SignUp Patient Normal Speed play pause Patient Half Speed play pause Simulated Full Speed play pause Lesson For heart sounds listen to the synthetic sound while reviewing this lesson. This is an example of Ebstein's Anomaly as heard at the tricuspid area.The first heart sound is increased due to thickening of the tricuspid valve leaflets.The second heart sound is normal.A rectangular murmur of tricuspid regurgitation fills all of systole.An opening snap occurs 100 milliseconds into diastole followed by a decrescendo-crescendo murmur of mitral stenosis.These findings are all a manifestation of downward displacement of the tricuspid valve into the right ventricleIn the anatomy tab you can see the enlarged right atrium and the small right ventricle. The upward plume from the right ventricle to the right atrium represents the systolic murmur.The downward plume from the right atrium to the right ventricle represents the diastolic murmur.This abnormality is congenital in nature. The waveform(s) seen above are a chart of sound amplitude (loudness) on the vertical axis against time on the horizontal axis. Listening Tips A summary of the key aspects of this heart or lung sound. S1: Increased intensity. Possible splitting. Systole: Rectangular.S2: Possible splitting.. Diastole: Opening snap followed by decrescendo-crescendo murmur. Auscultation Method The recommended patient position is supine For this sound, use stethoscope's diaphragm The recommended auscultation position for the stethoscope is tricuspid Relevant Courses If you wish to review a complete mobile concerning Ebstein's Anomaly Auscultation Reference and related heart sounds, the modules(s) listed below may be useful. Each lesson includes text that explains the auscultatory sound and its clinical significance. The lesson also includes an audio track for playback. A waveform provides a great way to visualize the sounds. Finally, we also include an animation video. For heart sounds, the video illustrates heart muscle and valve movements along with blood flow. For lung sounds, the primary source of the sounds can be seen. Each module also includes a quiz.
