When to Take Echo Test: Do I Need an Echocardiogram?
Time to read 12 min
An echocardiogram (echo test) is a non-invasive heart ultrasound scan that uses high-frequency sound waves to create detailed images of the heart. Doctors may recommend an echo test if you experience chest pain, shortness of breath, rapid heartbeat, high blood pressure, heart failure symptoms, or suspected heart valve disease.
The test helps evaluate heart function, blood flow, heart valves, congenital heart defects, and other cardiovascular conditions.
According to the American Heart Association (AHA), echocardiography is one of the most commonly used color flow imaging tests for evaluating heart structure, heart valves, blood flow, and overall heart function.
Your cardiologist or general practitioner may recommend getting an echo test done if you are at a higher risk of developing cardiovascular issues or are experiencing the key signs.
If you experience symptoms such as chest pain, rapid heartbeat, shortness of breath, dizziness, or persistent cardiovascular concerns, consult a healthcare professional who can determine whether an echocardiogram is appropriate.
At MyDiagnostics, echocardiogram testing is performed using advanced cardiac imaging technology to help assess heart health accurately.
What does an Echocardiogram detect?
There are several medical reasons why an echo is used for assessing heart health and to help detect specific heart conditions and issues. These are as follows:
Potential heart failure
If you have an issue with optimal heart function, then an echocardiogram can detect or monitor heart conditions while helping doctors monitor heart health through a 2D scan. It can also show how well the heart is pumping blood and whether the heart muscle has been damaged or weakened.
The American Heart Association identifies fetal echocardiography as an important diagnostic tool for assessing heart failure, measuring ejection fraction, and evaluating how effectively the heart pumps blood throughout the body.
Detecting heart disease
If you have a history of cardiac issues, long-term high blood pressure, and are experiencing symptoms, then you can get a 2D echo to detect heart disease and evaluate the heart muscle and how well the heart is pumping blood. Echocardiograms are also used to check the ejection fraction of the heart and may be repeated as follow-up scans based on recovery needs.
The European Society of Cardiology (ESC) recommends echocardiography as a key imaging test for evaluating suspected cardiovascular disease, structural heart abnormalities, and heart valve disorders.
Birth defect in heart
Signs of birth defects within the heart, including congenital defects and congenital heart defects, can be detected with the fetal echocardiogram, and a doctor may also recommend one when evaluating heart disease related to long-term high blood pressure.
Heart attack damage
If you've gone through a myocardial infarction, then an echocardiogram can be used to review potential sites of damage to the heart valves and detect congenital heart defects, including structural defects present from birth.
Infection in the heart
The presence of endocarditis can be detected through the echocardiogram within the lining of the heart, and it may also show a pericardial effusion linked to inflammation or infection around the heart.
Issues with heart walls
If the patient has cardiomyopathy, then the test to detect it would be the echocardiogram. Any abnormalities affecting the heart walls can be evaluated using an echocardiogram. It also helps assess the heart's structure, the heart's chambers, the major blood vessels, and fluid around the heart, including pericardial effusion.
Your doctor will be able to provide all the necessary insights on what to expect during the test, as well as what aspects of heart function and blood flow are being evaluated. They may also inform you not to consume food or drinks for a few hours prior.
Can an Echo Test Detect Heart Blockage?
An echocardiogram cannot directly detect or visualize blockages in the coronary arteries. Tests such as coronary angiography or CT coronary angiography are typically used to identify the exact location and severity of arterial blockages.
However, an echocardiogram can detect the effects of reduced blood flow on the heart muscle. For example, a stress echocardiogram may reveal abnormal heart wall motion or reduced pumping function that could suggest coronary artery disease or a heart blockage affecting blood supply to the heart.
According to the American Heart Association (AHA), stress echocardiography is often used to evaluate symptoms that may be related to coronary artery disease and reduced blood flow to the heart.
Is an Echo Test Painful?
A standard transthoracic echocardiogram (TTE) is a non-invasive and painless procedure. During the test, a technician places a handheld device called a transducer on your chest to send high-frequency sound waves and create images of the heart. Most patients experience little to no discomfort.
