  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.

  3. 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 .

  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.

  5. 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.

  6. E/A ratio - Wikipedia

    en.wikipedia.org/wiki/E/A_ratio

    Heart rate and rhythm - loss of a normal atrial rhythm (e.g., atrial fibrillation causes loss of the A wave). The height of the E wave becomes dependent on the length of the cardiac cycle (variable) rather than a measure of diastolic function. Similarly, pacing and tachycardia result in alterations, whereas bradycardia increases the E/A ratio.

  7. 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 ...

  8. Intracardiac echocardiogram - Wikipedia

    en.wikipedia.org/wiki/Intracardiac_echocardiogram

    Intracardiac echocardiography (ICE) is a specialized form of echocardiography that utilizes an ultrasound-tipped catheter to perform imaging of the heart from within the heart. Unlike transthoracic echocardiography (TTE), ICE is not limited by body habitus. An ICE catheter is inserted into the body, typically, through the femoral vein and ...

  9. Heart - Wikipedia

    en.wikipedia.org/wiki/Heart

    An echocardiogram is an ultrasound of the heart used to measure the heart's function, assess for valve disease, and look for any abnormalities. Echocardiography can be conducted by a probe on the chest (transthoracic), or by a probe in the esophagus (transesophageal).
