The S3 and S4 heart sounds may occur together in some patients and produce a “quadruple rhythm,” or if fused, a “summation gallop.” This may occur in patients with a left ventricular aneurysm, end-stage ischemic cardiomyopathy, or concomitant ischemia and left ventricular dysfunction.

What causes S3 heart sounds?
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 conditions cause S3 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.

S3 Vs S4 Heart Sound
What can cause an S4 heart sound?
Commonly, this results from conditions that can lead to ventricular hypertrophy. A left-sided fourth heart sound is frequently present in patients with systemic hypertension, aortic stenosis, or hypertrophic cardiomyopathv. A left ventricular fourth heart sound is common also in patients with coronary heart disease.
Does mitral stenosis cause S3?
Whenever an S3 is found in mitral stenosis, either it is thought that the stenosis is too mild to prevent rapid ventricular filling or the sound is attributed to coexistent valvular regurgitation or right ventricular failure.
What condition causes S4?
A S4 heart soundheart soundIn healthy adults, there are two normal heart sounds, often described as a lub and a dub that occur in sequence with each heartbeat. These are the first heart sound (S1) and second heart sound (S2), produced by the closing of the atrioventricular valves and semilunar valves, respectively.https://en.wikipedia.org › wiki › Heart_soundsHeart sounds - Wikipedia can be an important sign of diastolic heart failure or active ischemia and is rarely a normal finding. Diastolic heart failure frequently results from severe left ventricular hypertrophy, or LVH, resulting in impaired relaxation (compliance) of the LV. In this setting, a S4 is often heard.

What does a S3 indicate?
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 does S3 sounds indicate?
CLINICAL PEARL: A S3 heart sound is often a sign of systolic heart failure, however it may sometimes be a normal finding. A S3 can be an important sign of systolic heart failure because, in this setting, the myocardium is usually overly compliant, resulting in a dilated LV; this can be seen in the image below.
