Cardiac Science Quinton Q-Stress Test System Features

The Quinton Q-Stress is the hospital industry’s gold standard. New! Microvolt T-Wave AlternansTM for Q-Stress combines the industry’s leading cardiac stress test system with Cambridge Heart’s unique Microvolt T-Wave Alternans (MTWA) testing system, creating the most comprehensive, reimbursable cardiac risk-profiling system in the industry (US-only). The Analytic Spectral Method® (ASM) detects every-other-beat patterns unique to patients at increased risk by analyzing the ECG in the frequency or spectral domain. Data shows that using frequency is superior at filtering out noise and artifacts than using timing alone.

Its easy-to-learn left-to-right workflow, simple-to-understand icons, and intuitive controls guide technicians through the stress test. Busy stress labs use QuikLists to enter comments quickly and efficiently.

Its proprietary algorithm, baseline wander, and motion artifact filters reduce noise and produce clean ECG tracings even at high speeds and steep grades. Perfect for pharmacological stress tests as well. Patients will appreciate getting the best test results the first time.

And Q-Stress is HL7 and DICOM compatible! Q-Stress has the flexibility to connect to the Healthcare IT systems in the way that works best to enhance the clinical workflow.
