Implementación de un sistema de obtención de frecuencia cardíaca a partir del seismocardiograma.

Abstract

One of the areas of telecommunications related to biomedicine is the processing of biomedical signals, whose work is much approached by researchers. The development of non-invasive and non-restrictive methods for cardiac monitoring is a topic of growing interest in its application to home monitoring of the elderly. Recent studies show that the signal from the seismocardiogram (SCG) can be used for these purposes. The development of sensitive and inexpensive accelerometers, available in cell phones, facilitates the acquisition of that signal. In this work, a method to det ermine the instantaneous heart rate (FCI) was implemented and evaluated by the digital processing of the SCG using the Hilbert Transform for this purpose. To evaluate the method, SCG and electrocardiogram (ECG) signals were acquired simultaneously in healthy subjects from the CEBS database on the Internet site www.physionet.org, of internationally recognized quality.
