Understanding the test
What is 2D echocardiography?
Two-dimensional echocardiography, commonly called a 2D Echo, is a diagnostic ultrasound test that creates moving images of the heart. A small handheld probe called a transducer is placed on the chest to send and receive high-frequency sound waves.
The images help the cardiology team assess the size and movement of the heart chambers, the pumping action of the heart muscle, the opening and closing of the valves, and the direction and speed of blood flow. Colour Doppler, spectral Doppler and M-mode measurements may also be used when clinically required.
01
Heart structure
Reviews chambers, walls, valves and major connected vessels.
02
Pumping function
Assesses heart-muscle movement and overall pumping performance.
03
Blood flow
Doppler imaging helps identify abnormal flow, narrowing or leakage.
Important: A standard 2D Echo is different from an ECG. An ECG records the electrical activity of the heart, while an echocardiogram shows the heart’s structure, movement and blood flow.
Clinical evaluation
What can a 2D Echo evaluate?
The examination provides important information about heart anatomy and function. The exact measurements and views depend on age, symptoms, medical history and the clinical question.
Pumping function
Assesses how strongly the heart contracts and may include calculation of left ventricular ejection fraction.
Heart valves
Evaluates valve structure and movement and helps identify narrowing (stenosis) or backward leakage (regurgitation).
Blood flow
Doppler imaging helps assess the direction and velocity of blood through valves, chambers and major vessels.
Congenital defects
Helps evaluate structural differences present from birth, including suspected abnormal connections or openings.
Fluid and pressure
Can identify fluid around the heart and may estimate pressures related to pulmonary hypertension.
Age-specific cardiac imaging
Adult, pediatric and neonatal echocardiography
The basic technology is ultrasound, but the examination is adapted to the patient’s age, body size, heart rate, symptoms and clinical condition.
Adult 2D Echocardiography
Used to evaluate symptoms and monitor known heart conditions, including valve disease, heart failure, cardiomyopathy and the effects of high blood pressure.
- Breathlessness, chest discomfort or swelling
- Heart murmur or suspected valve disease
- Reduced heart pumping or previous heart attack
- Cardiomyopathy and pulmonary hypertension
- Follow-up after cardiac treatment or procedures
Pediatric Echocardiography
A specialised examination for infants, children and adolescents. Measurements and interpretation consider the child’s age, height, weight and developing heart.
- Heart murmur or abnormal heart sounds
- Fainting, palpitations or exercise-related symptoms
- Poor growth, fast breathing or easy tiredness
- Suspected or known congenital heart disease
- Follow-up after congenital heart treatment
Neonatal Echocardiography
Used when a newborn requires detailed assessment of heart structure, function, circulation or the cardiovascular changes that occur after birth.
- Low oxygen levels or bluish discoloration
- Breathing difficulty or poor feeding
- Abnormal heart sounds, pulses or blood pressure
- Suspected congenital heart defect or PDA
- Assessment of pulmonary pressure or unstable circulation
Newborn and complex pediatric examinations require age-appropriate imaging protocols and specialist interpretation. Please confirm service availability and any feeding or timing instructions while booking.
When doctors may recommend it
Common reasons for a 2D Echo
An echocardiogram may be advised because of symptoms, physical examination findings, an abnormal ECG or X-ray, a known cardiac condition, or the need for treatment follow-up.
01Shortness of breath or reduced exercise capacity
02Chest discomfort, fainting or unexplained weakness
03Palpitations or an abnormal heart rhythm
04Heart murmur or suspected valve problem
05Leg swelling or possible heart failure
06High blood pressure with possible heart changes
07Known congenital or structural heart condition
08Monitoring before or after cardiac treatment
Simple and non-invasive
What happens during the test?
A standard transthoracic echocardiogram is performed from the outside of the chest. It does not involve surgery or a tube passing into the body.
Clinical details
Your symptoms, medical history and the reason for the test are reviewed.
Positioning
You lie on an examination bed, usually on your back or left side.
Gel and probe
Water-based gel is applied and the ultrasound probe is moved over the chest.
Images and Doppler
Multiple views and measurements are recorded while you breathe normally or briefly hold your breath.
Review and report
The findings are interpreted in the context of your symptoms and other clinical information.
