The pulmonary valve can be heard opposite the aortic valve, in the 2nd intercostal space along the edge of the sternum.
Where is the pulmonic valve heard loudest?
When right-sided ejection clicks occur in the presence of a normal pulmonary valve, they are loudest at the upper left sternal border and are usually accompanied by an enlarged pulmonary artery on chest x-ray.
Where do you listen to the pulmonic heart sound?
The pulmonic valve is easy enough to find. It's right across the sternum at the left sternal border. To find the tricuspid valve area, stay on the left side and count down four intercostal spaces. The mitral valve is relatively easy to find if you are used to taking an apical pulse.
Where is S3 best heard?
Also, the S3 sound is heard best at the cardiac apex, whereas a split S2 is best heard at the pulmonic listening post (left upper sternal border). To best hear a S3, the patient should be in the left lateral decubitus position.
Where do you listen for valves?
The pulmonary and aortic valves are both best heard in the 2nd intercostal space, to the left and right respectively. This can make differentiation quite difficult. Sound from the aortic valve is often transmitted to the carotid and can be heard by placing a stethoscope over the carotid bifurcation.

Where is S3 and S4 best heard?
Like S3, the S4 sound is low pitched and best heard at the apex with the patient in the left lateral decubitus position. Below is comparative information for S3 and S4.
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.
Where is S1 and S2 best 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.
Where is S4 best heard?
CLINICAL PEARL: A S4 heart sound is often a sign of diastolic heart failure, and it is rarely a normal finding (unlike a S3). Like S3, the S4 sound is low pitched and best heard at the apex with the patient in the left lateral decubitus position.
Where is the second heart sound best heard?
A2 is best heard at the aortic area (second right intercostal space); P2 is best heard at the pulmonary area. S2 is a high-pitched sound heard best with the diaphragm of the stethoscope.
Where are murmurs heard?
The murmur is heard best between the apex and the left sternal border. It becomes louder with any maneuver that decreases preload or afterload, such as Valsalva or abrupt standing.
Which heart sound is the loudest?
Normally the first (S1) and second (S2) heart sounds are loudest and are audible in all normal animals. S1 is audible at the onset of mechanical systole and occurs in association with closure of the atrioventricular valves.
What is A2 and P2 heart sounds?
The second heart sound (S2) is produced by the closure of the aortic and pulmonic valves. The sound produced by the closure of the aortic valve is termed A2, and the sound produced by the closure of the pulmonic valve is termed P2.
Where is aortic stenosis best heard?
Classically, the aortic stenosis murmur is heard best at the right upper sternal border (where it is harsh and noisy). It radiates to the right supraclavicular area.
What is 4th heart sound?
Definition. The fourth heart sound is a low-pitched sound coincident with late diastolic filling of the ventricle due to atrial contraction. It thus occurs shortly before the first heart sound.
Which heart sound is louder lub or dub?
Identify: S1 – The first heart sound (lub) can be heard the loudest at the mitral area. This sound represents the closure of the mitral and tricuspid valves and is a low pitched, dull sound at the beginning of ventricular systole. S2 – The second heart sound (dub).
What is S3 sound?
Definition. The third heart sound (S3) is a low-frequency, brief vibration occurring in early diastole at the end of the rapid diastolic filling period of the right or left ventricle (Figure 24.1) Synonymous terms include: ventricular gallop, early diastolic gallop, ventricular filling sound, and protodiastolic gallop.
What causes S3?
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 S1 sound?
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). S1 is normally a single sound because mitral and tricuspid valve closure occurs almost simultaneously.
Is S2 louder than S1?
Normally S1 is louder than S2 at the apex. The loudness of the mitral valve closure depends upon 3 things: the degree of valve opening (whether it has had time to passively swing shut because of heart block), the force of ventricular contraction shutting the valve, and.
Is S1 or S2 louder at Erb's point?
At the 2nd L ICS, S2 is much louder than S1. Practice listening over the 2nd L ICS to identify S2 as the louder sound, and then inch slowly along the left sternal border (listen at Erb's point, the tricuspid area and the mitral area at the apex). As you inch along, notice S2 becoming fainter and S1 becoming louder.
Where is the pulmonic valve?
In normal conditions, the pulmonic valve prevents regurgitation of deoxygenated blood from the pulmonary artery back to the right ventricle. It is a semilunar valve with 3 cusps, and it is located anterior, superior, and slightly to the left of the aortic valve.
Why does squatting decrease MVP murmur?
Squatting from a Standing Position
This maneuver will decrease the murmur of HOCM, as the increased left ventricular volume helps displace the hypertrophied interventricular septum, causing less outflow tract obstruction. This maneuver causes the click of MVP to move later in systole.
