An echocardiogram is a medical test that uses ultrasound to create images of the heart. A technician typically performs the test in a hospital or clinic setting. A physician uses an echocardiogram, a non-invasive method, to evaluate the heart’s structure and function. Here is more information on using echocardiograms in diagnostics:
Uses High-frequency Sound Waves
This test uses high-frequency sound waves to generate live images. The transducer sends sound waves into the body, and the sound waves reflect off heart structures. A clear gel is applied to the skin to facilitate the transmission of sound waves from the transducer into the body. A computer processes these returning echoes to create a detailed picture of the heart in motion.
Provides Detailed Information
Various types of echocardiograms exist, each designed to address specific clinical questions. Some methods may use a transducer that is placed on your chest wall. Others provide clearer images because they involve passing a probe down your throat to assess heart function during exercise. One technique measures the speed and direction of blood flow within the heart.
The images allow for precise measurements of cardiac structures. An echocardiogram assesses chamber size and wall thickness, and it calculates the ejection fraction. The ejection fraction is a percentage that shows how much blood the left ventricle pumps out with each contraction. Your doctor gets a comprehensive view of heart muscle and valve performance through these metrics.
Sonographers acquire images from specific locations on the chest to create standard views. One view shows the left ventricle, and the four-chamber view displays all four heart chambers at once. Although the test is efficient, image quality may be limited by factors such as lung disease or body shape.
Penetrates Body Tissues
Sound waves must travel through various body tissues to reach the heart. The frequency of the sound waves affects how deeply they penetrate tissue, so the sonographer adjusts settings to get the best possible images. Lower frequencies go deeper into the subject but result in less detailed images.
Certain conditions may interfere with the transmission of sound waves. For some, excess body fat or lung conditions like COPD can make it difficult to obtain clear pictures. In situations where standard images are unclear, a contrast agent may be injected into a vein to enhance the view of the heart’s chambers.
Diagnoses Symptoms
Your healthcare provider may recommend an echocardiogram if you experience symptoms such as shortness of breath, chest pain, or palpitations. The test helps identify the underlying cause of these symptoms by showing how your heart is working. It provides your doctor with a direct view of the heart’s pumping action and valve function. The findings from the test guide further medical decisions and treatment planning, and potential findings include:
- Leaky or narrowed heart valves
- Weakened heart muscle
- Fluid around the heart
Schedule an Echocardiogram Today
An echocardiogram provides valuable information about your heart’s health. You can speak with a cardiologist or your primary care provider to determine if this procedure is appropriate for you. To schedule an appointment, contact a qualified cardiology clinic, and make sure you have all the necessary information ready.
