Detección de picos R en ECGs y su aplicación en serie de tiempos RR

Abstract

The Heart Rate Variability (HRV) describes variations between consecutive heartbeats. Stress, certain heart diseases and other pathological conditions affect HRV. That is the reason why so much emphasis has now been placed on the analysis of the so called "RR variability" (where R is the point corresponding to the peak of the QRS complex of the ECG wave). This variability is recorded in a series of times which we proceed to apply different tools that allow us to extract information from the cardiac behavior. In this paper we introduce a simple technique that allows us to obtain the series of times of RR intervals from the "raw" data of an electrocardiographic output and compare the results with the global records of PhysioBank, which is a database that contains more than 36,000 recordings of digitized physiological signals organized as collections of free availability.
