Heart Murmurs and Heart Sounds: Visual Explanation for Students

In this video I help you understand heart murmurs and heart sound using a simple explanation with illustrations and animations. We cover the heart sounds S1, S2, S3 and S4, mitral stenosis, mitral regurgitation, aortic stenosis and aortic regurgitation. We also discuss the features of murmurs, grades of murmurs and how dilatation and hypertrophy are linked to valve pathology.
