Heart sound and ECG signal analysis and detection system based on LabVIEW

Digitized auscultation can promote the problem of heart sound and ECG detection. The main research of this paper the heart sound and ECG signal detection and analysis system. First, the sensor is used to collect the human heart sound and ECG signal on the platform of virtual instrument LabVIEW. And send it to the upper computer of LabVIEW via the front-end circuit adjustment after the module transformation. Then, synchronous collection of heart sound and ECG signal is digitized and simple filtered processing. Meanwhile the data display, storage and playback waveform function are also realized by LabVIEW. Finally, this paper realize the segmentation and positioning of the heart sound and ECG signal based on LabVIEW and Matlab programming. The collection and analysis system performance is reliable, and the module is practical and easy to operate. The normalization of collection provides convenience and reference for the analysis and recognition of the follow-up heart sound, ECG data building and pathology signal.
