Visual spectrum coding of heart sounds attributes

Cardiovascular diseases encompassing coronary artery disease, hypertension, cardiomyopathy, cardiac stenosis, arrhythmia, and other are often accompanied by peculiar acoustic events which can be reflected in auscultatory observations and recordings. A quantitative documentation of these events may add in diagnostic assessment of patient conditions and complement monitoring of the therapeutic process. Therefore, a developed technique of heart sound signals audio spectrum conversion to visual frequencies provides a clinically applicable tool for documentation of the acoustic signatures of heart sounds and their quantitative assessment.
