What is ECG and Echo Test?

About electrocardiogram (ECG)


An electrocardiogram (ECG) is a diagnostic test used to identify various heart conditions by measuring the heart's electrical activity.

During the procedure, small adhesive dots (electrodes) and wire leads are placed on the chest, arms, and legs. These leads connect to an ECG machine (electrocardiograph), which records the heart's electrical activity and displays it as a trace on a screen or paper.

Any irregularity in heart rhythm or rate, as well as damage to the heart muscle, can alter the heart's electrical activity. A physician will analyze the trace for specific indicators of different heart conditions. By this content explore the Difference between ECG and ECHO Test procedures, pivotal tests in cardiac assessment. Understand their distinct methodologies, applications, and roles in diagnosing heart conditions. 


Types of ECG Tests

  • Resting ECG: Conducted while the patient is in a comfortable position.
  • Stress ECG: Performed while the patient is running on a treadmill.
  • Ambulatory ECG: Involves attaching electrodes to a small portable device worn at the waist to monitor heart conditions for one or more days.

Why do I need an ECG test?


Your doctor may suggest an ECG test if:


  • You have an irregular heart rhythm.
  • You might have blocked heart arteries causing chest pain or heart attacks.
  • You've had a heart attack before.
  • You have a pacemaker or similar devices that need checking.


Signs that you might need an ECG include:


  • Feeling your heart flutter or skip beats.
  • Your heart beats too fast.
  • You struggle to breathe.
  • You have chest pain.
  • Feeling dizzy or confused.
  • Feeling weak or tired.
  • Feeling tired quickly when you exercise.


How is an ECG test done?

An ECG test, also known as an electrocardiogram, involves several steps and typically takes about 5-10 minutes. During the test, a technician places 10-12 small sticky pads on different areas of the patient's chest. These pads are connected to leads from the ECG machine.


The leads are important because they transmit data about the heart's electrical activity. This data is used to create a tracing that helps assess the patient's heart health. An ECG is particularly useful when patients have symptoms related to heart conditions.

Getting an ECG

Having an ECG is a simple test that usually doesn’t require any special preparation.


  • You can eat and drink as usual before getting an ECG, unless your doctor has told you otherwise.
  • Always tell your doctor about any medications you are taking before getting an ECG.
  • Inform your doctor if you have any allergies to adhesive tapes, as adhesive is used to attach the electrodes to your skin.
  • You will need to take off your upper clothing so that electrodes can be placed on your chest, arms, and legs. Wearing a separate top with pants or a skirt can make it easier to access your chest. If you wear a bra with underwire, you may need to remove it before the test, as it can interfere with the ECG reading.
  • For the ECG to work well, your skin should be clean, dry, and free of oils and lotions. Sometimes, the skin may need to be shaved if there is hair, as it can prevent the electrodes from sticking properly.

An echocardiogram, also known as an "echo," is a heart scan that helps doctors examine the heart and nearby blood vessels.

During an echo, a small device called a probe sends out sound waves that bounce off different parts of the body, creating echoes. These echoes are captured by the probe and transformed into a moving image displayed on a monitor.

This test is often requested by heart specialists or other doctors concerned about potential heart issues, such as your family doctor.

Typically performed in a hospital or clinic by a cardiologist or trained specialist known as a cardiac physiologist, an echo is different from an electrocardiogram (ECG), which checks the heart's rhythm and electrical activity.

For an in-depth understanding of What is ECG and ECHO Test? and their roles in diagnosing heart conditions, delve into our comprehensive guide on the topic. Read more to enhance your knowledge about these crucial cardiac diagnostic tools.

Why do I need an ECHO test?

An echocardiogram is used to diagnose and keep track of certain heart conditions. It examines the heart's structure and nearby blood vessels, studying how blood moves through them and assessing the heart's pumping chambers.


This test can identify:


  • Heart damage from a sudden blockage of blood flow during a heart attack.
  • Heart failure, where the heart doesn't pump enough blood at the right pressure.
  • Birth defects affecting normal heart function, known as congenital heart disease.
  • Issues with heart valves that control blood flow within the heart.
  • Cardiomyopathy, which involves thickening or enlargement of the heart walls.
  • Endocarditis, an infection of the heart valves.

Additionally, an echocardiogram can assist doctors in determining the best treatment for these conditions.

Types of Echocardiograms Include:

  • Transesophageal echocardiogram (TOE): A small probe is inserted down the throat into the gullet and stomach. Local anesthesia is used to numb the throat, and a sedative is given to help relax. Fasting for several hours may be required before the test.
  • Stress echocardiogram: This test is conducted during or immediately after exercising on a treadmill or exercise bike. Alternatively, it can be performed after receiving an injection of medication that increases heart activity.
  • Contrast echocardiogram: A harmless substance called a contrast agent is injected into the bloodstream before the echocardiogram. This substance enhances the visibility of the heart on the scan, resulting in clearer images.
