Symptoms Of The Noises In The Heart Of A Newborn
There are no rules without exception, however, diastolic murmurs are reflections of heart diseases. Noises that are heard constantly – too.
Systolic murmur in the heart of a newborn is treated not so uniquely. Most of the early systolic murmurs are functional, however, the pansystolic ones, audible throughout the systolic phase without a pause between heart tone and noise, are also considered dangerous. Such noises speak of the development of valvular insufficiency and the reverse flow of blood from the ventricle to the atrium or the non-spreading of the interventricular septum. Depending on the size of the hole between the left and right ventricles, this pathology is expressed by oxygen deficiency, and the child develops dyspnea.
Systolic murmurs may also indicate a narrowing of the aortic or pulmonary artery mouth.
Small anomalies in the development of the heart appear when listening to periodic systolic clicks.
Diastolic type of noise occurs mainly in the anomalies of the semilunar valves, which provide the direction of blood flow from the ventricles to the aorta and pulmonary artery, and also – with mitral constrictions. Noise in narrowing the diameter of the aortic or pulmonary artery is usually systolic.
Venous duct – communication with the umbilical cord of the central veins and venules of the fetus, is blocked by the child during the first-second hour of life, in some cases, more time passes or the venous duct remains.
Infections That Destroy The Structure Of The Heart
- Calcification of the valves. As you become older, your valves can harden or thicken, resulting in mitral stenosis or aortic valve stenosis. Valves can become narrowed , making blood flow through your heart more difficult and leading in murmurs.
- Endocarditis When bacteria or other germs from some other area of the body, such as your mouth, migrate through your bloodstream and become trapped in your heart, an infection of the inner lining of your heart and valves occurs. Endocarditis can completely ruin your heart valves if remain unattended. People who already have cardiac valve abnormalities are more likely to develop this illness.
- Rheumatic fever Though rheumatic fever is increasingly uncommon in India, it is a dangerous condition that can develop if a strep throat infection is not treated promptly or completely. It can damage your heart valves permanently and prevent proper blood passage through your heart. Read Heart Valve Diseases
What Are Heart Valves
Your heart is a strong muscle about the size of the palm of your hand. Your body depends on the hearts pumping action to deliver oxygen- and nutrient-rich blood to the bodys cells. When the cells are nourished properly, the body can function normally. Just like an engine makes a car go, the heart keeps your body running. The heart has two pumps separated by an inner wall called the septum. The right side of the heart pumps blood to the lungs to pick up oxygen. The left side of the heart receives the oxygen-rich blood from the lungs and pumps it to the body.
The heart has four chambers 7), two on the right and two on the left:
- Two upper chambers are called atrium . The atria collect blood as it flows into the heart.
- Two lower chambers are called ventricles. The ventricles pump blood out of the heart to the lungs or other parts of the body.
The heart also has four valves that open and close to let blood flow from the atria to the ventricles and from the ventricles into the two large arteries connected to the heart in only one direction when the heart contracts . The four heart valves are:
- Tricuspid valve, located between the right atrium and right ventricle
- Pulmonary or pulmonic valve, between the right ventricle and the pulmonary artery. This artery carries blood from the heart to the lungs.
- Mitral valve, between the left atrium and left ventricle
- Aortic valve, between the left ventricle and the aorta. This aorta carries blood from the heart to the body.

What Are Heart Murmurs In Newborns
Many parents will be surprised to learn that a heart murmur isnt a disease. Rather, it is a symptom of an underlying condition. If your child has a heart murmur, your pediatrician will hear it while listening to your child\s heartbeat with a stethoscope.
As the name implies, a heart murmur is an unusual sound produced by the heart in the course of its normal pumping action. Murmurs in children are relatively common and often do not signify any serious problem. The extra sounds might be nothing more than those of normal blood flowing through a healthy heart.
If a murmur is heard at birth, however, or during the first six months of life, your pediatrician might want to pursue further testing to rule out more serious congenital heart defects. Some murmurs are caused by septal defects, which occur when the walls separating the left and right sides of the heart have an abnormality that allows blood to mix. Murmurs can also signify underlying blood vessel disease.
A murmur is usually the only symptom of patent ductus arteriosus , a potentially serious condition in which the ductus arteriosus fails to properly close at or shortly after birth. This causes blood to circulate abnormally between two major arteries near the heart.

