Premier Heart's MCG System represents a radical
departure from traditional resting and stress ECG techniques — Where
medicine has historically taken a reductionistic view of the ECG Premier Heart's
MCG technology uses an integrative approach, building a mathematical model of
the entire cardiac system. This approach allows MCG to obtain accurate
diagnoses from a simple, non-invasive test.
How it Works
Premier Heart's system consists of three stages:
First, an MCG Client 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 transmitted to Premier Heart's datacenter via an encrypted
- Once received at Premier Heart's datacenter the MCG diagnostic system
takes over, running a series of mathematical transformations on the raw ECG
data to identify distinct functional indices.
These indices are compared to our clinically validated database and a numeric
MCG Score assigned to represent the severity of cardiac disease burden observed
during the test.
In addition to the MCG Score the system also provides
a set of differential diagnoses for specific conditions contributing
to the result, giving the treating physician guidelines for additional
evaluation and treatment.
The MCG 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. These reports can provide guidance when referring a
patient to a cardiologist for follow-up testing.
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), exceeding the capabilities of many other techniques
and allowing earlier intervention at stages where coronary artery disease may
be controlled by lifestyle changes or medication.

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 Accurate
a MCG test session and subsequent analysis can typically
be completed within 10 minutes, making it practical
as part of routine care/screening as well as in
urgent care situations for patients with acute
symptoms of cardiac distress.
The high sensitivity and positive/negative predictive
values of MCG analysis also make it viable as a
"rule out" tool.
The MCG 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
Non-Invasive and Stress Free
A MCG test session involves only a surface resting
ECG, and does not share the risks or
contraindications of other diagnostic procedures such
as stress tests, Cardiac MRI or nuclear perfusion
This makes MCG testing practical on a wider range of
patients than many other procedures.
As a non-invasive in-office procedure MCG is
significantly less costly than many other diagnostic
modalities. Initial equipment investments are
significantly lower than CT or MRI angiography
equipment, and per-test costs are comparable to
other resting ECG procedures.
