What is the order of heart auscultation?
The standard listening posts (aortic, pulmonic, tricuspid and mitral) apply to both heart sounds and murmurs. 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.
Where do you Auscultate the heart?
Standard sites for auscultation This is where the mitral valve sounds are best auscultated; – Tricuspid area – left fourth intercostal space, just lateral to the sternum. This is where the tricuspid valve sounds are best auscultated; – Pulmonary area – left second intercostal space, just lateral to the sternum.
What are the first and second heart sounds?
- The first heart sound (S1) represents closure of the atrioventricular (mitral and tricuspid) valves as the ventricular pressures exceed atrial pressures at the beginning of systole (point a).
- The second heart sound (S2) represents closure of the semilunar (aortic and pulmonary) valves (point d).
Where are S1 and S2 heard?
Recognizing heart sounds You’ll hear S1 best at the apex of the heart, the left lower sternal border, or the mid-left sternal border. The second heart sound (S2) occurs when the aortic and pulmonic valves, also known as the semilunar valves, close. The closing of the aortic valve, called A2, is loud.

How are auscultatory and palpatory findings of a precordium compared?
A diagram of the major auscultatory and palpatory findings of the precordium should be routinely drawn in the patient’s chart each time the patient’s cardiovascular system is examined (see figure Diagram of physical findings ). With such diagrams, findings from each examination can be compared.
