Patent References 3755783 3829766 Apparatus for pattern recognition of ECG signals for detecting fibrillation Trainable neural network Method and system for wavefront reconstruction Method and apparatus for detecting a sequence of abnormal events in an electrical signal, particularly in the depolarization signal of a heart Arrhythmia control system employing arrhythmia recognition algorithm Waveform analysis apparatus and method using neural network techniques Patent #: 5092343 InventorsAssigneeApplicationNo. 947337 filed on 09/18/1992US Classes:600/515, Detecting arrhythmia128/925, Neural network706/20, Classification or recognition706/924MedicalExaminersPrimary: Kamm, William E.Attorney, Agent or FirmInternational ClassA61B 005/045.2Foreign Application Priority Data1991-09-20 AUAbstractThe application is directed to a method for automatically classifying intracardiac electrograms, and a system for performing the method. In a further aspect, it concerns an implantable cardioverter defibrillator which incorporates the system and uses the method to monitor cardiac activity and deliver appropriate treatment. The method uses a combination of timing analysis and pattern matching using a neural network in order to correctly classify the electrograms. This technique allows both changes in rate and morphology to be taken into account. | |
