Where do you Auscultate mitral valve?

Standard sites for auscultation – Mitral area – left fifth intercostal space, mid-clavicular line. This is where the mitral valve sounds are best auscultated; – Tricuspid area – left fourth intercostal space, just lateral to the sternum.

What is the best location to Auscultate the mitral valve of the heart?

For example, the S1 heart sound — consisting of mitral and tricuspid valve closure — is best heard at the tricuspid (left lower sternal border) and mitral (cardiac apex) listening posts. Timing: The timing can be described as during early, mid or late systole or early, mid or late diastole.

What is the mitral area?

Area of the chest wall over the apex of the heart where mitral valve sounds are heard best (usually between intercostal spaces 5–6 to the left of the midclavicular line).

Where is S2 heard?

Splitting best heard in the 2nd left intercostal space, close to the sternal border. Second heart sounds are best heard when patients are semi-recumbent (30-40 degrees upright) and in quiet inspiration.

How do you perform a heart auscultation?

Listen over the aortic valve area with the diaphragm of the stethoscope. This is located in the second right intercostal space, at the right sternal border (Figure 2). When listening over each of the valve areas with the diaphragm, identify S1 and S2, and note the pitch and intensity of the heart sounds heard.

Where is mitral valve situated?

mitral valve: located between the left atrium and the left ventricle.

What are the 3rd and 4th heart sounds?

Third & Fourth Heart Sounds A triple rhythm in diastole is called a gallop and results from the presence of a S3, S4 or both. Description: Both sounds are low frequency and thus best heard with the bell of the stethoscope.

What are S3 sounds?

The third heart sound (S3), also known as the “ventricular gallop,” occurs just after S2 when the mitral valve opens, allowing passive filling of the left ventricle. The S3 sound is actually produced by the large amount of blood striking a very compliant left ventricle.

Where does auscultation take place in the heart?

When performing a cardiac exam, auscultation should be performed with the diaphragm and then repeated with the bell. The locations of auscultation center around the heart valves. The aortic, pulmonic, tricuspid, and mitral valves are four of the five points of auscultation.

Is the second heart sound normal in auscultation?

This is an auscultation example of moderate regurgitation of both the aortic and mitral valves. The first heart sound is minimally decreased due to minimal closure of the mitral valve leaflets in early systole. The second heart sound is normal.

Is the first heart sound normal with mitral regurgitation?

The first heart sound is minimally decreased due to minimal closure of the mitral valve leaflets in early systole. The second heart sound is normal. There is a rectangular murmur which takes up most of systole and a decrescendo murmur which takes up most of diastole. Both murmurs are of moderate intensity.

What causes a heart murmur during auscultation?

Murmurs are cause by turbulent blood flow. They are described in relation to the following heart sounds: While auscultating, the radial or brachial pulse should be palpated as they indicate systole. Any murmur between S1 and S2 is named systolic as it occurs during the systolic phase of cardiac contraction.
