  • Apparatus and method for discriminating between cardiac rhythms on the basis of their morphology using a neural network
    Patent number: 5542430
    Abstract: An apparatus and a method are provided for coupling to a patient's heart for discriminating between tachycardias of physiological origin, and those of pathological origin having similar rates; and also for discriminating amongst those of pathological origin having similar rates. The apparatus includes transducers and/or sensing electrodes in either or both the atrium and/or ventricle. Also included are signal processing elements for determining the times of atrial and ventricular events and for extracting morphological features from the waveforms, and a neural network for classifying the heart rhythm. The method includes a step of discriminating between different types of heart rhythms having overlapping rates.
