Experience the Clarity of S4 Sound Rediscovering the Essence of Music and Sound

The S4 heart sound (aka an "atrial gallop") is heard late in diastole, occurring during the atrial filling phase and coincides with the ... The fourth heart sound (S4), also known as the “atrial gallop,” occurs just before S1 when the atria contract to force blood into the left ventricle. The fourth heart sound or S 4 is an extra heart sound that occurs during late diastole, immediately before the normal two "lub-dub" heart sounds. The fourth heart sound is a low-pitched sound coincident with late diastolic filling of the ventricle due to atrial contraction. An S4 heart sound is a low-pitched sound that occurs toward the end of the diastole. In some cases, an underlying health condition, ... The fourth heart sound (S4) is an abnormal heart sound that can be heard immediately before S1 and indicates increased resistance to ventricular filling. The S3 and S4 heart sounds are both low pitch heart sounds heard in diastole. They differ when they are heard in diastole, S3 being heard ... The S4 heart sound (aka an "atrial gallop") is heard late in diastole, occurring during the atrial filling phase and coincides with the ... The S4 heart sound is a presystolic heart sound occurring immediately before S1 associated with reduced ventricular compliance. What is an S4 Heart Sound? Fourth heart sounds are low in frequency, occurring just before the first heart sound. It is best heard with the ...
