disclosure data, it also allows clinicians to create 12-lead ECGs and analyze arrhythmias during post-test review.
  • Using GE’s patented finite residual filter, customers obtain the highest quality ECG without sacrificing waveform fidelity.
  • Bidirectional communication with the MUSE® cardiology information system streamlines workflow in the hospital between the CASE system and the Hospital Information System (HIS).
  • A backlit keyboard, well-lit work surface and swiveling, full-size monitor make it easier than ever to manage patients in rooms darkened for stress echo studies.
  • The highly-scalable CASE system can be readily configured to the requirements of any size facility today – and lets you add more capabilities as your needs and applications evolve.
  • The CASE system seamlessly integrates with Centricity® Physician Office – EMR for improved workflow in the physician office.
