项目摘要

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.

1.数字听诊器时间轴可变功能在心脏听诊教学中的应用探讨数字听诊器时间轴可变功能在心脏听诊教学中的应用。提示时间轴可变函数对提高听诊能力有一定的帮助，特别是对识别和把握几个不同成分的连续心音或杂音的时间关系有很好的效果.普通内科门诊患者心脏听诊事件的临床特点我们评估了普通内科门诊患者心脏听诊事件的临床特点，并试图为基层医疗中心脏听诊技能的教育提出教学建议。我们建议在初级保健中应优先考虑以下心脏听诊事件：1）第四心音作为额外的心音。2)无害杂音：无害杂音的特征及与器质性心脏病引起的收缩期杂音的鉴别。3)主动脉瓣狭窄或二尖瓣返流引起的同步杂音。4)主动脉瓣关闭不全引起的舒张期高音调杂音。使用模拟器进行心脏听诊的教育虽然忠实地再现现实的模拟（高保真模拟）很重要，但通过处理物理现象（如数字听诊器的时间轴可变功能）来理解显示的方法可能对医学教育有用。
