ECG Test Purpose, Procedure, Sample Report & Price [2026]

ECG Test (Electrocardiography) examines the abnormalities in the heart rhythm due to heart diseases. It may also indirectly indicate the cause of Cardiac arrest, irregular heartbeat, and insufficient oxygen supply to the heart. It is a non-invasive, painless and graphical information result based test. This test is usually prescribed to mid-aged and older patients. Its price in India ranges from Rs 150 to Rs 400.

Your doctor can recommend an ECG test to diagnose:

• Increased or Decreased heartbeat
• Irregular heartbeat
• Blood clot
• Defects related to heart since birth
• Heart attack

What happens in an ECG Test?

The ECG (Electrocardiogram) is a simple diagnostic test that checks the heart’s electrical activity. Electrodes attached to the skin detect the electrical signals produced by the heart each time it beats. A machine records all these signals. Depending on the results, a doctor can conclude whether these signals are normal or abnormal.

The respect and privacy of the females during the process are maintained well, and usually, the female technician does it for women.

Types of ECG

There are different types of ECG tests. Depending on your problem, your doctor may recommend any given ECG.

1. Resting ECG: The test is done while you lie down. The resting ECG is a simple, painless and quick test. It can diagnose Ischemia and myocardial infarction.
2. Stress or exercise ECG: This test is carried out on a treadmill. This gives an idea of the functionality of heart under the stressful conditions. 
3. Ambulatory ECG: It is a portable machine attached to your waist. It detects the heart functioning under normal conditions. 

Purposes of the ECG:

What does ECG detect?

There are the following purposes of the ECG. Let you have a glance at them:

• Diagnosis of Hypertrophic cardiomyopathy (HCM): Irregular heartbeat, Ischemia, arteries blockage, heart failure. 
• Routine test: The EKG can also be used as a routine test in certain age groups. It monitors heart health after heart surgery. It is also used as a follow-up test after a patient encounters a heart attack.
• Determining the pacemaker’s function: The pacemaker is a device inserted in the chest if you are a heart patient or have a compromised heart function. 
• To monitor your heart health if you are under medication: It helps to monitor the status of your heart if you are taking some medication that alters heart function. 

When to go for ECG?

There are the following conditions under which you must go for ECG:

• Abnormally increased heartbeat: Sinus Node is an inbuilt and natural pacemaker. It initiates the heartbeat. Sinus Tachycardia and Atrial flutter are the disorders that contribute to the increased heartbeat.
• Irregular heartbeat: It is also known as PSVT, and it occurs due to a short circuit rhythm development in the heart’s upper chamber. The rapid heartbeat starts irregularly and stops abruptly. 
• Imbalanced Calcium levels: Hypokalemia is the deficiency of Calcium ions in the heart muscles. While Hyperkalemia is the excess amount of Calcium in the heart muscles. Both conditions cause irregularity in the heartbeat. 
• Blood Clot in the Heart: Coronary Embolism is the condition in which a blood clot jams the artery of a heart.
• Heart disorders since birth
• Heart attack: It stands for Myocardial infarction ECG. It helps diagnose heart conditions during a heart attack.

ECG Test Preparation

• The ECG test requires no special preparation.
• Fasting is also not required.
• The patient should tell the physician about the medicines he or she is taking. 

ECG Test Procedure

The stepwise procedure of the ECG test. 

• You have to remove your upper clothing. Shave your chest hair, if required.
• There are small ECG electrodes attached to the arms, legs, and chest. All these sensors are connected to the machine. Technician would place a total number of 12 electrodes. This placement is known as Leads placement.
• You need to remain relaxed and still during the procedure. The Lab technician may ask you to hold your breath for a few seconds.
• The heart activity is displayed on paper in graphical form.
• The entire procedure takes 10 to 15 minutes.

Result interpretation

ECG result is represented in a graphical form. The cardiologist or heart specialist checks the report carefully.

The table below lists the normal values and indications for abnormal values in an ECG test.

Value	Conclusion
60 to 100 beats per minute	Normal
More than 100 beats per minute	Tachycardia
Less than 60 bpm beats per minute	Bradycardia

Some of the various Abnormal heart problems that ECG can diagnose include:

• Bradycardia: This refers to the decreased heart rate
• Tachycardia: This refers to an increase in heart rate.
• Ischemia: It denotes cell death due to the insufficient oxygen supply.
• Myocardial infarction: It is known as a heart attack. There is a sudden obstruction in the blood supply to the cardiac muscles.
• Heart diseases since birth: like WFW Parkinson’s syndrome involve an error in the electrical conducting system.
• Arrhythmias: It is rapid, slow or irregular heartbeats.
• Heart damage due to coronary occlusion (blockage in arteries).
• Improper or compromised blood supply to the heart.
• Abnormal heart position.
• Cardiac inflammation in layers of the heart, Endocarditis, Myocarditis, and Pericarditis.
• Cardiac arrest during the intensive care monitoring.

The Normal vs Abnormal result

The graphical representation of the Normal and Abnormal ECG report is given below. However, If your ECG result is abnormal, your doctor will recommend certain other tests or repetition of ECG.

 

Other Tests linked with the Heart or ECG Test:

The Doctor sometimes provides the following tests to the heart patients to get a clear idea of the progression of the disease.

• Physical examination: Listening to heart sounds using a stethoscope.
• Magnetic resonance imaging (MRI) or computerised tomography (CT) scans the heart.
• Blood tests like the lipid profile test and D-dimer test.
• Cardiac Catheterisation: It is the insertion of a catheter through the blood vessels of the groin or wrist into the heart.
• Echo Test: It is also known as electrocardiography, and it involves the use of ultrasound waves.
• Stress Echo Test: This test measures the stress that a heart patient can bear. The Dobutamine stress test is a variation of this test in which a substance is given to a patient that faces some difficulty in running while testing.
• Treadmill test (TMT Test): It is performed for the diagnosis of an abnormal heart rhythm of the heart patient.
• Coronary Angiography Test: It is an invasive test involving catheter insertion into the arteries.
• Holter Test: In the Holter test, the patient wears a chest bearable digital device for recording the heartbeat however it does not give a satisfactory result.

Cardiac Arrest v/s Heart Attack

• Cardiac arrest and heart attack are not the same. 
• There is a cause and consequence relationship between both.
• Cardiac arrest indicates the moment when the heart stops beating.
• Heart attack is the most common cause of Cardiac arrest.
• In a heart attack, there is damage to the heart muscle due to insufficient oxygen supply.
