Abstract

Heart murmurs are critical indicators of potential cardiovascular conditions yet their detection can often go unnoticed due limitations in equipment and is dependent on clinician experience. Cardiovascular disease remains a leading cause of death worldwide, therefore, early detection of heart murmurs play a crucial role in improving patient outcomes. Many established methods of detection are expensive and often unreliable allowing there to be room for a device which is more cost and result effective. This paper presents the development of a device that attaches onto a regular stethoscope and analyzes auscultatory sounds to diagnose the possibility of a present murmur. Utilizing components such as an electret microphone, a microprocessor, an amplifier, and other various electrical components, a device was constructed and this paper serves to present our process and assembly of the prototype.
