Digital Subtraction Phonocardiography (DSP) applied to the detection and characterization of heart murmurs
Abstract Background During the Dab Rigs cardiac cycle, the heart normally produces repeatable physiological sounds.However, under pathologic conditions, such as with heart valve stenosis or a ventricular septal defect, blood flow turbulence leads to the production of additional sounds, called murmurs.Murmurs are random in nature, while the underlyi
