CARDIAC - HEART - SOUNDS
The heart sounds are the noises (sound) generated by the beating heart and the resultant flow of blood through it. This is also called a Heartbeat. In cardiac auscultation, an examiner may use a stethoscope to listen for these unique and distinct sounds that provide important auditory data regarding the condition of the heart to a trained observer. In healthy adults, there are two normal heart sounds often described as a lub and a dub (or dup), that occur in sequence with each heart beat. These are the first heart sound (S1) and second heart sound (S2), produced by the closing of the AV valves and semilunar valves respectively. In addition to these normal sounds, a variety of other sounds may be present including heart murmurs, adventitious sounds, and gallop rhythms S3 and S4. Heart murmurs are generated by turbulent flow of blood, which may occur inside or outside the heart. Murmurs may be physiological (benign) or pathological (abnormal). Abnormal murmurs can be caused by stenosis restricting the opening of a heart valve, resulting

The Physiological Origins of Heart Sounds and Murmurs
This is the one and only multimediaprogram that integrates actual heart sounds with dynamic images of both normal and diseased hearts.
Includes ultrasound and X-ray motion picture images, graphic hemodynamic recordings, animated diagrams, gross pathology, and text to help physicians and other health professionals better recognize classical heart sounds and murmurs.
You will be truly amazed at how these difficult-to-visualize concepts become suddenly clear while you watch, listen and learn.
