Marquette™ 12SL ECG analysis program

The Marquette 12SL ACS tool* increases sensitivity for ST-Elevated MI or Acute Ischemia in patients suspected of having an acute cardiac event. 

The tool heavily weighs the finding of ST elevation with reciprocal ST depression. This is a very important and highly-specific indicator of STEMI and ACS that has been found to “identify patients who stand to benefit most from early interventional strategies.”³ 

A study evaluated on over 1,900 clinically correlated ECGs from patients suspected of having ACS showed that the ACS tool improved the sensitivity of emergency physicians’ interpretation of acute myocardial infarction by 50% and cardiologists’ interpretations by 26%, with no loss of specificity.⁴

The Marquette Serial Comparison Program indicates changes in the ECG from the previous ECG of the same patient. 

It utilizes interpretive statements, ECG measurements and waveform comparison techniques to maximize accuracy in the detection of clinically significant changes. 

Exceeding current standards for 12- and 15-lead measurements and analysis, it ensures reproducibility and objectivity for increased efficiency in the process. 

Serial comparison requires the MUSE™ ECG management system.

It’s well recognized that the identification of prolonged QT is important, as the condition can result in serious arrhythmia and Sudden Cardiac Death.⁵ 

However, it can be difficult to measure QT accurately due to factors such as ECG noise, difficulty defining the end of the T wave, and requiring corrections for heart rate. 

We’ve concentrated our efforts in helping to minimize these challenges through the Marquette 12SL program. 

The QT is measured from a median complex reducing the influence of noise, it’s also measured from global fiducial points from all 12 simultaneous leads. 

In conjunction with MAC VU360™, MAC™ 7, and MAC™ 5, the Marquette 12SL provides analysis for detecting bi-ventricular pacemakers, identifying the underlying rhythm, in addition to the chamber(s) being paced—sampling at a rate that is much greater than is required for conventional ECG analysis. 

The pacemaker annotation channel will then be displayed on the ECG printout and on the MUSE ECG management system.

Children are not the same as adults and neither are their ECGs. Equally, adult men and women are different and this difference extends to the ECG. 

The Marquette 12SL features Gender-Specific interpretation that applies criteria for evaluating the ST segment and T-wave of the ECG waveform to enhance diagnostic confidence. 

It improves the sensitivity for detection of acute anterior MI from 42% to 48% in women under 60 years of age,⁶ and has a 25% relative improvement in detection of acute inferior MI in women under 60.⁷

Accurate pediatric specific measurement and interpretation has been validated by an independent study with over 1,100 pediatric ECGs.⁸