A transesophageal echocardiogram (TEE), however, involves passing a thin probe through the oesophagus to obtain more detailed images of the heart. Patients may experience mild throat discomfort, but the procedure is generally safe and well-tolerated.
MyDiagnostics offers echocardiogram services that help evaluate heart function, blood flow, and valve abnormalities.
What Happens During an Echo Test?
A standard transthoracic echocardiogram (TTE) is a simple, non-invasive procedure that is usually completed within 30 to 60 minutes.
During the test:
You will lie comfortably on an examination table.
A cardiac sonographer will place a special gel on your chest.
A handheld device called a transducer will be moved across different areas of your chest.
The transducer sends high-frequency sound waves into the heart.
These sound waves create real-time images of the heart's chambers, valves, blood vessels, and blood flow.
The images are recorded and later reviewed by a cardiologist.
The procedure does not use radiation and is generally considered safe and painless.
How Long Does an Echo Test Take?
The duration of an echocardiogram depends on the type of test being performed.
Transthoracic echocardiogram (TTE): 30–60 minutes
Transesophageal echocardiogram (TEE): 45–90 minutes
Stress echocardiogram: 45–60 minutes
The procedure is usually completed on the same day, and most patients can resume their normal activities shortly afterwards.

Is Fasting Required Before an Echo Test?
Most standard transthoracic echocardiograms do not require fasting or any special preparation.
However, fasting may be necessary before a transesophageal echocardiogram (TEE). Your healthcare provider may ask you to avoid food and drinks for several hours before the procedure.
Always follow the instructions provided by your healthcare professional or diagnostic centre before undergoing the test.
Who Should Get an Echo Test?
Doctors may recommend an echocardiogram for individuals who have symptoms, risk factors, or medical conditions that could affect heart health.
You may need an echo test if you have:
Chest pain
Shortness of breath
Rapid or irregular heartbeat
Heart murmurs
High blood pressure
Swelling in the legs or ankles
Unexplained fatigue
A history of heart attack
Congenital heart defects
Suspected heart valve disease
A family history of certain heart conditions
An echocardiogram may also be recommended when ECG findings are abnormal or when further evaluation of heart function and blood flow is required.
When do I need an echocardiogram?
There are many instances wherein doctors would want to know the functioning of the heart from a visual perspective using the sound waves within an echo test.
An ECG may also not be enough to understand the core reason behind your chest pain or palpitations, and when cardiomyopathy is suspected, an echo test can analyze the heart’s structure, including the heart’s chambers and major blood vessels.
That's why healthcare professionals recommend getting a fetal echocardiogram done to rule out potential infections, damage, and other critical issues.
A healthcare provider can also use the results to guide treatment options and help you track your cardiac health over time, if you have been taking the right precautions and measures.
You may also want to get an echo test done as part of your annual examination or health check-up. It may help identify previously undetected structural abnormalities.
What Diseases Can an Echo Test Detect?
An echocardiogram can help diagnose or monitor a wide range of cardiovascular conditions, including:
Heart failure
Coronary artery disease
Cardiomyopathy
Heart valve disease
Congenital heart defects
Blood clots within the heart
Endocarditis
Pericardial effusion
Pulmonary hypertension
Enlargement of the heart chambers
Damage following a heart attack
Because the test provides detailed images of the heart's structure and function, it remains one of the most valuable tools for evaluating overall heart health.
Knowing the types of echocardiograms
There are three major types of echocardiograms, which vary in goals and function. A specialist may opt for all three types of echocardiograms when required. Your healthcare provider can explain which one you need and advise about medications beforehand.
Fasting is especially required for a transesophageal echocardiogram. Unlike an ECG, which records the heart's electrical activity, an echocardiogram shows the heart’s structure and function for medical professionals to interpret.
Transthoracic echocardiogram
The transthoracic echocardiogram (TTE) is the main ultrasound-based, noninvasive test for the heart, using sound waves to create real-time images and detailed images that help doctors assess its structure and function.
