چکیده
Different methods have been projected and used for ECG feature extraction with a substantial percentage of precise detection. However, the problem remains exposed especially regarding higher detection precision in noisy ECG. In this work, we have developed an algorithm based using LabVIEW 8.5. LabVIEW (Laboratory Virtual Instrument Engineering Workbench) is a graphical user interface design language that uses icons in its place of lines of text to generate programs. Firstly, it detects the ECG signal from the ECG amplifier system and preprocesses (denoises) the signal to eradicate the noise from the ECG signal. Then it detects QRS complex and their onsets and offsets. LabVIEW and the related toolkits, advanced signal processing toolkit are used to build the graphical program for both the stages. The algorithm is evaluated with ECG data collected from normal volunteers, recorded at a sampling rate of 512Hz using NI USB 6008. Finally, a program was designed to send the report of the subject via email to his/her email id. Thus this work aims to develop a compact ECG analyzing the device. Key word: Data Acquisition, ECG, Feature Extraction, LabVIEW, Mobile Interface.
