Heart Murmur (Definition)

A heart murmur is a sound heard by a stethoscope made by the vibration of blood flow. It can be a normal finding in young healthy people, or can represent abnormal leakage (regurgitation) of a valve, valve narrowing (stenosis), or a congenital condition such as an atrial septal defect, a ventricular septal defect, ...Read more

Varies: The intensity of the murnur can vary depending on various patient factors, including the precise location of the defect in the wall, the size of the patient, the pressure on the right side of the heart, etc. However, a restrictive vsd will usually produce a prominent murmur. ...Read more

What are holosystolic murmurs?

What are holosystolic murmurs?

Sounds...: Classically, a vsd results in increased blood flow from left to right ventricle due to pressure differences and results in a holosystolic murmur. This means that the murmur begins with the av valves closing and ends with the aortic/pulmonic valves closing (phase known as systole). ...Read more

How come we got diastolic murmurs?

How come we got diastolic murmurs?

Diastolic murmurs: Flow occurs during ventricular diastole as the ventricles fill. Abnormal mitral/tricuspid stenosis can produce such a murmur with impaired diastolic filling, while regurgitation across the aortic/pulmonary valves can accentuate flow into ventricles also producing a murmur. ...Read more

What is a neck murmur?

Bruit: A murmur that arises in a blood vessel (instead of the heart) is called a bruit (pronounced "brew-eee"). It is due to turbulence, usually from a blockage. In the neck, the culprit is the carotid artery. ...Read more

What is an end-systolic murmur?

Probable MVP: Mitral valve prolapse- a relatively benign abnormality- classically has a physical exam which includes a late systolic click followed by a murmur. My best guess is that is what an end-systolic murmur refers to. ...Read more

What is the systolic in systolic murmur?

What is the systolic in systolic murmur?

Pumping Time!: The ventricles of the heart pump blood to the lungs and to the rest of the body. The portion of the cardiac cycle where they fill with blood is known as diastole. The portion where they contract to push that blood forward is known as systole. A murmur which occurs during this portion of the cardiac cycle is known as a systolic murmur. ...Read more

Will an X-ray tell you if you have a murmur?

Murmurs are sounds: No, an X-ray cannot identify a heart murmur. Heart murmurs are abnormal sounds heard during your heartbeat cycle that are made by turbulent blood in or near your heart. These sounds can be heard with a stethoscope. ...Read more

What disease is caused by holosystolic murmurs?

What disease is caused by holosystolic murmurs?

Murmurs: Holosystolic murmurs are heart sounds associated with insufficiency of the atrioventricular valves and ventricular septal defects. There are other possible holosystolic murmurs but these are the bulk of them. The murmur is purely sound and causes no problem. The physiologic problem causing the sounds is what causes the problem. ...Read more
