Can a software-based medical instrument for color spectrographic analysis of the phonocardiogram successfully obtain heart sound spectra in human subjects?
A novel software-based medical instrument for color spectrographic analysis of the phonocardiogram demonstrated feasibility in obtaining heart sound spectra, suggesting potential as a future noninvasive cardiac monitoring technology.
Should not yet change practice; leaves open potential for noninvasive cardiac monitoring applications.
After briefly reviewing the state of the art in phonocardiography, this report describes the design and preliminary evaluation of a software-based medical instrument for spectrographic heart sound monitoring. The system uses an ordinary personal computer, an audio amplifier, and an electret microphone that attaches to a precordial stethoscope. In a preliminary clinical evaluation involving 5 subjects, heart sound spectra were easily obtained. We suggest that color spectrographic analysis of the phonocardiogram may become a future noninvasive cardiac monitoring technology.
