A healthy heart produces dual graphic sounds – lub dub. The ‘lub’ is a sound caused by a mitral and tricuspid valves shutting during a commencement of a systole (contraction). The ‘dub’ is a gnawing tighten of pulmonic and aortic valves, denoting a finish of a systole.Here is a proof of normal heart sounds, from a University of Washington, Department of Medicine.

Heart murmurs

A heart whimper is an surprising sound that is listened during a heartbeat. Murmurs can be so gloomy that they are hardly noticeable, or extremely shrill that they sound like whooshing. A whimper is radically a swishing sound that is listened when there is an aberrant upsurge of blood opposite a heart valve.

‘A whimper is like a fever,’ explains Dr. MadhuSreedharan, Cardiologist and Director of NIMS Heart Foundation, Trivandrum. ‘You have to examine a reasons for it and afterwards provide it appropriately.’

Causes of heart murmurs

Most heart murmurs are soft and do not need treatment. However, murmurs can also be caused by blood coursing by busy or shop-worn heart valves.

‘Murmurs can be possibly trusting or abnormal. Innocent murmurs do not need any treatment,’ says Dr. Sreedharan.

Innocent heart murmurs

It is not transparent since some people have trusting heart murmurs. They’re simply a sounds of blood issuing by a chambers and valves of a heart. Extra blood issuing by a heart, for instance during childhood or pregnancy, can means trusting murmurs there are expected to be benign. Innocent murmurs do not means symptoms and do not need we to extent activities in any way. A normal whimper might get louder when children run a fever. Treatment is not required in many cases, since as a child grows a normal murmurs turn gradually formidable to hear.

Abnormal heart murmurs

Abnormal heart murmurs are caused by inborn heart defects or acquired heart valve diseases.

Congenital heart defects

Congenital heart defects(CHD) are problems with a structure of a heart that are benefaction right during a birth. These defects are ordinarily found in a interior walls, valves, or arteries and veins that supply blood to a heart. They impact a normal blood upsurge by a heart.

The defects can operation from elementary to life-threatening. They are deliberate to be a many common form of birth defects, and in India, a reported occurrence of CHD is 8 to 10 out of 1000 births. With a diagnosis options that are accessible now, some-more than 75% of infants innate with CHD can tarry a initial year, and lead comparatively normal lives. However, it is critical to start diagnosis early.

Problems with a heart valve, holes in a heart and problems of a heart flesh are a many common defects that means aberrant heart murmurs.

Acquired heart valve disease

Acquired heart valve illness is a many common means of aberrant heart murmurs in a adult population. The illness typically develops as a outcome of another commotion like rheumatic fever, infections, and age associated changes.

Scar hankie shaped from a heart attack, damage to a heart, or high blood vigour can increase and crush heart valves. Also as we get older, calcium deposits on your heart valves might prop and extent a upsurge of blood. This condition is called sclerosis. A singular though life-threatening infection called Infective Endocarditis might also outcome in or wear a heart valve disease.

Rheumatic heat is one of a vital causes of valvular heart diseases in a world. Population surveys conducted in India estimates a superiority of rheumatic heart illness as 1.55 out of 1000 cases.According to a World Heart Foundation, RHD is a many common acquired heart illness in children of a building countries.

RHD is a ongoing heart condition caused by rheumatic fever, a streptococcal infection. ‘It is prevalent in packed areas where a lot of people stay tighten together,’ points out Dr. Sreedharan.

Rheumatic heat affects a joints, heart, and executive shaken system. If left untreated, it leads to critical valvular heart diseases, heart disaster and even death.

If we have a heart murmur

Many people have heart murmurs and continue to lead a normal life. But in some people, a illness can wear and rise discouraging consequences. Untreated heart valve diseases can lead to stroke, heart disaster or genocide due to remarkable cardiac arrest.

There are no medicines to heal heart valve disease. But a healthy lifestyle and remedy can soothe many complications and symptoms. Timely diagnosis will also assistance forestall growth of life-threatening conditions. In serious cases, we might need to have a inadequate heart valve transposed or repaired.
