What are the abnormal heart sounds?
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. A typical heartbeat makes two sounds like "lubb-dupp" (sometimes described as "lub-DUP") when the heart valves are closing.
What does S1 S2 S3 and S4 heart sounds represent?
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. Heart sounds can be described by their intensity, pitch, location, quality and timing in the cardiac cycle.
Is S3 an abnormal heart sound?
A S3 can be a normal finding in children, pregnant females and well-trained athletes; however, a S4 heart sound is almost always abnormal. CLINICAL PEARL: A S3 heart sound is often a sign of systolic heart failure, however it may sometimes be a normal finding.
Are S3 and S4 abnormal 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.
