[Testing a computer program for use in cardiology].
An already published method for automatic processing of a single ECG signal was tested on the base of a data set of a foreign clinic. The yielded results of the P-wave recognition (recognition ratio 87.1% with a failure ratio of 6.0%) confirm fully its reliability reported before. This paper gives a valuation of the method from the clinical point of view by reference to literature considering technical questions. The most important application of this method is the ECG processing under pressure requiring precise time - measuring, classification of separate patterns and recognition even of non-marked parts of the signal course as P-waves, ST-segments and T-waves. Methodical adaption of the method to the special range of application is necessary in all cases. General questions for prospective evaluation of a given automatic recognition system by physicians are discussed briefly.
