What is ECG?

ECG stands for Electrocardiogram. It’s a simple test that helps check the heart rhythm & electrical activity and detect signs of heart disease.

Small electrode patches are attached to the skin of the chest, arms, and legs which help record the electrical activity of the heart. Heart signals are recorded by a machine, which is then examined by a doctor to check if they’re normal or abnormal.

When is ECG Used?

ECG is used in the investigation & identification of a potential heart problem in a person who is experiencing symptoms like chest pain, shortness of breath, palpitations, dizziness, etc. It’s generally recommended by a doctor who thinks there might be an issue related to the heart.

Why it’s done

An electrocardiogram is a painless, non-invasive way to help diagnose many common heart problems. A health care provider might use an electrocardiogram to determine or detect:

  • Irregular heart rhythms (arrhythmias)
  • If blocked or narrowed arteries in the heart (coronary artery disease) are causing chest pain or a heart attack
  • Whether you have had a previous heart attack
  • How well certain heart disease treatments, such as a pacemaker, are working

You may need an ECG if you have any of the following signs and symptoms:

  • Chest pain
  • Dizziness, lightheadedness, or confusion
  • Heart palpitations
  • Rapid pulse
  • Shortness of breath
  • Weakness, fatigue, or a decline in the ability to exercise

What does the ECG test show?

The ECG test results show your heart rate and rhythm, which are examined by a doctor to detect anything unusual.

Normal ECG test results generally comprise:-

  • Heart rate: 60-100 beats per minute
  • Heart rhythm: consistent & even

Abnormal ECG test results may indicate:-

  • Damage or changes to the heart muscle
  • Past or current heart attack
  • Poor blood supply to the heart arteries
  • Heart enlargement
  • Congenital heart defect
  • Fluid or swelling in the sac around the heart
  • Myocarditis (inflammation of the heart)
  • Arrhythmias (abnormal heart rhythms)
  • Changes in the number of electrolytes like potassium & calcium in the blood


To conclude, ECG is a simple, risk-free & painless test that plays a crucial role in the diagnosis and monitoring of heart-related problems globally.
