In this work we want to study and implement some methods to analyze the heart rate
The first part consists in use spectral analysis methods, Time-Frequency representations
and component separation to detect and isolate cardiac beats and their components in an
electrocardiogram signal. We describe algorithm for beat isolation as well as event and
fiducial points detection that constitute them.
In the second part we determinate the heart rate variability and it’s relation to the
temporal and spectral variations of the characteristics that were found in the previous
The main objective of this study is to comprehend the phenomenon that characterizes
the heart beat variation of a patient
