Understanding The Systolic Murmurs List: What Your Heart Sounds Might Tell You
Have you ever heard someone talk about a heart murmur and wondered what it truly means? It can sound a bit scary, that is, when you first hear the words. Your heart, of course, makes sounds as it does its job. These sounds are usually quite steady. Sometimes, though, doctors hear something a little different. This can be a murmur. We are going to talk about a specific kind of sound today. It is called a systolic murmur.
This discussion will help you get a better sense of what a systolic murmur is. We will look at what causes them. Also, we will see when they are just a normal variation. Or, we will see when they might point to something that needs more attention. It is good to be informed about your body. This knowledge helps you talk with your doctor. You can ask good questions, you know, and feel more prepared.
Learning about the different types of heart sounds is actually pretty helpful. It gives you a way to think about your heart's health. We will go through a list of common systolic murmurs. This way, you can get a clearer picture. You will understand what doctors listen for. This article aims to give you a good overview. It is about something important. It is about your heart's rhythm and its sounds.

What Are Systolic Murmurs?
A systolic murmur is a sound a doctor hears when listening to your heart. It happens during a specific part of your heartbeat. This part is when your heart squeezes. When the heart squeezes, it is called a contraction, you know. This is when blood leaves the heart and goes out to your body. My text states, "A murmur that occurs when blood leaves the heart (systolic murmur) generally is an innocent heart murmur." This is a key point to keep in mind.
The heart has two main phases of its beat. One is systole. This is when the heart muscle tightens. It pushes blood out. The other phase is diastole. This is when the heart muscle relaxes. It fills with blood. So, a systolic murmur occurs during that first phase. It is when the heart is actively pumping blood away. This is quite distinct from a diastolic murmur, which happens when the heart is filling.
Blood pressure readings also have two numbers. The top number, as a matter of fact, is called systolic pressure. This number shows the pressure in your arteries when your heart beats. My text points out that isolated systolic hypertension happens when this top number is high. It is 130 mm Hg or more. The bottom number is less than 80 mm Hg. This shows how systolic action is linked to your overall body function.

The sound of a murmur comes from blood flowing in an unusual way. It might be flowing through a heart valve that is a little narrow. Or, it could be a valve that does not close completely. Sometimes, it is blood flowing through a hole in the heart wall. These things can make a whooshing or swishing sound. It is different from the regular "lub-dub" of a healthy heart. Doctors use a special tool. It is called a stethoscope. They listen carefully to these sounds. They can tell a lot from what they hear, really.
So, a systolic murmur is basically an extra sound. It is heard during the heart's pumping phase. It could be harmless. Or, it might suggest a heart issue. This is why a doctor's check-up is important. They can tell you what kind of murmur you have. They can also tell you what it means for you. It is quite important to get this checked out properly.
Common Types of Systolic Murmurs
There are several kinds of systolic murmurs. Some are not a cause for worry. Others might need more attention. Knowing the differences can be helpful. Here is a list of some common ones you might hear about. We will go through them one by one. This will give you a better idea of what each one means.
Innocent Systolic Murmurs
An innocent systolic murmur is very common. It is not caused by any heart problem. My text mentions that a murmur occurring when blood leaves the heart "generally is an innocent heart murmur." This is true for many people, especially children. They are often called "flow murmurs." This is because they happen when blood flows faster than usual. Or, it might be when the heart's chambers are filling more quickly. This can happen during fever. It can also happen during exercise. Or, it might be during periods of fast growth.
These murmurs are harmless. They do not need any treatment. People with innocent murmurs live completely normal lives. They do not have any symptoms related to their heart. The sound might change. It could even go away over time. This is particularly true for children. A doctor can tell you if a murmur is innocent. They do this after listening carefully. They might do a few simple tests. This helps confirm it. You know, it is a good thing when it is just an innocent murmur.
Aortic Stenosis
Aortic stenosis is a different kind of systolic murmur. It happens when the aortic valve narrows. This valve is like a door. It lets blood go from the heart's main pumping chamber. This is the left ventricle. It goes into the body's largest artery. This is the aorta. When this valve narrows, it is harder for blood to get through. It is like trying to push water through a small hose. The heart has to work harder. This creates a distinct sound.
This murmur is often heard over the upper right side of the chest. It can sometimes travel up to the neck. People with aortic stenosis might feel tired. They could also have chest discomfort. Or, they might feel dizzy. This is especially true with effort. It can be a serious condition. Doctors usually keep a close eye on it. Sometimes, treatment is needed. This might involve medicine. Or, it could mean fixing the valve. It depends on how narrow the valve has become.
Mitral Regurgitation
Mitral regurgitation is another common cause of a systolic murmur. This happens when the mitral valve does not close tightly. The mitral valve is between the left upper and lower chambers of the heart. When it does not close all the way, blood leaks backward. It leaks from the lower chamber. It goes back into the upper chamber. This happens each time the heart pumps. It is like a door that swings open a little. It lets some things go back inside. This backward flow makes a sound.
This murmur is often heard best over the tip of the heart. This is on the left side of the chest. The sound can sometimes travel to the armpit. People might feel short of breath. They could also feel tired. Or, they might have swelling in their legs. These feelings often get worse over time. Doctors will watch this condition. They might suggest medicines. Or, they might suggest other procedures. This helps manage the symptoms. It also helps protect the heart. It is something that can affect your daily life.
