ABSTRACT:
An auscultation system aids a clinician's diagnosis of the heart sounds by visually displaying at least an S1heart sound and an S2heart sound, and ascertaining an onset of at least one of the heart sounds. A corresponding audio representation of the heart sounds can be provided to the clinician. The auscultation system includes a sensor for sensing heart sounds from at least one chest location of the patient and for transducing the heart sounds into electrical signals. The auscultation system also includes a signal processor for selectively filtering the electrical signals thereby highlighting frequency differences of the heart sounds, and further includes a video display for selectively displaying the selectively filtered electrical heart signals. In some embodiments, the auscultation system also displays calipers corresponding to the time domain and the frequency domain of the heart sounds, permitting the clinician to zoom in and out portions of the heart sounds of particular interest and also to take more accurate measurements of these portions of the heart sounds.
