Where do you Auscultate for cardiac assessment?
– Pulmonary area – left second intercostal space, just lateral to the sternum. This is the area where sounds from the pulmonary valve are best auscultated; – Aortic area – right second intercostal space, just lateral to the sternum. This is where the aortic valve sounds are best auscultated.
What are the 4 heart sounds?

What does auscultation of the heart reveal?
Cardiac auscultation may detect an irregular rhythm or premature beats. Stress testing, usually with imaging (e.g., stress echocardiography or stress thallium and echocardiography) can demonstrate the presence of CAD, LV dysfunction, or valvular heart disease.
How is auscultation performed?
Auscultation is usually done using a tool called a stethoscope. Health care providers routinely listen to a person’s lungs, heart, and intestines to evaluate these things about the sounds: Frequency.
Why do we Auscultate the heart?
The purpose of auscultation of the heart is to characterize heart sounds and murmurs. (See “Examination of the precordial pulsation” and “Examination of the arterial pulse” and “Examination of the jugular venous pulse”.)
What causes the 3rd heart sound?
Third Heart Sound S3 Results from increased atrial pressure leading to increased flow rates, as seen in congestive heart failure, which is the most common cause of a S3. Associated dilated cardiomyopathy with dilated ventricles also contribute to the sound.
What is the purpose of auscultation?
Auscultation is the term for listening to the internal sounds of the body, usually using a stethoscope. Auscultation is performed for the purposes of examining the circulatory system and respiratory system (heart sounds and breath sounds), as well as the gastrointestinal system (bowel sounds).
Why is auscultation used?
Which part of stethoscope hears heart sounds?
