How Reliable Is Echocardiogram
Depends: It depends on what you are trying to diagnosis. It is obviously of no use in diagnosing appendicitis. For leakage or a block in a heart valve it is very reliable. Same as for measuring how hard the muscle is contracting or whether the heart chambers are enlarged. It also depends on technical issues. Less reliable if you are 400 pounds or have lung disease.See 1 more doctor answer
Is american society of echocardiography a reliable source for echocardiogram reference values? Is that what most use as a source?
You bet!: Is the irs a reliable source of tax information? (hi, duck!) harvey and catharine have written the most widely used textbooks, but the ase (of which they are contributing members) writes the guidelines.See 1 more doctor answer
In an adult, is an echocardiogram likely to miss a small vsd (small, but causing a murmur)? Or is it reliable to rule it out? Usually found as child?
Unlikely: If we can hear the murmur with a stethoscope, then an echo probe will usually be able to show the blood crossing the vsd, even if the 2-d imaging doesn't clearly show the defect. However, if the echo windows are very poor (e.g., with obesity, chest wall deformities or fused ribs, lung disease like emphysema, etc.), then it may be hard to visualize the heart at all, and a vsd could then be missed.See 1 more doctor answer
Is echocardiogram more reliable than CT to diagnose cardiomegaly? Chest CT showed mild cardiomegaly but echocardiogram was oaky.
Echocardiogram: May give a better idea of how big your heart really is. That is because a CT is performed on your back, most of the time. That does tend to make the heart look larger. The echocardiogram is done on your back but also on the side. So my feeling is if the echocardiogram says you are normal then you are.See 1 more doctor answer
Several things: The heart muscle, the valves, arteries such as the aorta, the four chambers of the heart, fluid around the heart if present, how hard the heart is contracting, whether it is too weak or too thick.See 1 more doctor answer
Doppler effect: The echocardiogram utilizes ultrasound and a principle called the doppler effect. Doppler effect means sound waves are reflected at different velocities and this information is electronically transformed to allow visualization of structural details and provide information about blood flow velocities.See 1 more doctor answer
Not sure: What you mean. The ekg has two readings. The computer generated read is immediate and not always correct. Then an over read by a physician is made and agrees with or corrects and improves the accuracy of the reading. A wrong computer generated read is not a falsification but a weakness in the technology at this point.
Echocardiogram: This is a non-invasive heart examination with ultrasound much like an obstetric ultrasound study except that it is directed at the heart. It is generally painless and involves no radiation exposure. Of all cardiac studies, it probably tells us more about cardiac structure and function than any other cardiac test. Don't worry about having one done!See 1 more doctor answer
Ask your Doctor: Echocardiogram is an ultrasound exam of your heart. It looks at the heart valves, heart muscles, blood vessels, and how they function. The exam is used when the doctor things there may be a problem with your heart muscle, valves, or blood vessels. There are too many indications to list, but your doctor or a cardiologist can determine if you should get one.
Yes: As is the case with any test, if it is not done properly the results can be misleading. The technician doing the test has to have certain skills or the test can be misleading or just not of good enough quality to give the information being looked for. "garbage in, garbage out" they say.See 1 more doctor answer
Looks at heart: An echocardiogram uses sound waves (sonar) to look at the structure and function of the heart. The strength of the heart muscle, size of the various heart chambers and the structure and function of the heart valves is determined. Damaged heart from a heart attack can be seen any any valves that are narrowed (stenosed) or leaky are easily seen.See 1 more doctor answer
Ultrasound of heart: An echocardiogram is a type of ultrasound of the heart. Just like an ultrasound of a pregnant woman shows a real-time picture of the fetus, an echocardiogram shows a real-time picture of the heart. An echocardiogram can show if heart valves are abnormal, if the heart is thickened or dilated, how well the heart can pump, if there are any holes in the heart walls, and other heart problems.See 1 more doctor answer
