  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.

  3. Ejection fraction - Wikipedia

    en.wikipedia.org/wiki/Ejection_fraction

    Modalities applied to measurement of ejection fraction is an emerging field of medical mathematics and subsequent computational applications. The first common measurement method is echocardiography, [7] [8] although cardiac magnetic resonance imaging (MRI), [8] [9] cardiac computed tomography, [8] [9] ventriculography and nuclear medicine (gated SPECT and radionuclide angiography) [8] [10 ...

  4. 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]

  5. Tissue Doppler echocardiography - Wikipedia

    Age dependent normal values for S', e' and a'. The e'/a' ratio becomes <1 about 60 years of age, which is similar to the E/A ratio of mitral flow. Women has slightly higher S' and e' velocities than men, although the difference disappears with age.

  6. 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.

  7. Pericardial effusion - Wikipedia

    en.wikipedia.org/wiki/Pericardial_effusion

    An echocardiogram is urgently needed for evaluation when there is concern for hemodynamic compromise, a rapidly developing effusion or history of recent cardiac surgery/procedures. [ 1 ] Cardiac CT and MRI scans: cross-sectional imaging with computed tomography (CT) can help localize and quantify the effusion, especially in a loculated effusion ...

  8. Speckle tracking echocardiography - Wikipedia

    en.wikipedia.org/wiki/Speckle_Tracking...

    In the fields of cardiology and medical imaging, speckle tracking echocardiography (STE) is an echocardiographic imaging technique. It analyzes the motion of tissues in the heart by using the naturally occurring speckle pattern in the myocardium (or motion of blood when imaged by ultrasound ).

  9. Left ventricular mass - Wikipedia

    en.wikipedia.org/wiki/Left_ventricular_mass

    Published normal ranges for LVMi are 49–115 g/m 2 for men and 43–95 g/m 2 for women. [1] [4] left ventricular hypertrophy (LVH) is defined as an abnormal increase in LVM, an important independent risk factor for cardiovascular morbidity and mortality.
