Heart Sounds Audio Introduction
This website provides several types of learning resources for
heart sounds audio and murmurs
. We offer courses, reference guides and repetition training. Each of these resources is described below. If you are a new visitor, we generally recommend starting with the
heart sounds audio
courses, moving from the normal cardiac sounds course through murmurs and then congenital abnormalities.
Heart Sounds Audio Reference Guide
Our reference guide includes over a hundred cardiac sounds audio, both real and simulated. Use these buttons to view sounds by auscultation area.
Heart Sounds Audio Lessons
Learn cardiac auscultation by taking our courses. These courses cover abnormal heart sounds including heart murmurs, third (S3) and fourth (S4) heart sounds and congenital conditions. Learn these sounds by selecting a topic from the table of contents below. If you are new to cardiac auscultation, we recommend this one page
