Research project: Architecture of Neural networks for arrhythmia detection
This project describes the development of a detection system for the QRS complexity present in the electrocardiogram. The capture of electrocardiogram signal was achieved through electrodes with the help of an acquisition card. On the part of the signal processing and the graphical user interface were made by programming in Python. The technique used to detect the R peaks was the use of the Hilbert transform and adaptive thresholds [2].

QRSComplex The QRS complex is of great importance for the diagnosis of cardiac anomalies, which is why new algorithms and mathematical models are sought for its detection. In addition, the monitoring of the ECG signal in people who present these problems, through conventional electrocardiograms, is limited because the person is wired to the device and lacks portability, preventing information from being obtained when the person is doing daily activities.

Connection This project presents a data acquisition system for the R peak detection in electrocardiograms. R wave is one of the most important sections of the QRS complex, which has an essential role in diagnosis of heart rhythm irregularities. This paper employs Hilbert transform and adaptive threshold technique for the detection of R peak.

The performance of the system was tested using standard ECG waveform records from the MIT-BIH arrhythmia database. In addition, tests were carried out using the sensors for
real-time data processing [2].