Before and after the scan
Preparation, comfort and safety
How to prepare
- Fasting is usually not required for a standard transthoracic 2D Echo.
- Continue regular medicines unless your treating doctor gives different instructions.
- Wear comfortable clothing and be prepared to expose the chest for accurate probe placement.
- Bring previous Echo reports, ECGs, prescriptions, discharge summaries and relevant scans.
- For babies and young children, ask the clinic whether feeding, sleep or comfort measures are recommended before arrival.
Safety and recovery
- The test uses sound waves and does not expose the patient to X-rays or ionising radiation.
- It is usually painless, although gentle pressure from the probe may occasionally feel uncomfortable.
- No injection is normally required for a routine 2D Echo. Contrast Echo is used only in selected situations.
- Most patients can return to their normal activities immediately after the examination.
- The test may take longer when detailed congenital views are needed or when a baby or child requires extra time to settle.
Understanding the report
Common terms in a 2D Echo report
An echocardiogram contains many measurements. A single number should not be interpreted alone; the complete report must be matched with symptoms, examination findings and other tests.
An estimate of the percentage of blood pumped out of the left ventricle with each contraction.
Describes whether the atria or ventricles appear normal in size or enlarged.
Shows whether different areas of the heart muscle contract normally.
Narrowing of a heart valve that can restrict forward blood flow.
Backward leakage of blood through a valve that does not close completely.
Fluid collected in the sac surrounding the heart.
How the heart muscle relaxes and fills with blood between beats.
An estimate that may help assess increased pressure in the lung circulation.
Terms used for certain abnormal connections or openings associated with congenital heart disease.
A resting 2D Echo does not directly show every coronary artery blockage. It may reveal effects such as abnormal wall movement or reduced pumping. Additional testing may be recommended when coronary artery disease is suspected.
When more information is needed
Possible additional cardiac investigations
Depending on the clinical findings, a cardiologist may recommend another test to answer a specific question that a routine 2D Echo cannot fully address.

Patient questions
Frequently asked questions
Clear answers to common questions about adult, pediatric and neonatal 2D echocardiography.
Is a 2D Echo painful?
A standard transthoracic 2D Echo is usually painless. You may feel mild pressure when the probe is pressed against the chest to obtain clear images, especially between the ribs.
Does an echocardiogram use radiation?
No. It uses ultrasound waves rather than X-rays, so there is no exposure to ionising radiation during a routine echocardiogram.
Do I need to fast before a 2D Echo?
Fasting is generally not required for a standard transthoracic Echo. Fasting instructions may apply to other tests, such as transesophageal echocardiography or certain stress studies, so follow the specific instructions provided for your appointment.
How long does the test take?
A routine adult study commonly takes about 20–40 minutes. Complex valve or congenital examinations may take longer. Pediatric and neonatal scans may also require additional time for detailed views or to help the child settle.
Can a 2D Echo detect heart blockage?
A resting 2D Echo does not directly display every blockage in the coronary arteries. It can show changes that may result from reduced blood supply, such as abnormal heart-muscle movement or reduced pumping. Tests such as stress imaging, CT coronary angiography or coronary angiography may be needed when blockage is suspected.
What is ejection fraction?
Ejection fraction is an estimate of how much blood the left ventricle pumps out with each contraction. It is one part of the report and should be interpreted along with chamber size, valve function, symptoms and other findings.
Why has my child been advised an echocardiogram?
Common reasons include a heart murmur, symptoms such as fainting or poor growth, an abnormal ECG, a family history of heart disease, suspected congenital heart disease, or follow-up of a known cardiac condition.
Is echocardiography safe for a newborn baby?
Echocardiography uses ultrasound and does not involve radiation. Newborn examinations should be performed using age-appropriate protocols, with the findings interpreted by clinicians trained in neonatal or pediatric cardiac assessment.
Can a parent stay with the child during the test?
In many outpatient settings, a parent or caregiver may remain nearby to reassure the child. The exact arrangement depends on the facility, the child’s age and the clinical situation.
Will I need another test after the Echo?
Not always. Additional testing is recommended only when the doctor needs more information about rhythm, blood supply, detailed valve anatomy, coronary arteries or another specific concern.
