Heart Sounds and Murmurs
Multimedia reference guides and courses


Learn heart murmurs and other abnormal 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 students start with our Introduction to Heart Murmur page.

Heart Murmur Introduction

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. Our Auscultation in Primary Care followed by Basic Lung Sounds is another excellent learning pathway.

Reference Guide

This reference guide for heart sounds includes over a hundred audio recordings with descriptions. Audio tracks include both recorded patient heart murmurs and simulated heart murmurs. This list of sounds can be filtered by auscultation position.

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 Hypertension

Carotid Bruit

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.

Pediatrics - When To Refer

Pediatric murmurs can be innocent or require referral. This course aims to improve your auscultation skills and decisions-making for pediatric heart murmurs. Offered by our sister website, EasyAuscultation.

Heart Sound Drills

This module is designed to help intermediate learners to efficiently recognize heart sound splits as well as s3 and s4. The drill features in this software help students be confident when auscultating the heart. Individualized progress tracking is available.

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.
