TLDR
An application of the syntactic method to electrocardiogram (ECG) pattern recognition and parameter measurement is presented and the performance of the resultant system has been evaluated using an annotated standard ECG library.Abstract:
An application of the syntactic method to electrocardiogram (ECG) pattern recognition and parameter measurement is presented. Solutions to the related problems of primitive pattern selection, primitive pattern extraction, linguistic representation, and pattern grammar formulation are given. Attribute grammars are used as the model for the pattern grammar because of their descriptive power, founded upon their ability to handle syntactic as well as semantic information. This approach has been implemented and the performance of the resultant system has been evaluated using an annotated standard ECG library. >read more

Attribute grammar paradigms—a high-level methodology in language implementation
TL;DR: Attribute grammars are a formalism for specifying programming languages as mentioned in this paper, and they have been applied to a great number of systems automatically producing language implementations from their specifications, and representative specification languages are presented with a common example grammar.
Generalized feature extraction for structural pattern recognition in time-series data
TL;DR: The ability of the suite of structure detectors to generate features useful for structural pattern recognition is evaluated by comparing the classification accuracies achieved when using the structure detectors versus commonly-used statistical feature extractors, thus demonstrating that the suiteOf structure detectors effectively performs generalized feature extraction forStructural pattern recognition in time-series data.

TL;DR: The present study demonstrates that to allow an exchange of results and diagnostic criteria between different ECG computer programs, definitions, minimum wave requirements, and measurement procedures urgently need to be standardized.
