Heart Sounds

Multimedia reference guides and courses

Reference Guide

Our cardiac auscultation reference guide includes over a hundred cardiac sounds. These sounds include both recorded patient heart murmurs as well as simulated sounds. The reference guide is organized by auscultation location. The guide also includes listening tips and phonocardiograms.

Reference Guide

Courses

Learn heart murmurs and other heart sounds using these courses. Over 60 lessons present systolic and diastolic murmurs, third (S3) and fourth (S4) heart sounds and congenital conditions. Each lesson includes audio, text, phonocardiogram and cardiac animation. Use the Quick Links panel to select a course.

We recommend that beginning student start with our Introduction to Heart Murmur page, then take the Normal Heart Sounds course and progress down the list of additional courses, at least through the Diastolic Murmurs course. Courses typically take 15-20 minutes.

Heart Murmur Introduction

Auscultation Repetition Training

For some learners, auscultation repetition training is a useful complement to our courses. We provide repetition training along with a dynamic phonocardiogram for helping users memorize each sound.

Pulmonary Arterial Hypertension

Learn to recognize abnormal heart sounds related to pulmonary arterial hypertension. This is a new course, developed by Dr Jon Keroes and David Lieberman.

Pulmonary Arterial Hypertension

Carotid Bruit

Recently developed, this course extends auscultation skills by a series of case studies related to carotid artery disease. Using our carotid artery exam simulator, you will be to identify carotid bruit, which is caused by turbulent blood flow in an artery which supplies blood to the brain.
