What does a pediatric heart murmur sound like?

​When doctors listen to a child’s heart, what they usually hear is a simple rhythm: “lub-dub, lub-dub, lub-dub…” Sometimes, they’ll hear an extra sound in between the lub and the dub. That extra sound is called a heart murmur.

What sound does a systolic murmur make?

Heart murmurs are sounds — such as whooshing or swishing — made by turbulent blood in or near your heart. Your doctor can hear these sounds with a stethoscope. A normal heartbeat makes two sounds like “lubb-dupp” (sometimes described as “lub-DUP”) when your heart valves are closing.

Which murmur is normal in children?

One common type of normal murmur is Still’s murmur, named for the doctor who first described it. This murmur is most often heard in healthy kids 3 to 7 years old. A normal murmur can get louder when the blood flows faster through the heart, like when kids have a fever or run around.

What is systolic murmur?

Definition. A murmur is a series of vibrations of variable duration, audible with a stethoscope at the chest wall, that emanates from the heart or great vessels. A systolic murmur is a murmur that begins during or after the first heart sound and ends before or during the second heart sound.

What does VSD murmur sound like?

In moderate, high-flow VSDs, the murmur is often very loud and accompanied by a thrill (grade 4 or 5 murmur). With large defects allowing equalization of left ventricular and right ventricular pressures, the systolic murmur is often attenuated.

What are systolic and diastolic murmurs?

Systolic murmur – occurs during a heart muscle contraction. Systolic murmurs are divided into ejection murmurs (due to blood flow through a narrowed vessel or irregular valve) and regurgitant murmurs. Diastolic murmur – occurs during heart muscle relaxation between beats.

What can cause a systolic murmur?

Systolic murmurs (SM) are generated by conditions such as ventricular septal defect, aortic stenosis (AS), pulmonary stenosis (PS), mitral insufficiency (MI), and tricuspid insufficiency (TI).

What does a systolic murmur sound like?

Sometimes, unusual swishing or whistling sounds might be heard along with the normal ‘lub-dub’. These are referred to as heart murmurs. When the swishing sound is heard during a heart’s muscle contraction, it is referred to as a systolic murmur.

What are the grades of murmur intensity?

I/VI: Barely audible

  • II/VI: Faint but easily audible
  • III/VI: Loud murmur without a palpable thrill
  • IV/VI: Loud murmur with a palpable thrill
  • V/VI: Very loud murmur heard with stethoscope lightly on chest
  • VI/VI: Very loud murmur that can be heard without a stethoscope

    • Is it possible to hear a murmur?

    It is absolutely possible to hear a murmur without a stethoscope. If it wasn’t audible before and now it is, get it checked out. You don’t want to wait until you sound like a washing machine to look into it.

    Do heart murmurs go away?

    Some heart murmurs can go away (such as those caused by exercise) and some are always there (such as those caused by heart valve abnormalities). There is no cure per se, but this is largely because a heart murmur itself is not a disease. There are two types of murmurs: innocent and abnormal. A.
