How to distinguish S3 and S4?

Background. 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.Clinical pearl: a s4 heart sound occurs during active lv filling when atrial contraction forces blood into a noncompliant lv. Therefore, any condition that creates a noncompliant lv will produce a s4, while any condition that creates an overly compliant lv will produce a s3, as described above.The fourth heart sound (S4) is an abnormal heart sound that can be heard immediately before S1 and indicates increased resistance to ventricular filling due to high atrial pressure or increased ventricular thickness. The presence of an S4 may indicate myocardial infarction or shock.The third heart sound (S3), caused by rapid deceleration of the blood against a stiff ventricle during early diastolic filling, is an early and specific sign of heart failure and elevated filling pressure.
