Neural network classification of intracardiac ECG's

Abstract

An artificial neural network has been tested for the classification of cardiac rhythms from intracardiac electrocardiograms (ECGs). It uses as inputs a small number of waveform samples and extracted parameters. The network has been found to perform better than a rate-based scheme similar to those used in commercially available implantable cardioverter-defibrillators in its ability to distinguish normal rhythms from arrhythmias. It shows, in addition, a certain ability to discriminate between a larger number of rhythms: in particular, between sinus tachycardia and slow ventricular tachycardia and between slow and fast ventricular tachycardias.<>
