Internet digital phonocardiography in clinical settings and in population screening

摘要

A computerized phonocardiographic telemedicine system was developed with the visual interpretation module based on the Morlet wavelet scalograms. Four studies are shown how to use this method: the special diagnostic role of PCG in 287 subjects, the feature extraction capabilities of the Morlet scalogram in 594 patients, the comparison of PCG and echocardiography method in the cardiologic diagnosis of 773 subjects, and the role of PCG in population screening and monitoring in 427 patients. The presented system is the second part - the first was the ECG - of the ongoing development of a complex vital signs measuring wireless system.