Unlike an ECG, which mainly checks the heart’s electrical activity, this test is often ordered when medical professionals need to evaluate chambers, valves, blood flow, or other structural concerns. A detected heart murmur or concerning symptoms in athletes may also prompt an echocardiogram.
Transesophageal echocardiogram
A transthoracic echocardiogram is the most common type and a noninvasive test, while a transesophageal echocardiogram (TEE) uses a probe passed through the oesophagus when more detailed internal views are needed.
It creates real-time, detailed images to assess the heart’s structure and function without radiation exposure, and in some cases, a contrast dye is used to improve image quality.
The TEE test may be recommended for some patients to detect blood clots and infections, and while it may cause mild discomfort, patients should also be aware that serious complications are rare. A standard echocardiogram usually takes about 30 to 60 minutes.
Stress echocardiogram
In a transesophageal echocardiogram (TEE), a thin probe is guided into the oesophagus to give more detailed internal views when needed. It may be used for better views of structures such as clots, may involve mild discomfort, and stress echo testing can also help detect coronary artery disease by showing how the heart works under exertion.
Throat soreness can occur afterwards, serious complications are rare, and you may need to arrange a ride home.
Understanding the core symptoms of heart issues
There are several symptoms of cardiac issues and complications that you shouldn't ignore, especially when they may affect overall heart health.
The risk increases significantly if you have a prior history of cardiac issues as well, and follow-up imaging may also be used to monitor valve disease over time. Some of the major signs are as follows.
Chest pain
You shouldn't ignore chest pain over time, as it can be a significant indicator of a cardiac issue. Consult a healthcare provider if symptoms persist.
Rapid heartbeat
A higher-than-normal heartbeat can be an important sign that you need an echo test done. You should consult with a cardiologist or get an ECG and an echo test performed quickly.
Headaches and dizziness
Headaches and dizziness can occur for many reasons. When accompanied by symptoms such as chest pain, palpitations, shortness of breath, or abnormal blood pressure, further cardiac evaluation may be recommended.
Complications with blood pressure
If you have issues with blood pressure, wherein it may suddenly rise or fall, then you should get a complete echocardiogram test done. A TMT test may also be beneficial for you as well.
Difficulty breathing
You may find it more difficult to breathe after walking or jogging, and it is an important sign that you shouldn't ignore if you do have a history of cardiac issues. A Doppler echocardiogram measures blood flow and pressure in the heart when blood pressure-related concerns are being checked, especially if you also notice shortness of breath.
According to the World Heart Federation, cardiovascular disease remains the leading cause of death worldwide. Early evaluation of symptoms such as chest pain, shortness of breath, palpitations, and unexplained fatigue can help detect heart conditions sooner and support timely treatment decisions.
Echo Test Cost
The cost of an echocardiogram varies depending on the type of test, location, healthcare facility, and additional imaging requirements. A standard transthoracic echocardiogram generally costs less than specialised tests such as stress echocardiography or transesophageal echocardiography.
Patients should consult their healthcare provider or diagnostic centre to obtain accurate pricing information based on their specific requirements.
Conclusion
Knowing when to take an echo test can help detect heart problems before they become serious. An echocardiogram is a safe, non-invasive imaging test that uses high-frequency sound waves to evaluate heart function, blood flow, heart valves, and the overall structure of the heart.
Healthcare professionals may recommend an echo test if you experience symptoms such as chest pain, shortness of breath, rapid heartbeat, dizziness, or unexplained fatigue, or if you have risk factors such as high blood pressure, heart disease, or a family history of cardiac conditions.
Whether it is used to diagnose heart failure, congenital heart defects, valve disorders, cardiomyopathy, or damage after a heart attack, an echocardiogram provides valuable insights into your heart health.
At MyDiagnostics, advanced echocardiography services help patients receive accurate cardiac assessments and timely medical guidance. If you have persistent cardiac symptoms or concerns about your cardiovascular health, consult your healthcare provider to determine whether an echo test is right for you.
