Normally, two distinct sounds are heard through the stethoscope: a low, slightly prolonged “lub” (first sound) occurring at the beginning of ventricular contraction, or systole, and produced by closure of the mitral
Mitral valve
The mitral valve, also known as the bicuspid valve or left atrioventricular valve, is a valve with two flaps in the heart, that lies between the left atrium and the left ventricle. The mitral valve and the tricuspid valve are known collectively as the atrioventricular valves because they lie between the atria and the ventricles of the heart.
Can You Hear Your Heart Beat with a stethoscope?
You can hear your heart make sounds when it beats. Sounds can range in volume from barely audible to easy to hear with a stethoscope. Abnormal heart sounds are called heart murmurs. These sounds can include rasping, whooshing, or blowing sounds.
What does a normal heartbeat sound like?
First, here is the sound of a normal heartbeat. You can hear the traditional “lub-dub” as the four heart valves open and close. Next, here is the sound of a heart with aortic stenosis. Finally, here is the sound of heart with mitral valve regurgitation.
What does a heart murmur sound like?
Sounds can range in volume from barely audible to easy to hear with a stethoscope. Abnormal heart sounds are called heart murmurs. These sounds can include rasping, whooshing, or blowing sounds.
What does it mean when you hear a clicking sound in Your Heart?
Clicks or short, high-pitched sounds may also be heard during your regular heartbeat. This could indicate a mitral valve prolapse, when one or both flaps of your mitral valve are too long. This can cause some regurgitation of blood into your left atrium. Rubbing sounds may be heard in people with certain kinds of infections.
What should a normal heart sound like?
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.

What are the four normal heart sounds?
In a healthy adult, the heart makes two sounds, commonly described as 'lub' and 'dub. ' The third and fourth sounds may be heard in some healthy people, but can indicate impairment of the heart function. S1 and S2 are high-pitched and S3 and S4 are low-pitched sounds.
How would you describe a heart sound in nursing?
The S 1 heart sound represents the mitral and tricuspid valves closing before the contraction of the ventricle. S 1 is auscultated as “lub.” The S 2 heart sound signifies aortic and pulmonic valve closure after the ventricles have emptied. S 2 is auscultated as “dub” (see Picturing heart sounds).
Where do you place the stethoscope to listen to heart sounds?
Typically, they put the stethoscope in one or two spots on the front of the chest, over clothing or hospital gown, and listen for a very few cardiac cycles before concluding, “S1, S2 normal, no murmurs.” Brief to the point of incompleteness, such a note disregards the rest of the cardiovascular examination.
What heart sounds do you hear with heart failure?
The pathological S3 is often an early sign of heart failure. If present, the S3 heart sound occurs immediately after the S2, coinciding with the period of rapid ventricular filling, and is a soft and low frequency sound that is best heard with the bell of the stethoscope lightly rested over the chest wall.
Can stethoscope detect heart problems?
A health care provider will perform a physical exam and listen to your chest using a stethoscope. The provider may hear abnormal sounds in your lungs (called crackles), a heart murmur, or other abnormal sounds. You may have a fast or uneven pulse.
What does atrial fibrillation sound like through a stethoscope?
"In atrial fibrillation, it may sound almost like when your shoes are in the dryer, going all over the place." Atrial fibrillation is a type of arrhythmia, which literally means "not rhythmic," hence the somewhat random "shoes in the dryer" effect, which you can also feel in your pulse.
What does a leaky heart valve sound like?
When there's more than a little leakage (a “leaky valve”), the doctor may hear a whooshing sound as some blood moves backward into the left atrium. This is a heart murmur, and it's heard between the normal lub-dub sounds of the heartbeat.
What does a heart murmur sound like through a stethoscope?
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.
Which heart sound is the loudest?
The first heart sound has a booming quality and is lower-pitched, duller, and longer than the second heart sound. It is usually louder at the apex than is the second sound. At the base, however, both components of the second sound are normally louder than the first sound (see Chapter 23, The Second Heart Sound).
What sound does a heart make onomatopoeia?
A normal heartbeat sounds like e.g., lub dub or dub lub, and a murmur heartbeat sound has a noise between dub to lub or lub to dub and extra-systole heart sound is out of beats e.g., lub-lub dub or lub dub-dub [4].

When it comes to what a stethoscope can pick up on there are many different uses and sounds. This is why stethoscopes are so often used by doctors and nurses. This is also one of the first tools that training doctors and nurses get trained to use. Everything from heart, lungs, bowels, and arteries can be listened to with the use of a stethoscope.
Why do we use bells on the chest?
In addition to hearing these things with the bell side of the instrument, we can use it for listening more deeply into one area on the chest. For example, if there's concern the lung fields may have fluid in them, we can use it to see where that might be coming from and what needs to happen next.

Which valve goes from the left ventricle to the pulmonary trunk?
The mitral valve leads from your left atrium to your left ventricle. The pulmonary valve goes from your right ventricle out to your pulmonary trunk. The aortic valve goes from your left ventricle to your aorta. Your pericardial sac surrounds your heart and protects it.
What is the most common abnormal heart sound?
Heart murmurs. 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 : innocent (also called physiological) abnormal. An innocent murmur can be found in children and adults.

What is it called when you hear a loud sound in your heart?
Abnormal heart sounds are called heart murmurs. These sounds can include rasping, whooshing, or blowing sounds. Heart murmurs can occur during different parts of your heartbeat. For instance, they can occur when the blood comes into the heart or when it leaves the heart. Atrial fibrillation (also referred to as AFib or AF) is a type of arrhythmia.
How to diagnose a heart murmur?
Diagnosis of heart murmurs begins with your doctor listening to your heart with a stethoscope. This is often enough to hear the murmur and to classify it. Your doctor may also order imaging tests. For instance, they may order an ultrasound to help see blood flow, or a chest X-ray to see your heart valves.
What is the difference between AFIB and murmurs?
Murmurs are related to how blood is flowing through your heart, particularly the valves that connect the chambers of your heart. AFib, on the other hand, is related to electrical impulses that have become chaotic or disordered and result in an irregular heartbeat rate.
Why do the atria and ventricles beat out of sequence?
Both atria may beat out of sequence, or fibrillate, when this node produces disordered impulses. The fibrillation causes irregular impulses to be transmitted through the ventricles. The result is that the atria and ventricles become uncoordinated and the heartbeats become irregular. Sometimes the cause of AFib is unknown.
Why do murmurs open?
They open to let blood into a chamber and then close to make sure blood does not flow backwards. Many murmurs require no treatment. Some murmurs are more serious and may need treatment. These murmurs are caused by a valve that could be: leaking.
How to reset your heart rate?
Your doctor may try to reset the rhythm of your heart’s electrical system through cardioversion. Cardioversion will be done with an electrical shock to your heart using a defibrillator that has paddles that are applied to your chest wall.
