Abstract

An intelligent tachycardia diagnosis system assists the clinicians in discriminating normal and various tachycardia classes of heartbeats generally in the life-threatening conditions. This paper proposes, a methodology to classify multiclass tachycardia class using Electrocardiogram (ECG) signal. In this work, tachycardia classes are marked using nonlinear transform domain method Empirical Mode Decomposition (EMD). Using which tachycardia beats namely Atrial Flutter (AFL), Atrial Fibrillation (A-Fib), Ventricular Fibrillation (V-Fib) and Normal Sinus Rhythm (NSR) is discriminated. Independent Component Analysis (ICA) is applied on the patterns for dimensionality reduction and ten-fold cross validation is executed during the classifier development. Performance of diagnosis is compared individually using these three classifiers viz. Decision Tree (DT), Rotation Forest (ROF) and Random Forest (RAF) through Cohen's kappa statistic (κ), overall accuracy (%) and class specific accuracy (%). In current study, altogether 3858 ECG beats, belonging to four classes of tachycardia are used. The results obtained presents EMD coefficients clinical significance (p<0.0001). Besides, using RAF ensemble classifier we have achieved with an accuracy of 91.21% in diagnosis of tachycardia beats. The proposed approach can be used in the cardiac portable devices such as defibrillators and telemonitoring applications.
