Application of Virtual Instrumentation for Transmitting and Processing ECG Signals

The paper aims to emphasize the possibilities offered by Virtual Instrumentation (LabVIEW) in the field of biomedical engineering. Thus, it proposes a low cost and flexible wireless transmission (between two equipments) and ECG signals processing architecture. Since during acquisition the signal may be corrupted by noise, in the first stage of the application the signal is filtered by implementing a designed mean averaged filter, followed by a Butterworth filter. The second stage of the application is represented by the infrared transmission of the signal between two infrared “in range” compatible devices. Finally, for an accurate R-peak detection, the Pan-Tomkins algorithm was implemented.
