Recording System For Korotkoff Sound Signals

Abstract

The aim of this study is to help to improve new diagnosis methods for cardiovascular disease by designing a computer program and a hardware which realizes the recording of Korotkoff sounds produced during the measurement of blood pressure and basic analysis process. Korotkoff sounds have been traditionally used to measure blood pressure noninvasively by employing the auscultatory method. The recording system developed in this study can be used to produce a large database by recording some important information such as weight, age, and disease name in addition to Korotkoff sounds. Basic analysis processes like filtering and finding frequency component of recorded data is accomplished by means of the designed software. Thus, the necessity of using different computer programs for analyzing and recording data has been eliminated
