Blood turbulence in or near the heart causes murmurs. Using a stethoscope, your doctor will be able to hear these whooshing or swishing murmur sounds. When your heart valves are shutting, a regular heartbeat creates two sounds that sound like “lubb-dupp.” It is possible to have heart murmurs from birth (congenital) or to develop them later in life.
When a person hears a murmur in their heart, it can be harmless (innocent). An innocent heart murmur symptoms are not an indication of heart disease and do not necessitate medical intervention. Detection of abnormal cardiac murmurs necessitates further investigation. Your abnormal heart murmur will be treated by addressing the underlying cause. Stethoscopes are used to listen to your heart during a medical examination. Heart valves make sounds as blood moves through your heart. The doctor listens for these sounds at various points on your chest. Along with various heart murmur symptoms, it also helps the doctor to identify the type of cardiac murmur.
There’s a chance you’ll hear a murmur in your heart. This can be heard during the heart’s normal activity of blood supply.
1. Innocent heart murmur- There is nothing wrong with a person’s heart if their murmur is harmless. In babies and children, this form of murmur is prevalent.
It is possible to detect a murmur in the heart when blood flows more quickly than normal. Several medical conditions might result in an unintentional cardiac murmur, including exercising one’s body, Pregnancy, and Fever. Being unable to supply your body’s tissues with enough oxygen because of a lack of healthy red blood cells (anaemia), Thyroid hormone levels are too high (hyperthyroidism), Adolescence and other periods of fast growth. For the most part, if you have a cardiac murmur that is harmless, it will go away on its own over time.
2. Abnormal heart murmur- The most common heart murmur causes in adults is an issue with the heart valves. When a child has an abnormal heart murmur, it is most likely due to cardiac structural abnormalities (congenital heart defects). Several different birth abnormalities can be heart murmur causes.
Why do you hear a heart murmur?
People are usually ignorant of their heartbeats, however, they do become aware following heart murmur symptoms. This could be because their heart is beating excessively loudly, slowly, or erratically. A sensation that your heart is racing, hammering, fluttering, or skipping a beat, which can be uncomfortable but are seldom a heart murmur symptom.
One of the most prevalent causes of a heart murmur is a condition known as valvular heart disease.
Blood flow is restricted by a narrow, tight, and stiff valve called stenosis. A valve that does not close entirely, permitting reverse flow is known as having valve regurgitation (a “leaky” valve). The abnormal cardiac sound is caused by aberrant valve alterations (murmur).
Heart murmurs can also be caused by:
Reasons for heart murmurs that aren’t related to the heart itself. Several medical diseases can induce murmurs in the heart other than valvular heart disease, including:

If you have a harmless heart murmur, you are unlikely to experience any further heart murmur symptoms or indicators.
When an aberrant cardiac murmur is present, it might lead to the following heart murmur symptoms: Skin that seems to be bluish, particularly on the hands and lips, Irritation or a rapid rise in body weight, a feeling of breathlessness, Coughing fits, Hepatitis C, Neck veins that have swelled in size. Failure to thrive and grow normally in newborns is a heart murmur symptom of anorexia. Sweating profusely although doing little or nothing, Heartache, Dizziness, and Fainting are also some heart murmur symptoms.
If your heart murmur symptoms indicate that the cardiac murmur is of an innocent type then don’t necessitate medical attention because the heart is otherwise healthy. When a sickness, such as a fever or an overactive thyroid (hyperthyroidism), causes an innocent murmur, the ailment will be treated and the murmur will disappear. Over time, your doctor regularly monitors an abnormal heart murmur. Murmurs can be treated with medicine or surgery, depending on the heart murmur symptoms and causes.
Your doctor will prescribe a drug based on the exact cardiac condition you have. Some of the medications that your doctor may prescribe to you include:
Drugs that impede the action of beta-adrenergic receptor Blood pressure and heart rate are lowered as a result of taking these medications. Some sorts of heart valve disorders are treated with them. Preventing bacteria from entering the heart’s lining was a common recommendation made by doctors for patients with abnormal heart murmurs before they visited the dentist or underwent heart surgery (infective endocarditis). Antibiotics are no longer recommended for patients unless they have an artificial heart valve, a history of heart valve infection, or a congenital heart abnormality that raises their risk of infective endocarditis.
FAQ’s
Sometimes it’s harmless and doesn’t cause any problems. But in some cases, it can be a sign of a heart problem. It’s essential to see a doctor to find out the cause of the murmur and if it needs treatment.
A heart murmur itself isn’t something that needs to be cured because it’s just a sound. However, the underlying cause of the murmur may need treatment. Depending on what’s causing the murmur, it might be possible to treat or manage the condition effectively.
Preventing a heart murmur often involves taking care of your heart health. This includes eating a healthy diet, staying active, managing stress, avoiding smoking, and getting regular check-ups with your doctor. These habits can help reduce the risk of developing conditions that could lead to a heart murmur.
Treatment for a heart murmur depends on its cause. If the murmur is due to an underlying heart condition, treatment may involve medication, lifestyle changes, or, in some cases, surgery. Your doctor will determine the best course of action based on the cause and severity of the murmur.
Heart murmurs can be caused by different things. Valve problems, like damage or irregularities in the heart valves, can make blood flow turbulently, causing a murmur. Holes in the heart, called septal defects, can also lead to abnormal blood flow and murmurs. Conditions that boost blood flow through the heart, such as anaemia or hyperthyroidism, can sometimes result in murmurs too.
