Learn normal and abnormal heart sounds and murmurs with our audio, video and text lessons. Practice drills, quizzes and an abnormal heart/lung sound reference guide. Each of these resources is described below. We suggest starting with the heart sounds mini-courses along with the related quizzes. It is best to begin with normal sounds, then first, second and third/fourth heart sounds, then adding the several abnormal murmurs.
Course and quiz certificates are available for users enrolled in Auscultation-Essentials or Advanced. Achievement certificates can be printed and are saved to the user's dashboard.
Our auscultation reference guide includes over one hundred heart sounds, both real and simulated.
Our lessons include text, heart/lung sounds, text description, heart sound location indicate, a waveform and cardiac animation.
