Did you know that one in three adults older than 40 years suffers from some heart issues and undergoes heart tests such as an ECG or echocardiogram, at least once a year? These are crucial methods of diagnosing heart issues at an early stage when the symptoms are not severe or non-existent. However, many people are confused and often wonder about the differences between an ECG and an Echocardiogram.
This guide will help you understand the differences between an ECG and an Echocardiogram, and when you use them.
What Is an ECG (Electrocardiogram)?
An electrocardiogram or ECG is a painless and rapid test used to determine the electrical activity in your heart. Small electrodes are put on your chest, arms, and legs to record and detect the heart rhythm.
ECG helps to determine abnormal heartbeats (arrhythmias), heart attacks, and electrical conduction problems. ECG test normally requires approximately 5-10 minutes and is commonly the initial screening procedure conducted on a patient having chest pain, palpitations, or shortness of breath.
What Is an Echocardiogram (Echo Test)?
An echocardiogram (echo) is a test that involves the use of an ultrasound wave to produce real-time images of your heart. It enables the physicians to view the chambers, valves, and the strength of the heart’s pump.
In comparison to an ECG, an echo test provides structural and functional information, a measure of the efficiency of the heart muscle and valves. The echo test is usually done for heart murmurs, heart failure symptoms, and to check for blockages in the heart valves.
ECG vs Echocardiogram: Key Differences
When comparing ECG vs echocardiogram, the main distinction lies in what they measure:
- ECG (Electrocardiogram): Checks electrical activity and rhythm.
- Echo (Echocardiogram): Shows physical structure and blood flow.
| Aspect | ECG (Electrocardiogram) | Echo (Echocardiogram) |
| Purpose | Measures the heart’s electrical signals | Visualises heart structure and function |
| Duration | 5-10 minutes | 20-45 minutes |
| Procedure | Uses electrodes on the skin | Uses ultrasound imaging |
| Detects | Arrhythmias, heart attack signs | Valve issues, heart muscle weakness |
| Invasiveness | Non-invasive | Non-invasive |
| Cost (India) | ₹200-₹800 | ₹1500-₹4000 |
When Is ECG Recommended?
An ECG test is usually recommended when you experience:
- Pain or tightness in the chest.
- Palpitation or abnormal heartbeats.
- Lightheadedness or fainting.
- Unexplained fatigue.
- Hypertension or diabetes.
An ECG can be included with an annual health check-up, particularly for people over 40 years or people with a family history of heart disease.

When Is an Echocardiogram Recommended?
An echocardiogram is useful if you have:
- Murmur of the heart or valve issues.
- Breathlessness or edema of the legs.
- Suspected heart failure.
- Congenital heart defects.
- After a heart attack.
Echocardiograms are able to identify abnormalities that would otherwise be missed by the ECG, which include valve stenosis or a weakened heart muscle.
ECG vs Echo: Which Test Is Better for You?
The echo test and the ECG are complementary to each other.
- Choose ECG when it is necessary to identify a problem with rhythm or the risk of a heart attack.
- Choose an Echo to test the structure, valve performance, and general functionality of the heart.
ECG and Echo Together: Why Doctors Suggest Both
In some cases, an ECG combined with an echocardiogram helps to provide the best diagnosis.
- ECG is capable of detecting irregular patterns in the heart.
- Echo unveils the consequences of those abnormalities by providing a 3D view of the heart.
This dual method assists the doctor in deciding whether the issue with the heart is electrical, muscular, or a combination of both. Particularly, it is necessary with chronic heart disease, diabetes, or high cholesterol.
When Should You Get an ECG or Echo Test?
Doctors may suggest an ECG or an Echo if you are experiencing:
- Regular chest discomfort/ shortness of breath.
- A-fibrillation or arrhythmia.
- Pitting oedema of legs or ankles.
- Unexplained fatigue or drowsiness.
- Have a history of heart disease or strokes.
If you observe any of these symptoms, it is necessary to consult a medical professional. You can book an online doctor consultation or book a lab test for an Echo or EKG based on what your doctor prescribes.
Cost and Availability of ECG & Echo Tests in India
Both tests are readily found in hospitals, diagnostic labs, and clinics in India. The prices of EKG or Echo vary based on several factors, such as location (rural or urban) and the type of hospital or diagnostic center.
- ECG: ₹200-₹800
- Echocardiogram: 1500-4000 (depending on the place and facility)
There are even clinics that provide home ECG services, which is convenient for the elderly or heart patients.

How to Prepare for ECG and Echocardiogram
If you have an ECG or Echo scheduled, here are some tips before you leave your house.
- ECG: Wear loose clothes, do not put lotions or oils on the chest.
- Echo: No special preparation, except wear a costume where the chest can be readily reached.
In case you are using heart or blood pressure medication, make sure to inform your doctor prior to taking the test.
Interpreting Your Test Results
- Normal ECG: Can be described as regular, rhythmical electrical impulses.
- Abnormal ECG: This is a sign of irregular heartbeats, heart tension, or a previous heart attack.
- Normal Echo: The normal heart functioning and movement of the valves.
- Abnormal Echo: An abnormal Echo is an indication of structural flaws, a feeble muscle, or fluid accumulation.
Your cardiologist will interpret the findings and provide details as well, and might recommend follow-up tests.
Conclusion: Choosing the Right Heart Test Matters
The difference between an ECG and an echocardiogram will help you make better decisions about your heart health. An ECG detects an electrical defect, whereas an Echo visualises a physical and functional defect. To be fully diagnosed, your physician might order both. Regular check-ups or recognising the symptoms, and early testing will avoid severe heart complications.

Frequently Asked Questions
Which test is better, an echo or an ECG?
Both are valuable. ECG detects electrical problems, while echo evaluates structural and functional heart health. Doctors often recommend both for an accurate diagnosis.
Is an ECG and echo enough to detect heart problems?
Yes, together they detect most cardiac issues like arrhythmias, valve defects, or weak heart muscles. Further tests may follow if abnormalities appear.
Can both ECG and Echo detect heart blockage?
They can indicate possible blockages, but a coronary angiogram or stress test is required to confirm arterial blockages precisely.
How long does an ECG and Echo take?
An ECG takes about 5-10 minutes, while an echocardiogram typically lasts 20–45 minutes, depending on the complexity.
