Designed to meet your needs
The CASE System was developed only after we used Six Sigma principles to listen to our customers. As a result, it addresses your need for productivity-enhancing ease of use, powerful diagnostic tools and leading-edge networking alternatives. And its open architecture accommodates a range of increasingly powerful capabilities.
Innovative ergonomics
The CASE System’s exclusive ergonomic features include a backlit keyboard and well-lit printing surface for effortless and confident operation in rooms darkened for stress-echo tests. A centrally mounted, full-size monitor swivels for comfortable viewing. A familiar, Windows® NT-based interface and dedicated hard keys minimize the learning curve. And a flexible interface accommodates multiple custom set-ups, to meet the review and reporting preferences of any physician.
Enhanced diagnostic confidence
CASE offers a variety of powerful analysis tools and easy-to-use applications to optimize clinical decision-making – including robust analysis and measurement algorithms. Multi-lead arrhythmia detection. And advanced assessment tools such as the proven 12SL™ computer-interpreted 12-lead ECG analysis.
It also gives you access to such capabilities as full disclosure, incremental updating, Duke Treadmill Score, cubic spline and automatic arrhythmia detection. And its signal-acquisition advances and innovative filtering – including Finite Residual Filtering – are complemented by user-adjustable controls for performance fine-tuning.
High-productivity networking
CASE can also be configured to meet information-management requirements from the simplest to the most sophisticated. For example, it accommodates bi-directional network communications for remote access to MUSE-stored patient records. Gives you the ability to export Adobe pdf and Word files, as well as XML and ASCII measurement data. And lets you seamlessly retrieve reports stored on the MUSE system – even echo and nuclear procedure reports.