Types Of Heart Murmurs
A large proportion of normal newborns and children have harmless murmurs. Most of these murmurs occur in systole, the period when the ventricles are contracting. These murmurs do not spread over a large area of the chest. Their intensity changes as your child changes position.
Your pediatrician will probably want to investigate these murmurs, though, if:
- Your child has other abnormalities of the circulatory system
- Your child has unusual features
- Your child is not growing well
Pathological murmurs are often harsh and spread all over the chest. They may be heard in diastole , or even continuously. Children with pathological murmurs will often have other signs of illness.
Murmurs are graded in intensity from Grade 1 to 6. The first four grades can only be heard with a stethoscope, but grades five and six can be felt by putting a hand on the chest over the heart.

How Soon Can A Heart Murmur Be Identified
The heart and lungs of a baby undergo functional and structural changes for weeks, and even months after birth. Therefore, it may take days, weeks or months for a murmur-causing heart problem to develop.
On the other hand, a defect which causes a murmur when the child is born may clear up in a couple of days or weeks, as the heart develops. An example of this is a condition known as ‘ductus-arteriosus’, which usually disappears within three months of birth.
Atrial septal defects and peri-membranous ventricular septal defects are referred to as ‘holes’ in the heart in layman’s terms. These can also cause heart murmurs in babies. However, these too can disappear in a couple of years.

Heart Murmurs In Newborns And Children
When your pediatrician hears a childhood heart murmur, they try to assess whether it is a harmless murmur or a sign of a dangerous problem.
They will take note of the following.
- The loudness of the murmur
- The pitch, low or high
- The location where the murmur is loudest
- The spread â whether it can be heard over the sides and back of your child or baby’s chest
- The timing of the murmur in relation to the first and second heartbeats
These details enable your pediatrician to decide whether the childhood heart murmur is innocuous or requires further assessment by a pediatric cardiologist.

Testing And Diagnosis Of Heart Murmur In Children
Doctors can evaluate many characteristics of the murmur to determine if it is normal or abnormal, including:
- If it is loud or soft
- If it is high- or low-pitched
- Where on the chest or back it can be heard
- If there are differences in the sound based on your child’s position
- When the murmur occurs relative to the first and second heart sounds
If your child’s primary doctor thinks that the murmur is normal or innocent, he or she will note the murmur on the patient chart and listen again at later checkups for changes. If you switch doctors, make sure to tell the new doctor about the innocent murmur. If your child’s doctor feels comfortable that the murmur is normal, there is no need for further cardiology evaluation.
Sometimes the doctor will be concerned that the murmur is not normal. In these cases, you may be referred to a pediatric cardiologist, a doctor who specializes in heart problems in children. It is very important to see the pediatric cardiologist if your child’s doctor tells you to do so.
A pediatric cardiologist will perform a full evaluation of your child’s health, including getting a history and performing an examination, as well as possibly ordering heart tests such as:
- Electrocardiogram: a record of the electrical activity of the heart
- Echocardiogram : sound waves create an image of the heart

How Are Heart Murmurs Treated In A Child
Treatment will depend on your childs symptoms, age, and general health. It will also depend on how severe the condition is.
Many heart murmurs are normal, extra sounds in children with strong, healthy hearts. These children dont need treatment. Some of these heart murmurs may go away on their own with time.
If the murmur is from a congenital heart defect, treatment may include medicine, procedures, or surgery. If the murmur is from another condition, the heart murmur will usually lessen or go away once the condition is treated.

