LabVIEW based ECG signal acquisition and analysis

摘要

This paper presents a LabVIEW based system of acquisition, processing and analysis of ECG (electrocardiogram) signals. Biomedical signal acquisition has made great advances in recent years due to the introduction of modern hardware and software technologies. Computer based signal processing systems are becoming an efficient approach for acquisition and analyzing of such signals. In our implementation an AD8232 integrated signal conditioning front end of Analog Devices is used for measurement and preprocessing of the ECG signals. Battery powered data acquisition system, which avoids 50Hz noise and allows for safety measurement without additional isolation is employed. LabVIEW Biomedical Toolkit time-domain analysis is applied to study heart rate variability together with additional parameters.
