โœฆ Synopsis

A syntactic algorithm for filtering ECG waveforms is described in this paper. The algorithm can also be used for reducing the number of points representing the digitized ECG waveform. The formalism of attribute grammars is used to describe the algorithm which has been implemented with a program that parses the ECG waveforms in linear time. Two parameters are utilized for defining the size of the pulses to be considered as noise and this increases the flexibility of the algorithm. Application examples as well as the description of the experimental setup which was used is also given.

A simple method is developed for the delineation of a given electrocardiogram (ECG) signal into its component waves. The properties of discrete cosine transform (DCT) are exploited for the purpose. The transformed signal is convolved with appropriate filters and the component waves are obtained by c