Tricuspid Regurgitation
Tricuspid regurgitation is similar to mitral regurgitation. But it involves a different valve. This is the tricuspid valve. This valve is between the right upper and lower chambers of the heart. Just like with the mitral valve, it does not close properly. So, blood leaks backward. It leaks from the right lower chamber. It goes back into the right upper chamber. This happens during the heart's squeeze. This creates a specific murmur sound. It is a bit like a leaky faucet sound, in a way.
This murmur is often heard best over the lower left side of the breastbone. It might get louder when you breathe in. Symptoms can include swelling in the legs or belly. You might also feel tired. This condition is often linked to other heart or lung issues. Treatment focuses on managing the underlying cause. It also focuses on reducing symptoms. It is something doctors pay close attention to. They want to make sure your heart works as well as it can.
Ventricular Septal Defect (VSD)
A ventricular septal defect, or VSD, is a hole in the heart. This hole is in the wall between the heart's two lower chambers. These are the ventricles. Normally, this wall is solid. It keeps blood from mixing. When there is a hole, blood can flow through it. It flows from the left side to the right side. This happens during the heart's pumping phase. This flow creates a very noticeable murmur. It is often quite loud. This is because of the pressure difference. It is like water rushing through a small opening.
VSDs can be present from birth. Some small VSDs might close on their own. Larger ones might need treatment. This could be medicine. Or, it could be surgery. Symptoms can vary. They depend on the size of the hole. Babies might have trouble feeding. They might not gain weight well. Older children or adults might feel tired. They could also have shortness of breath. This is especially true with activity. Doctors monitor VSDs carefully. They decide the best course of action. It is a condition that requires specific care.
Hypertrophic Cardiomyopathy (HCM)
Hypertrophic cardiomyopathy, or HCM, is a condition. In HCM, the heart muscle becomes too thick. This thickening often happens in the wall between the two lower chambers. This makes it harder for the heart to pump blood. It can also block blood flow. This blockage often happens during the systolic phase. It creates a murmur. This is a very specific type of murmur. It is caused by the heart's own structure changing.
The murmur from HCM can change with different body positions. People with HCM might have chest pain. They could also feel dizzy. Or, they might faint. This is especially true during exercise. It can be a serious condition. It sometimes runs in families. Doctors use various tests to diagnose HCM. These tests include imaging of the heart. Treatment aims to reduce symptoms. It also aims to prevent complications. It might involve medicines. Or, it could involve procedures. It is important to get regular check-ups if you have HCM. This is to make sure your heart is doing okay.
When to Pay Attention to a Systolic Murmur
Many systolic murmurs are innocent. They do not cause any issues. However, some murmurs can be a sign of an underlying heart condition. It is important to know when to seek medical advice. If you have a murmur, your doctor will tell you if it is innocent. They will also tell you if it needs more investigation. This is very important. You should always follow their guidance.
You should pay attention to new symptoms. If you develop shortness of breath, for instance, that is a sign. Or, if you feel chest discomfort. Also, if you experience dizziness or fainting spells. Swelling in your legs or ankles can also be a sign. These could be signs that a murmur is not innocent. They might suggest a heart problem is getting worse. Or, they might suggest a new one has started. It is always a good idea to tell your doctor about any new feelings. This is so they can check things out.
Changes in your energy levels can also be a hint. If you find yourself more tired than usual. Or, if you cannot do activities you once enjoyed. These are things to mention. Children might have trouble growing. Or, they might have difficulty feeding. These are also signs to watch for. Your doctor will assess these symptoms. They will decide if more tests are needed. This helps them understand what is going on with your heart. It is about staying aware of your body's signals.
How Systolic Murmurs Are Found
Systolic murmurs are usually found during a routine physical exam. Your doctor uses a stethoscope. They listen to your heart sounds. This is a very common part of any check-up. They listen for the timing of the murmur. They also listen for its loudness. They listen for where it is heard best. And, they listen for how it changes with breathing or body position. All these details help them understand the murmur. It gives them clues, you know, about its cause.
If a murmur is heard, your doctor might recommend more tests. One common test is an echocardiogram. This uses sound waves. It creates pictures of your heart. It shows the heart's chambers. It also shows the valves. This test can show if there are any problems with the heart's structure. It can show if there are problems with how blood flows. It is a very helpful tool. It gives doctors a good look inside your heart.
Other tests might include an electrocardiogram (ECG). This checks the heart's electrical activity. Or, it might be a chest X-ray. This shows the size and shape of the heart. Sometimes, a cardiac MRI is used. This gives even more detailed pictures. These tests help confirm a diagnosis. They also help determine the best way to manage any heart condition. They are all about getting a clear picture of your heart's health. You can learn more about heart health on our site.
Living with a Systolic Murmur
Living with a systolic murmur depends on its cause. If it is an innocent murmur, you likely do not need to do anything special. You can continue your normal activities. You do not need any treatment. It is just a sound. It does not affect your heart's health. This is quite reassuring for many people.
If the murmur is due to an underlying heart condition, management will depend on that condition. Your doctor will discuss the best plan for you. This might involve regular check-ups. It could also involve medicines. Or, it might involve lifestyle adjustments. For instance, my text mentions "10 ways to control high blood pressure without medication." These include making lifestyle changes. These changes can help lower blood pressure. They can also reduce heart disease risk. This is generally good for heart health. This applies even if you have a murmur.
These lifestyle changes can include eating a balanced diet. It also includes getting regular physical activity. Managing stress is also important. Quitting smoking is a big one. Limiting alcohol intake helps too. These steps support overall heart wellness. They can help your heart work better. This is true whether you have a murmur or not. It is about taking good care of yourself. This helps your heart stay as healthy as possible. You can find more
