2. 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 ...

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. 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.

5. 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 ...

6. 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.

7. Valve of inferior vena cava - Wikipedia

   en.wikipedia.org/wiki/Valve_of_inferior_vena_cava

   The eustachian valve is frequently seen with transthoracic echocardiography from the parasternal long axis, the apical four-chamber and the sub-costal four-chamber views. The eustachian valve is better seen with transesophageal echocardiography in the bi-caval view and right sided horizontal and longitudinal views.
