1. Usefulness of time-axis variable function of digital stethoscope in education on cardiac auscultationWe assessed the application of the time-axis variable function of the digital stethoscope to education on cardiac auscultation. It was suggested that the time-axis variable function could be useful for improving auscultatory ability, and it could be particularly effective in the identification and grasp of the time relation of several sequential heart sounds or murmurs with different components.2. Clinical features of cardiac auscultatory events in outpatients in general internal medicineWe assessed the clinical features of cardiac auscultatory events in outpatients in general internal medicine, and tried to make teaching suggestions for education on cardiac auscultatory skills in primary care medicine. We suggest that the following cardiac ausculatory events should be given educational priority in primary care ; 1) Fourth heart sounds as an extra heart sound. 2) Innocent murmurs : characteristics of innocent murmurs and discrimination from systolic murmurs caused by organic heart disease. 3) Systolic murmurs caused by aortic stenosis or mitral regurgitation. 4) Diastolic high-pitched murmurs caused by aortic regurgitation.3. Education on cardiac auscultation using simulatorAlthough simulation which faithfully reproduces the actuality(high-fidelity simulation) is important, method for comprehensibly displaying by processing a physical phenomenon, such as time-axis variable function of digital stethoscope, could be useful for medical education.
