Aortic Regurgitation - Moderate
Aortic Regurgitation - Moderate
This is a simulation of Aortic Regurgitation - Moderate taken at Erb's point. Note that S1 is decreased due to premature mitral closure. S2 is single and represents an increased P2. An aortic ejection click follows the mitral component of the first heart sound by 75 milliseconds. A diamond-shaped aortic flow murmur is noted in early systole. A decrescendo, high-pitched, blowing, pan-diastolic murmur is present. The EKG shows evidence of left ventricular hypertrophy. Look at the cardiac animation. It shows an enlarged, hypertrophied left ventricle with normal contractility. A systolic Doppler-plume in the aorta represents a flow murmur while the diastolic left ventricular Doppler-plume represents moderately severe aortic regurgitation.Auscultation Sounds