Initially, a childs healthy heart and lungs can often overcome the stress associated with congenital heart disease. However, after an extended period, a child may begin to have complications from their murmur.
Abnormal blood flow creating the murmur can cause abnormal pressure in the heart chambers, leading to heart exhaustion and changes to the heart and lungs themselves.
Heart Murmur: What To Expect If Your Child Is Diagnosed
Heart murmurs in children are very common. As many as half of all children will have a heart murmur at some point before 18 years of age. It is important to understand what causes a heart murmur and what needs to be done to evaluate them.
What Is a Heart Murmur?
Every time the heart beats, two normal sounds are generated that can be heard using a stethoscope. A heart murmur is an extra sound that is created by the sound of blood flowing through the heart. The most common heart murmur is caused by normal blood flowing through the heart. These innocent murmurs can be heard at any time throughout childhood and are frequently heard for the first time if a child has an illness, especially if associated with a fever.
Innocent murmurs may simply diagnosed with a health care provider listening to your childs heart or may involve other testing, such as an electrocardiogram or echocardiogram. Innocent murmurs do not affect your childs health and will not affect his or her development. A child with an innocent murmur will have no restrictions and will not need to be followed by a pediatric cardiologist. If your pediatrician or care provider isnt sure what is causing the murmur they may refer you to a pediatric cardiologist to evaluate your childs murmur.

What Is Heart Murmur In Babies
According to the American Academy of Pediatrics , a heart murmur in babies is just a noise heard between heartbeats. Heart murmurs in babies are fairly common and are usually innocent or normal, despite the fact that they can be frightening for parents.
Types of murmurs include:
- Systolic murmur. A heart murmur occurs when the heart contracts.
- Diastolic murmur. A heart murmur occurs when the heart relaxes.
- Continuous murmur. A heart murmur occurs throughout. the heartbeat.
Innocent heart murmurs in babies are completely harmless, and a large percentage of youngsters will have experienced them at some point in their lives. A healthy heart pumps blood normally, resulting in these murmurs.
If your child has such a murmur, it will most likely be noticed during a regular examination when they are between the ages of 1 and 5. By listening to a murmur with a stethoscope, your childs doctor can typically detect if its normal.
How To Diagnose A Heart Murmur
Heart listening exam conducted with the help of a stethoscope helps hear a murmur. It is difficult to hear a murmur when a child is uncooperative and cries a lot. It is important to calm the child first before conducting the exam.
Depending on their loudness or intensity, heart murmurs are rated on a scale of 1 to 6 â Grade 1 is barely audible, while Grade 6 is the loudest. The doctor will also pay attention to the location where the murmur is best heard and also consider if the murmur is soft or harsh blowing. The doctor will also consider if the murmur changes when your child changes position. She or he will consider all these points and then decide if you should take your child to a pediatric cardiologist.

Symptoms Of Heart Murmur In Babies
Babies with innocent murmurs have no other symptoms aside from abnormal heart sounds. In the case of children having pathological heart murmurs, one or more of the following symptoms may be present. They differ based on the issue.
- Poor nutrition, eating habits, or weight gain
- Shortness of breath or breathing fast
- Enlarged neck veins
- Feeling dizzy or faint
- Skin that is bluish, especially around the lips and fingertips
- Oedema of the lower legs, ankles, and feet, as well as the belly , liver, and neck veins
The symptoms of a cardiac murmur can be similar to those of other illnesses. Make an appointment for your child to see his or her doctor for a diagnosis.
Your doctor and a paediatric cardiologist can evaluate if the murmur is innocent or if there is a specific heart problem. If an issue arises, the paediatric cardiologist will know how to effectively address it.
Does Your Child Need To See A Doctor About Heart Murmur
Any problems with your babys heart are likely to be picked up at birth, when the midwife or paediatrician checks your baby. If problems arent detected then, theyll probably be picked up in checks during your babys first few weeks.
Sometimes heart murmurs are picked up during general check-ups or check-ups for other issues like infections.
Go to a hospital emergency department or call 000 for an ambulance straight away if your child is having trouble breathing, suddenly becomes pale or blue, or youre concerned your child is very unwell.
