There are 4 types of heart sounds –. S1 – “lub” caused by the closing of the AV valves. S2 – “dub” caused by the closing of semilunar valves. S3 – linked with flow of blood into the ventricles. S4 – linked with atrial contraction. Generally, the heart makes two sounds – “lub” and “dub”. The third and fourth sounds ... An extra sound just before S1 is an S4 heart sound, or atrial gallop. An S4 sound often is associated with hypertensive heart disease. A sound that follows S1 and S2 is called an S3 heart sound or a ventricular gallop.

First, it could be due to a heart condition known as atrial fibrillation, which is when the heart’s upper chambers (atria) contract irregularly. This can cause a “lub-dub” sound instead of the normal “lub-dub-dub” sound of a healthy heart. A S4 heart sound, when audible, can be an important sign of diastolic heart failure or active ischemia and is not typically detectable by other means.

Recognition of the third heart sound is therefore crucial for prompt treatment. Heart murmurs are sounds — such as whooshing or swishing — made by rapid, choppy (turbulent) blood flow through the heart. The sounds can be heard with a device called a stethoscope.

(See "Examination of the precordial pulsation" and "Examination of the arterial pulse" and "Examination of the jugular venous pulse" .) This topic will review the auscultation of heart sounds. The auscultation of cardiac murmurs is discussed separately. The other extra heart sound that we've covered is the opening snap. And remember that's associated with mitral stenosis. The other two really important extra heart sounds that we're going to talk about are what are called S3 and S4. And so you'll realize that we have S1 here, S2 here, so these are the next two heart sounds. The fourth heart sound (S4) is a low-pitched, late diastolic sound. So it occurs shortly before the first heart sound. The stethoscope bell should be used, pressing lightly against the chest wall at the lower left sternal border or subxiphoid area. The cadence is similar to 'Tennessee'.Aortic stenosis. hypertension.
