Abstract

A device that calculates a sudden cardiac death score based on acquired patient data. A system and method that combines independent indications of sudden cardiac death to predict sudden cardiac death. The system can include various cardiology test systems interconnected to a sudden cardiac death prediction system.

Claims

acquiring patient data from a plurality of medical equipment databases; and

analyzing the patient data to determine a sudden cardiac death risk score.

2. The method of claim 1 and further comprising generating multiple independent indications of sudden cardiac death based on the patient data acquired from the plurality of medical equipment databases.

3. The method of claim 1 wherein the patient data includes image data, and further comprising comparing the image data to stored image patterns to determine an image measurement.

4. The method of claim 3 and further comprising comparing the image measurements to a range to determine an image correlation.

5. The method of claim 1 wherein the patient data includes electrocardiogram data, and further comprising comparing the electrocardiogram data to stored electrocardiogram patterns to determine an electrocardiogram measurement.

6. The method of claim 5 and further comprising comparing the electrocardiogram measurement to a range to determine an electrocardiogram correlation.

7. The method of claim 1 and further comprising determining a mathematical measurement based on a parameter value.
