Offering exceptional value throughout the continuum of care, Marquette 12SL analyzes
simultaneously acquired 12-lead ECGs; makes precise measurements1 of recorded cardiac
signals; and provides an interpretation of the ECG waveforms using classic and newly
developed ECG interpretation criteria for both rhythm and morphology.
This computerized analysis program operates on a variety of platforms and currently serves
- Pre-hospital environment
- Emergency department
- General hospital departments
- Exercise testing labs
- Physician offices
Clinically validated improvements
Ever-focused on improving accuracy and enhancing patient care, Marquette 12SL is
continually refined through the following processes:
- Regular clinical input: Annual input is gathered from the world’s top consulting
cardiologists and physicians—focusing on research and development efforts.
- Clinically correlated databases: GE utilizes many different databases during the
development and validation process to enhance program accuracy. This helps
preclude us from developing an analysis program that works well on training sets of
ECGs, but cannot be applied with the same success to other populations.
Clinically correlated databases help to improve program accuracy, but
they also have limitations. Analysis programs must work with a wider spectrum of ECG data.
To accomplish this task, GE measures its analysis program performance on a large database
of ECGs (>150,000). This process confronts the program with multiple diseases and varying
degrees of abnormality. ECGs that change their analysis results due to program modification
can be further investigated with expert confirmation.
