Electrocardiogram Classification Using Reservoir Computing With Logistic Regression

An adapted state-of-the-art method of processing information known as Reservoir Computing is used to show its utility on the open and time-consuming problem of heartbeat classification. The MIT-BIH arrhythmia database is used following the guidelines of the Association for the Advancement of Medical Instrumentation. Our approach requires a computationally inexpensive preprocessing of the electrocardiographic signal leading to a fast algorithm and approaching a real-time classification solution. Our multiclass classification results indicate an average specificity of 97.75% with an average accuracy of 98.43%. Sensitivity and positive predicted value show an average of 84.83% and 88.75%, respectively, what makes our approach significant for its use in a clinical context.This work was supported by the grant FIS2012-30634 (Intense@cosyp) from MINECO (Spain) and FEDER and Grups Competitius, Comunitat Autonoma de les Illes Balears, Spain.Peer Reviewe
