Where is aortic valve auscultated




















The intensity of the murmur typically increases as disease progresses; however, when heart failure develops and cardiac output declines, the murmur becomes softer. Thus, the intensity of the murmur is not a good indicator of disease severity. Enlarge Auscultation at the cardiac apex may reveal a murmur that may sound midsystolic or holosystolic and may mimic the murmur of mitral regurgitation.

However, this is commonly the result of radiation of the murmur of aortic stenosis to the apex rather than coexistent mitral regurgitation. This finding is referred to as "Gallavardin dissociation. At times, the murmur of hypertrophic cardiomyopathy can also mimic the murmur of aortic stenosis. The Valsalva maneuver decreases the murmur of aortic stenosis while it increases the murmur of hypertrophic cardiomyopathy. BMC Med Educ. Hi, I recently had a limb lead test for my arms and legs. Leads 2 and 3 were both healthy and normal but lead 1 had a regularity.

It was a slow weak signal. Naturally I'm going to be talking with my Disclaimer: This article is for information only and should not be used for the diagnosis or treatment of medical conditions.

Introduction Auscultation of the heart is not synonymous with examination of the heart. Mechanism of sounds Heart sounds normal or pathological are caused by turbulent blood flow.

Position the patient at degrees. Aortic area Place the diaphragm of the stethoscope at the 2 nd intercostal space, right sternal edge. This is the anatomical landmark for the aortic valve. Listen for at least 5 sec for the second heart sound, which represents the aortic valve closing.

Pulmonic area Place the diaphragm of the stethoscope at the 2 nd intercostal space, left sternal edge. This is the anatomical landmark for the pulmonary valve.

Listen for at least 5 sec for the second heart sound, which represents the pulmonary valve closing. Tricuspid area Place the diaphragm of the stethoscope at the 4 th - 5 th intercostal space, left sternal edge.

This is the anatomical landmark for the tricuspid valve. Listen for at least 5 sec for the first heart sound, which represents the tricuspid valve closing. Mitral area Place the diaphragm of the stethoscope at the 5 th intercostal space, mid-clavicular line same area as the apex beat. This is the anatomical landmark for the mitral valve. Listen for at least 5 sec for the first heart sound, which represents the mitral valve closing. Other auscultation areas: Auscultation of the lungs and major arteries also provides essential information of the function of the cardiovascular system.

Auscultate with the diaphragm of the stethoscope at the bases of the lungs. Listen for any crepitations or crackles, which indicate fluid in the lungs pulmonary edema , a sign of heart failure.

It should be placed very lightly against the precordium otherwise it will, effectively, be a diaphragm Scott and MacInnes, ; Cox and Roper, According to Scott and MacInnes and Cox and Roper , the standard sites for auscultation of the heart are Fig 3 :. This is where the mitral valve sounds are best auscultated;. This is where the tricuspid valve sounds are best auscultated;. This is the area where sounds from the pulmonary valve are best auscultated;. This is where the aortic valve sounds are best auscultated.

Recommendations for auscultation of the heart vary. The following procedure is based on Cox and Roper :. To assist identification of these heart sounds, it may be necessary to palpate the carotid pulse at the same time as this will coincide with the first heart sound Ford et al, Fig 5 ;. This is the best position and method to auscultate the low-pitched mid-diastolic murmur of mitral stenosis.
