Abstract: Nowadays, one of the most prominent medical problems are cardiac pathologies, and because of this, the instruments created to study the heart are of great importance. Nowadays, with the advance of technology, it is desired that these instruments are simpler to use, smaller, have more features and obtain the best quality of biomedical signals.This article describes the analysis and processing of heart signals, obtained through an accessible electronic prototype that allows generating a presumptive diagnosis of cardiac signals, such as arrhythmias and heart murmurs. The detection of a valvular lesion would help in the identification of abnormalities in the cardiac period. During the experimental phase of this proposal, the sensitivity and specificity results suggest a low-cost option, which makes it accessible as a presumptive diagnostic tool for the detection of valvular heart disease within the health area, especially in times of pandemic by COVID-19 in the city of Cuenca. Cardiac auscultation is important for the prevention of heart diseases; therefore, the contribution of this prototype is intended to be a support tool for the specialist in heart diseases.
