Technology Overview
The Multifunction Cardiogram™ (MCG) is a revolutionary new kind of diagnostic tool for measuring the health of a patient’s heart and the impact of ischemia and other problems. MCG™ detects and measures myocardial ischemia with unprecedented accuracy in minutes. The MCG™ unit is a light weight, portable, and durable device that uses diagnostic leads to capture resting ECG data at the point of care by trained technical staff. The test is administered non-invasively, without the use of chemicals or radiation and without causing dangerous stress to the patient. With the help of the MCG™, physicians are able to make much more rapid, objective, and accurate diagnoses of heart diseases.
The MCG™ uses a systems approach to modeling the heart and then comparing these models to a demographically appropriate risk-stratified database of similar patients using 166 indices with that database to aid both in the diagnosis and in predicting patient needs and outcomes.
The MCG™ was created to solve an intractable problem in cardiology: the unacceptable inaccuracies of the EKG and other cardiac-related diagnostic tools and the need for more accurate tools. The inaccuracy of the present diagnostic tools affects both patients with cardiac issues as well as patients whose symptoms may appear to be cardiac-related but are not actually cardiac-derived. An EKG can detect approximately 1/3 of patients with severe coronary artery disease, leaving 2/3 of the patients in danger of dying from their undetected illness. Patients showing signs and symptoms of cardiac-related conditions are often catheterized and have angiograms performed. However, 62 percent of these patients actually have no significant atherosclerosis.
Due to the inability of the current modalities to detect microvascular heart disease, the problem created by inaccurate cardiac diagnostic tools is even more acute for women, leading in part to more women suffering longer term from heart disease than men.
The MCG™ is the culmination of the efforts of two generations of dedicated scientists, mathematicians, engineers, and physicians. It uses rapid, automated, cloud-based, empirically derived digitized clinical databases to give doctors around the world the access to a startlingly accurate diagnostic system.

How it Works
Premier Heart’s MCG™ System represents a radical departure from traditional resting and stress ECG
Where medicine has historically taken a reductionist 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.
Premier Heart’s system consists of three stages:
- First, the medical provider collects 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 transmitted to Premier Heart’s data center via an encrypted internet connection.
- Once received at Premier Heart’s data center, 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 is 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 developing a treatment plan or in referring a patient to a cardiologist for follow-up testing. Sample reports for normal and abnormal patients are available.
