What are 3 abnormal heart sounds?
Abnormal Heart Sounds and Murmurs – 62
- S1 (e.g., mitral stenosis, atrial fibrillation)
- S2 (e.g., hypertension, aortic stenosis)
- S3 (e.g., congestive heart failure)
- S4 (e.g, hypertension)
- Abnormal splitting (e.g., atrial septal defect)
What do the 4 heart sounds represent?
The fourth heart sound (S4), when audible, is caused by vibration of the ventricular wall during atrial contraction. This sound is usually associated with a stiffened ventricle (low ventricular compliance), and therefore is heard in patients with ventricular hypertrophy, myocardial ischemia, or in older adults.
What do the sounds of the heart mean?
In 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.
Is S3 a murmur?
The third heart sound or S3 is a rare extra heart sound that occurs soon after the normal two “lub-dub” heart sounds (S1 and S2). S3 is associated with heart failure….

What causes the heart sounds?
Heart sounds are created from blood flowing through the heart chambers as the cardiac valves open and close during the cardiac cycle. Vibrations of these structures from the blood flow create audible sounds — the more turbulent the blood flow, the more vibrations that get created.
What is the treatment for heart murmur?
Surgery may be needed to correct a damaged or leaky valve that causes a heart murmur. Depending on your heart condition, your doctor may recommend one of several heart valve treatment options.
What causes S2 sound?
The second heart sound (S2) represents closure of the semilunar (aortic and pulmonary) valves (point d). S2 is normally split because the aortic valve (A2) closes before the pulmonary valve (P2).
What causes the characteristic heart sounds?
What are the abnormalities of the heart sounds?
The most common abnormal heart sound is a heart murmur. A murmur is a blowing, whooshing, or rasping sound that occurs during your heartbeat. There are two kinds of heart murmurs: An innocent murmur can be found in children and adults. It’s caused by the sound of blood moving normally through the heart.
What causes heart sounds S3 S4?
As with S3, the fourth heart sound is thought to be caused by the vibration of valves, supporting structures, and the ventricular walls. An abnormal S4 is heard in people with conditions that increase resistance to ventricular filling, such as a weak left ventricle.
What is the medical term meaning abnormal heart sound?
A heart murmur is an unusual sound heard between heartbeats. If your doctor hears a “murmur” or any other abnormal sounds coming from your heart, it may be an early indicator of a serious heart condition. In many cases, heart murmurs and other abnormal heart sounds can only be detected when your doctor listens to your heart using a stethoscope.
Heart sounds are caused by the closure of heart valves. The first sound you hear is S1 and is caused by the closure of the atrioventricular valves (AV) TRICUSPID AND MITRAL VALVES. This sounds like “LUB”.
