Phonocardiogram: evaluate and construction
Abstract
This paper presents the development of a test to monitor heart rate (HR) which is characterized by low cost material expended in its production. In order to verify the applicability of the phonocardiogram (FCG), it was compared with a HR monitor from Polar Inc (Finland) model RS 800 Cx HR in nine (9) subjects (4 males and 5 females). The measures were made in the sitting and supine position (Zuttin, R. S., Moreno, M. A., César, M. C., Martins, L. E. B., Catai, A. M., & Silva, E.,2008) during 5 minutes (Vanderlei, L.C.M., Silva, R.A., Pastre, C.M., Azevedo, F.M. & Godoy, M.F., 2008). A correlation of r = 0.982 to supine position and of r = 0.794 to sitting position was obtained, both with p <0.05. The building of this instrument is suggested to teaching and learning of the HR monitoring, and its importance is demonstrated as a method for understanding the autorregularion and the internal rhythms of body.
