“…The sensitivity is the ability of the algorithm in detecting the percentage of true beats and positive predictivity +P is the ability of the algorithm in detecting percentage of beat detections which were in reality true beats. 6 A new algorithm was proposed for PVC detection, a vital function for rhythm monitoring in cardiac patients. A transformation of the first difference of digitized ECG is used for the detection of QRS complexes.…”

“…The R location can be obtained by means of various methods, e.g., based on the derivative [5], sliding mean filer, weighted and squared operators of the first derivative [6], detection algorithm of PanTompkins [7]. For PQRST complex detection, there are discrete wavelet transformation based algorithms [8,9], and duration transformation [10].…”

Abstract. The paper deals with process of a cardiological expert system development. A definition of a electrocardiogram is presented. Problems of ECG characteristics determination such as ECG data digitizing is considered. A problem of QRS complex recognition and P and T waves parameters measurement is discussed. A general outline of analysis technique for ECG using wavelet transformation are proposed.

“…Hopefully, our noncausal strategy will also reduce the number of false alarms in situations where an artifact immediately precedes a QRS complex, even for a short eye-closing period. Others claim that by transforming the differenced ECG signal by means of squaring, windowing, and averaging, it will yield a single positive peak for each QRS complex, while suppressing the P and T waves [26].…”
