TOPIC: “ELECTROCARDIOGRAM COLLECTION, PATTERN RECOGNITION AND CLASSIFICATION SYSTEM SUPPORTING A CARDIOVASCULAR DISEASE DETECTION AID”

ABSTRACT:
The leading cause of mortality in the United States is heart disease. According to the CDC Division of Vital Statistics, 26% of total death tolls (2,423,712) in 2007 were directly related to heart diseases. Preliminary 2009 data shows that this lethal disease continued to be the main cause of death for 598,607 Americans. Affected patients usually do not comprehend how their disease progress because they are not given the proper training upon hospital discharge to recognize how subtle changes have a large effect on their overall health. There is a financial strain on our healthcare system and it’s important for patients to be knowledgeable in self-care in order to assess and take appropriate action before symptoms become intense.

Current mobile monitoring solutions do not offer the ability to recognize cardiac problems without the use of an outside technician. In support of cardiovascular disease detection aid set forth by Dr. Paul Fortier of UMASS Dartmouth, an attempt is made to perform pattern recognition and classification on a real-time electrocardiogram (EKG). The EKG is detected through the use of the Wavelet Transform and the rhythm is classified using an N-ary tree. The entire software platform is designed and developed in the C language. It’s further loaded and tested on an Atmel microcontroller. Testing results showed that autonomous classifications are possible using a three lead system while the patient is at rest. Further research is required to compensate for muscle noise and motion artifacts, but the proposed classification method serves as a stepping stone towards a fully reliable teaching tool with the potential to serve as a solution to the current cardiovascular healthcare issue.
