title: Contribution of the dynamic phonocardiography to the valvular heart disease diagnosis: an expert system study.
abstract: The contribution of pharmacodynamic tests to the diagnostic accuracy of phono-mechanocardiography was tested by means of an expert system, in order to make an objective evaluation. In 198 valvular heart disease patients, the use of dynamic tests significantly improved the rate of diagnostic success, thus confirming the usefulness of dynamic phono-mechanocardiography.
