2. Doppler echocardiography - Wikipedia

   en.wikipedia.org/wiki/Doppler_echocardiography

   3-052. [edit on Wikidata] 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.

3. Echocardiography - Wikipedia

   en.wikipedia.org/wiki/Echocardiography

   Echocardiography. Three-dimensional echocardiogram of a heart viewed from the apex. Echocardiography, also known as cardiac ultrasound, is the use of ultrasound to examine the heart. It is a type of medical imaging, using standard ultrasound or Doppler ultrasound. [1] The visual image formed using this technique is called an echocardiogram, a ...

4. 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. It is used as a non-invasive assessment of ...

5. Doppler ultrasonography - Wikipedia

   en.wikipedia.org/wiki/Doppler_ultrasonography

   Doppler echocardiography is the use of Doppler ultrasonography to examine the heart. [13] An echocardiogram can, within certain limits, produce an accurate assessment of the direction of blood flow and the velocity of blood and cardiac tissue at any arbitrary point using the Doppler effect. One of the limitations is that the ultrasound beam ...

6. Medical ultrasound - Wikipedia

   en.wikipedia.org/wiki/Medical_ultrasound

   Doppler echocardiography is the use of Doppler ultrasonography to examine the heart. [62] An echocardiogram can, within certain limits, produce accurate assessment of the direction of blood flow and the velocity of blood and cardiac tissue at any arbitrary point using the Doppler effect.

7. Tissue Doppler echocardiography - Wikipedia

   en.wikipedia.org/.../Tissue_Doppler_echocardiography

   Tissue Doppler echocardiography (TDE) is a medical ultrasound technology, specifically a form of echocardiography that measures the velocity of the heart muscle (myocardium) through the phases of one or more heartbeats by the Doppler effect (frequency shift) of the reflected ultrasound. The technique is the same as for flow Doppler ...

8. E/A ratio - Wikipedia

   en.wikipedia.org/wiki/E/A_ratio

   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] It is calculated using Doppler echocardiography, an ...

9. Cardiac imaging - Wikipedia

   en.wikipedia.org/wiki/Cardiac_imaging

   Apical four chamber ultrasound view of heart. Transthoracic echocardiography (TTE) uses ultrasonic waves for continuous heart chamber and blood movement visualization. It is the most commonly used imaging tool for diagnosing heart problems, as it allows non-invasive visualization of the heart and the blood flow through the heart, using a technique known as Doppler.
