TECHNOLOGY
Premier Heart's MCG (Digital, Database-Driven Multiphase analysis / Multiphase Functional Electromyocardial Tomography) System represents a radical departure from traditional resting and stress ECG techniques — where medicine has historically taken a reductionistic view of the ECG, the mfEMT (multiphase functional electromyocardial tomography) technology employed in our MCG units uses an integrative approach, building a mathematical model of the entire cardiac system.
In short, rather trying to simplify its view of the heart, mfEMT embraces the system in all of its complexity, enabling us to obtain accurate diagnoses from a simple, non-invasive test.

How it Works
Premier Heart's system consists of three stages:
- First, a MCG Field Unit is used to digitally record resting ECG data from the patient. This process is similar to a standard resting ECG and can be performed quickly and easily in nearly any setting.
- The ECG data is then forwarded to Premier Heart's datacenter via an encrypted Internet connection.
- The numeric score and identified conditions are compiled into an easy-to-read report which the physician can review on the MCG unit, or any computer with a web browser and PDF viewer.
- Sample reports for normal and abnormal patients are available
How it Compares
When compared to other diagnostic modalities, MCG™ is extremely accurate and reliable, surpassing many established clinical techniques in both sensitivity and specificity. In addition, MCG™ is capable of accurately detecting coronary artery disease at earlier stages (<70% lumen encroachment), and surpasses many invasive techniques in this capacity.

How can MCG provide better accuracy with 2 leads compared to a conventional 12-lead ECG?
The key to MCG's accuracy is in the mfEMT analysis algorithms — mfEMT offers several advantages over a conventional ECG, notably:
- The mfEMT Analysis expands the analog ECG signal into a series of mathematical functions, more closely representing the complexity of a living heart.
- mfEMT analysis compares the results of the above functions to a clinically validated database containing in excess of 35,000 patients, including healthy individuals and those with pathologies confirmed through conventional diagnostic modalities.
- The breadth of the mfEMT database exceeds the capacity of an individual clinician reviewing a conventional ECG.
- The accuracy of the mfEMT analysis is not affected by most abnormalities in the resting ECG, (arrhythmia's, gender or age) due to the nature of the analysis, which focuses on the relationship between two leads as opposed to the traditional method of analyzing complexes (P, QRS, S-T, etc.).
- mfEMT views the ECG data in both the time domain (as a conventional ECG) and the frequency domain, using experimentally proven and empirically validated signal processing techniques to extract latent information from the ECG signal which is not available with conventional techniques.
Benefits of MCG™
In addition to easing the burden of urgent care providers and primary care physicians who may lack the expertise in cardiology necessary to detect the subtle variations in the ECG that can indicate potentially life-threatening conditions, MCG™ provides the following benefits:
Rapid and Timely
a MCG test session and mfEMT analysis can typically be completed within 5-7 minutes, allowing the technology to be applied as part of routine care and screening by primary care physicians as well as for screening of patients with acute symptoms of cardiac distress.
Objective
The mfEMT diagnostic process is purely evidence based, drawing its diagnoses based upon previous clinically verified results. This combined with the integrative approach to modeling the heart and Premier Heart's scoring system allows us to provide quantitative and objective results.
Non-Invasive and Stress Free
A MCG test session involves only a surface resting ECG, and does not share the risks, expense or contraindications of other diagnostic procedures such as stress tests, Cardiac MRI or nuclear perfusion imaging.
