2. Echocardiography - Wikipedia

   en.wikipedia.org/wiki/Echocardiography

   Sonographer doing an echocardiogram of a child Echocardiogram in the parasternal long-axis view, showing a measurement of the heart's left ventricle. Health societies recommend the use of echocardiography for initial diagnosis when a change in the patient's clinical status occurs and when new data from an echocardiogram would result in the physician changing the patient's care. [7]

3. Transthoracic echocardiogram - Wikipedia

   en.wikipedia.org/wiki/Transthoracic_echocardiogram

   A transthoracic echocardiogram (TTE) is the most common type of echocardiogram, which is a still or moving image of the internal parts of the heart using ultrasound. In this case, the probe (or ultrasonic transducer ) is placed on the chest or abdomen of the subject to get various views of the heart.

   An echocardiogram (echo), or diagnostic cardiac ultrasound, is a test that uses sound waves to create a picture of the heart in motion. It shows the shape and size of the heart and reveals how the ...

5. E/A ratio - Wikipedia

   en.wikipedia.org/wiki/E/A_ratio

   The E/A ratio is a marker of the function of the left ventricle of the heart. It represents the ratio of peak velocity blood flow from left ventricular relaxation in early diastole (the E wave) to peak velocity flow in late diastole caused by atrial contraction (the A wave). [1]

   Part C will also cover an echocardiogram, but you’ll typically need to stay within your plan’s network. If Medicare doesn’t cover your echocardiogram, even though you think it should, you ...

7. Left atrial volume - Wikipedia

   en.wikipedia.org/wiki/Left_atrial_volume

   The left atrial volume is commonly measured by echocardiography or magnetic resonance tomography.It is calculated from biplane recordings with the equation: = where A4c and A2c denote LA areas in 4- and 2-chamber views respectively, and L corresponds to the shortest long-axis length measured in either views.

8. Doppler echocardiography - Wikipedia

   en.wikipedia.org/wiki/Doppler_echocardiography

   Doppler echocardiography is a procedure that uses Doppler ultrasonography to examine the heart. [1] An echocardiogram uses high frequency sound waves to create an image of the heart while the use of Doppler technology allows determination of the speed and direction of blood flow by utilizing the Doppler effect.

9. Aortic valve area calculation - Wikipedia

   en.wikipedia.org/wiki/Aortic_valve_area_calculation

   For verification purposes of the obtained valve area using echocardiogram and doppler measures, especially if the obtained valve area is in the range requiring surgery and cardiac output is low, the Gold standard of left heart catheterization for true hemodynamics should be obtained for validation using the Gorlin formula, so patient does not ...
