What does extra heart sounds indicate?
An S3 gallop or “third heart sound” is a sound that occurs after the diastole S2 “dub” sound. In young athletes or pregnant women, it’s likely to be harmless. In older adults, it may indicate heart disease. An S4 gallop is an extra sound before the S1 systole “lub” sound.
What is a cause of the extra heart sounds known as 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 causes systolic click?
Systolic ejection clicks occur in early systole and may result from either the abrupt opening of the semilunar valves or the rapid distention of the proximal aorta or pulmonary artery at the onset of ejection. Systolic ejection clicks may be aortic or pulmonary in origin.
What are the 3rd and 4th heart sounds?
The third and fourth heart sound (S3 and S4) are two abnormal heart sound components which are proved to be indicators of heart failure during diastolic period.
What are the different types of heart sounds?
In a healthy adult, the heart makes two sounds, commonly described as ‘lub’ and ‘dub. ‘ The third and fourth sounds may be heard in some healthy people, but can indicate impairment of the heart function. S1 and S2 are high-pitched and S3 and S4 are low-pitched sounds.
Which extra heart sounds may occur in early diastole?
The present case had S4 and additional heart sounds during early diastole on auscultation. The differential diagnoses for additional sounds during diastole include split S2, S3, mitral opening sound, and pericardial knock sound.
What is S3 heart sound indicative?
The third heart sound is a normal finding in children and young adults, in which groups, the sound is indicative of a supple ventricle that can undergo normal rapid expansion in early diastole. Conversely, when heard in a middle-aged or older adult, the S3 sound is often a sign of disease.
Which of the following is an extra or unexpected heart sound?
The “dub” sound occurs when the heart’s two other valves shut, after blood is pumped out of the heart. A heart murmur is an extra, unexpected sound that doctors hear with a stethoscope when they’re listening to the blood move through the heart.

If you have atrial fibrillation, the top two chambers of your heart contract too quickly, and in an irregular pattern.
What kind of sounds do you hear in Your Heart?
The primary Heart Sounds are S-1 and S-2. Any pathology in the Heart causes additional sounds such as abnormal S-1, Splitting of S-2, presence of S-3 and S-4, Clicks, Snaps and Rubs. Accurate identification of these sounds is helpful in the diagnosis of many Cardiac conditions.
What causes an abnormal sound in the heart?
These sounds are caused by the closing of valves inside your heart. If there are problems in your heart, there may be additional or abnormal sounds. The most common abnormal heart sound is a heart murmur.
What kind of sounds can you hear during auscultation?
Basics of Heart Sounds – S1 and S2 There are 2 main heart sounds that can be heard during auscultation: S 1 and S 2, also affectionately known as ‘lub’ and ‘dub’ respectively.
What’s the difference between normal and pathologic heart sounds?
A murmur is due to turbulence of blood flow and can, at times, encompass all of systole or diastole. The main normal heart sounds are the S1 and the S2 heart sound. The S3 can be normal, at times, but may be pathologic. A S4 heart sound is almost always pathologic.
