QRS Universal ECG

-Automatic narrative interpretation and measurement analysis using the advanced Louvaine Algorithm, which has the best total accuracy 1 when compared to leading competitors.

- Print full page reports on standard plain paper in portrait, landscape or A4.

- Review and zoom into data with electronic calipers, enter comments and modify the interpretation before confirming the results.

-Instantly create PDFs or JPEGs of the final report. - Seamlessly integrate ECG data into your EMR via XML, HL7 and other formats.

-Also available in a 6-channel non-interpretive version.

The Universal ECG is the smallest and lightest 12 lead EKG on the market. Perform resting ECG anytime, anywhere with unparalleled ease-of-use.

 

The ECG includes everything you need to start testing. Simply connect to your favorite PC, laptop or handheld and you are ready to begin.

Results are displayed on-screen for quick assessment.

 

A full set of diagnostic measurements are automatically interpreted by the advanced Louvaine Algorithm. Connect via CF/PC Card Slot, Serial or USB port.

 

Accuracy:

 

The Universal ECG uses the Louvaine analysis program. In 1991, clinical researchers evaluated nine popular ECG algorithms compared to eight cardiologists relative to a standardized database of ECG tracings.

The Louvaine algorithm had the best total accuracy of all the algorithms (77.3%) evaluated. It was also the best in correctly diagnosing Myocardial Infarction (82.1%) and the second best in diagnosing Ventricular Hypertrophy, which were both better than the respective combined scores of the eight cardiologists.
