Extracting Samples as Text from ECG Strips for ECG Analysis Purpose

摘要

The paper presents a work of conversion of ECG signal from ECG strips/papers to samples as text which is analogous to the standard MIT-BIH Normal Sinus Rhythm/Arrhythmia database. ECG strips are scanned and then using MATLAB, the data is obtained for the ECG taken from Indian patients. The parameters like Heart rate, PR interval, QRS duration, QT interval and RR interval are compared. The result shows 99% accuracy in the data obtained by this method. The process of extraction of ECG data is also validated for Normal Sinus Rhythm/Arrhythmia from MIT-BIH database. The correlation obtained is nearly 98%. Thus the method is useful for automatic analysis of ECGs from ECG strips at rural areas also.
