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

25 yr. No symptoms. Faint murmur. Normal echo, ekg. Told innocent. Vsd unlikely?

25 yr. No symptoms. Faint murmur. Normal echo, ekg. Told innocent. Vsd unlikely?

Unlikely: An normal thorough echocardiogram, especially a pediatric echo, generally rules out a vsd. It would be very unlikely to fail to identify a significant vsd on a thorough echo. Tiny ones can sometimes be missed, but they usually don't matter anyway since they rarely cause problems or need treatment. ...Read more

Heart murmur with normal echocardiogram. Only showed trace mitral & tricuspid valve regurgitation. Does this mean murmur is benign?

Heart murmur with normal echocardiogram. Only showed trace mitral & tricuspid valve regurgitation. Does this mean murmur is benign?

Yes: A murmur is just a sound made by blood flowing through your heart and valves. If the Echo is normal, trace mitral and tricuspid regurgitation is probably normal for you. Benign means not indicative of pathology or not pathological. You have a benign murmur. ...Read more

Why is aortic valve sound heard much easier than mitral valve using stethoscope?

Why is aortic valve sound heard much easier than mitral valve using stethoscope?

Heart sounds: the aortic sounds are louder because they are caused by higher pressures and the valve is closer to the chest wall ...Read more

When listening to my heart with a stethescope, my heartbeat sounded like, "woosh'dub, whoosh'dub." instead of normal "lubb'dubb" sound. Why?

When listening to my heart with a stethescope, my heartbeat sounded like, "woosh'dub, whoosh'dub." instead of normal "lubb'dubb" sound. Why?

Murmur: Could be a murmur....Get an echocardiogram & talk to your physician (in opposite order) but in a young person may be a normal systolic flow murmur. ...Read more

Does a murmur from pulmonary stenosis sound different than an innocent murmur?

Does a murmur from pulmonary stenosis sound different  than an innocent murmur?

Pulmonary stenosis: Many innocent murmurs are flow through the pulmonary artery because it is close to the chest wall. Actual pulmonary valve stenosis has associated findings which help identify it on physical exam in addition to the murmur. The actual murmur may be somewhat similar. When a question exists echocardiography generally will answer the question. ...Read more

Diastolic murmur aortic regurgitation. Is this bad?

Diastolic murmur aortic regurgitation. Is this bad?

Yes: How bad depends on regurgitant fraction, left ventricular dimension, ejection fraction, pulmonary pressures. Echocardiogram and cardiac cath. Needed to assess for correction. ...Read more

Can a holosystolic murmur be functional- innocent if echocardiogram is normal?

No: Holosystolic murmurs are not normal. If the echocardiogram is read as normal, either you don't have a holosystolic murmur, or the echocardiogram missed the abnormality causing the murmur. If the echocardiogram is truly normal, it is morst likely that you have a systoli ejection murmur, not a holostysolic murmur. Innocent, or normal heart murmurs, are typically systolic ejection murmurs. ...Read more

Friend 32male is overweight with skipping pulse beat, loud heart beat and skipped heart beat. What's wrong?

Friend 32male is overweight with skipping pulse beat, loud heart beat and skipped heart beat. What's wrong?

Irregular heartbeat: An irregular pulse is usually due to irregular heartbeat which in turn is often due to benign variation in electrical activity of the heart. This is particularly true if not accompanied by other cardiac symptoms, progressive nature or exertional symptoms. However, an ekg is appropriate and required if any other symptoms are present. ...Read more

I have mitral valve prolapse plus a heart murmur, is this normal.?

I have mitral valve prolapse plus a heart murmur, is this normal.?

MVP: Mitral valve prolapse is an abnormality of this heart valve which can be associated with a heart murmur, chest pain or heart arrhythmia. The valve is abnormal and 'flops' into the atrium. It may or may not be associated with a murmur which is the valve leaking. Worst case is that it is a syndrome associated with arrhythmias and even strokes. It should be followed by a cardiologist. ...Read more

Dr. could hear a murmur- did EKG showed shortened pr interval, echo showed trace mitral, tricuspid & pulmonic insuffiency everything else normal?

Dr. could hear a murmur- did EKG showed shortened pr interval, echo showed trace mitral, tricuspid & pulmonic insuffiency everything else normal?

Echo unremarkable: Trace insufficiency is common and typically is an incidental finding. If you are not symptomatic then I would not be concerned. The short PR can be normal, and also is typically not an issue unless you are having fast heart rates or the ECG showed risk for a fast heart rate. ...Read more

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

Ekg left atrial enlargement, nonspecific t wave abnormality, echo done trace mitral regurg, tricuspid regurg. Pericardial effusion global.Is my heart ok?

Ekg left atrial enlargement, nonspecific t wave abnormality, echo done trace mitral regurg, tricuspid regurg. Pericardial effusion global.Is my heart ok?

More info needed: I am assuming echo is showing pericardial effusion and global? Or maybe global hypohypokinesia? Any wall motion abnormalities? Ejection fraction? Do u have any symptoms? At rest or with activities? Any other risk factors? Smoker, overweight, dm, htn, high chol, family history heart attacks, sedentary life etc. Any prior heart attacks? Stress test done. Any recent viral infection? Pericarditis? ...Read more

At 5yr old heart murmur, normal echo @7yrs chest pain, heartrate 61, normal 24 hr holster, abnormal ecg pointing to lvh. Whats goin on?!?

Chest pain: The reason for the chest pain is not probably cardiac. Other causes like acid reflux or musculsketal chest pain that could cause it. The LVH on the echo doesn't mean anything. ...Read more

What is benign heart murmur?

What is benign heart murmur?

Common, not serious: Heart murmur is basically an extrasound is heard/generated when the heart pumps. Benign in medicine means not serious/not concerning. Probably about 60% of young children have some murmur during the first decade of life because of the rapid changes in the heart as they grow. So, if doc said benign heart murmur, that is something not to worry. If u are still concerned, consult doc. Good luck. ...Read more

ECHO: Normal Left ventricular size + wall thickness and wall motion, Normal biventricular systolic function, Mild MVP w/ trace regurgitation, EF 67%, RV systolic pressure 16mmHg, mild heart murmur. No symptoms. Help! Is this normal?

ECHO: Normal Left ventricular size + wall thickness and wall motion, Normal biventricular systolic function, Mild MVP w/ trace regurgitation, EF 67%, RV systolic pressure 16mmHg, mild heart murmur. No symptoms. Help! Is this normal?

MVP: Your echocardiogram is not perfectly normal as it shows mild mitral valve prolapse. All other parameters are normal. MVP is very common and very often causes no problems. Nevertheless I recommend periodic follow-up by a cardiologist as the mvp can worsen, cause atrial arrhythmias and atypical chest discomfort. Very often a click can be heard on stethoscope examination of the heart. ...Read more

Plz xplainEcho says EF 60% Mild mitral valve prolapse.Left Atrium mildly dilated.mild mitral regurg.cannot rule out bicuspid aortic valve considerTEE?

Had a cath?: The echo says there might be a structural abnormality of the aortic valve and a leak of the mitral valve with resultant dilation of left atrium. If you had the cardiac cath you list any time recently, more information should be available from that. A TEE is a transesophageal echo which gives us better pictures than a transthoracic echo. You should discuss this echo with your Doc ...Read more
