Consumer Ultrasounds for Automatic Heart Attack Detection


Need: A way to rapidly detect an myocardial infarction at its earliest stage through an accurate consumer device to notify users and paramedics of abnormal heart activity.

 

Abstract

Every year, half of the 460,000 heart attack deaths in the United States are due to a lack of prompt medical attention. Currently, most consumer-accessible processes which detect oncoming heart attacks simply take too long to be effective solutions. Many biomarkers are released throughout a heart attack, but all biomarkers spike in delayed reactions. Also, current devices are not capable of automatically monitoring the body and reading signs before physical symptoms evolve. There has been a burst of companies which, in integrating the hospital-grade standard of electrocardiography into wearable technologies, have overcome these hurdles. However, they have overpopulated this field and squeezed out room for further innovation. In adapting the success of this wearable trend in the direction of a more novel pursuit, we propose an echocardiogram patch worn over the heart. Our patch detects if a myocardial infarction (MI) is occurring based on periodical dp/dt readings of the mitral regurgitation jet in the left ventricle and connects with a wristband via bluetooth to alert the user and medical authorities in the case of danger. Approximated to be $700, it would provide more speed, accuracy, and awareness than current ECGs for only a slight price increase, thus making it the best market option for consumers. Our prototype represents the basic physical structure of our concept through a 3D printed plastic patch with modeled chips. This summer we concentrated on the design and appearance as the necessary technology was beyond our budget. Future work could bring the concept closer to reality through reiterating the prototyping process for optimal patch materials and a refined circuitry apparatus.
