For heart sounds listen to the synthetic sound while reviewing this lesson.
This is a simulation of Aortic Stenosis - Severe taken at the second right intercostal space.
A late peaking, diamond-shaped, systolic murmur is present. The EKG shows evidence of LVH. Look at the cardiac animation. It shows left ventricular hypertrophy and a thickened and minimally mobile aortic valve. Note the Doppler-plume, which represents systolic turbulent flow across a stenotic aortic valve.
- S1 is normal.
- S2P is increased suggesting an elevated left sided filling pressure.
- An S4 gallop indicates the presence of a non-compliant left ventricle.
