Análise de sons cardíacos de cães de pequeno porte através de estetoscópio eletrônico

Abstract

The electronic stethoscope is a listening device that allows you to record and analyze the sound during the consultation or at another time. Currently, there is sufficient evidence to prove the advantages of the instrument compared to the traditional model such as graphic recording of sound and reduction of the subjectivity of acoustic auscultation interpretation. With the purpose of studying a method that analysis of cardiac sounds with the electronic stethoscope, this research aims to present how the analysis of cardiac sounds contributes to the diagnosis of cardiac disease in small dogs, with the benefit of graphical and numerical visualization of the beep. For this, a total of 56 animals were submitted to acoustic and electronic auscultation, as well as the numerical analysis of the duration of the cardiac cycle, relative time of systole and relative amplitude. The data obtained through the acoustic auscultation were correlated with the electronic auscultation and analyzed. The results showed it is possible to obtain the healthy animals characteristics. However, through the parameters analyzed, it is not possible to identify a animals with cardiac murmur characteristic.
