ABSTRACT
Features the dynamic spectral phonocardiograph (DSP) device that allows doctors to see as well as hear the heartbeats of their patients, a development that could allow them to detect serious cardiac disorders much earlier. Characteristic noises associated with various heart ailments; Ways of detecting defects within the heart; Method for processing the electrical signal from the device's microphone.
