2D Echocardiography Transthoracic Echocardiogram with Volume and Area Measurements
This test uses ultrasound waves to create images of your heart’s structure and function. It measures specific areas and volumes within the heart chambers to assess heart health, blood flow, and potential abnormalities.
["This test helps doctors evaluate heart function and detect issues like enlarged chambers or abnormal blood flow patterns."]

What This Test Measures
The test evaluates key anatomical measurements, including left and right ventricular volumes and areas, to determine chamber sizes and wall motion. It may also assess diastolic function and detect structural abnormalities like hypertrophic cardiomyopathy or dilated cardiomyopathy.
How the Test Works
Ultrasound waves are directed at your chest, producing real-time images of your heart. The technician measures specific areas (e.g., left ventricular end-diastolic area, right ventricular area) and calculates volumes (e.g., left ventricular end-diastolic volume) using standard echocardiographic formulas.
Common Uses
This test is often used to diagnose or monitor conditions such as heart failure, valvular disease, congenital heart defects, and cardiomyopathies. It may also guide treatment decisions or assess recovery after heart surgery or interventions.
Preparation
No special preparation is needed. Wear comfortable clothing without buttons or zippers near the chest. You may be asked to remove jewelry or a belt. Lie on your back on an exam table, and a gel is applied to your chest to improve the ultrasound image quality.
Reference range
Non-smokers: <2.5 ng/mL; Smokers: <5.0 ng/mLN/A
No special preparation required. For PSA, avoid sexual activity for 24-48 hours before the test.
