Abstract:
Objective To develop LabVIEW-based digital PCG analyzer. Methods A kind of Digital PCG analyzer based on LabVIEW was designed. It included a heart sound sensor, an analog filtering circuit and amplifying circuit, an AD converter, a digital data transferring model and a software for PCG analyzing. Meanwhile, a kind of 3-lead ECG sampling circuit and a display model in LabVIEW were designed as a reference signal for PCG. distinction. Results This digital PCG analyzer had the functions of heart sound sampling from body surface, PCG real-time displaying on the software, spectrum analyzing for the PCG data and PCG database managing. Conclusion This kind of digital PCG analyzer based on LabVIEW can be used for assistant diagnosis of cardiac Arrhythmia and cardiac abnormal noise, and as a teaching tool for clinical auscultation.
