Frequently Asked Questions
What is an ECG test?
ECG (Electrocardiogram) is a simple and non-invasive test that records the electrical activity of the heart. It helps doctors evaluate heart rhythm and detect possible heart problems.
Why is an ECG test done?
An ECG is performed to detect irregular heart rhythms, heart attacks, blocked arteries, enlarged heart chambers, and other cardiac abnormalities. It is also used to monitor heart health and the effectiveness of treatments.
How should I prepare for an ECG?
No special preparation is required for an ECG. You can eat and drink normally. It is advisable to wear comfortable clothing that allows easy access to your chest, arms, and legs.
Do I need to fast before an ECG?
Fasting is not required for a standard ECG test unless your doctor gives specific instructions.
Is an ECG test safe?
Yes, ECG is completely safe and painless. It does not use electricity or radiation inside the body; it only records the heart’s natural electrical signals.
What happens during an ECG test?
During the test, small adhesive electrodes are placed on your chest, arms, and legs. These electrodes are connected to a machine that records your heart’s electrical activity while you lie still for a few minutes.
How long does an ECG test take?
The actual recording takes only 5 to 10 minutes, and the entire procedure including preparation is usually completed within 15 minutes.
Is ECG painful?
No, ECG is painless. You may feel slight discomfort when the electrodes are removed, especially if you have body hair, but the test itself does not cause pain.
When will I get my ECG results?
ECG results are typically available immediately or within a short time after the test. A doctor will interpret the results and explain them to you.
What is the difference between ECG and 2D Echo?
ECG records the electrical activity and rhythm of the heart, while a 2D Echo uses ultrasound to create images of the heart’s structure and function. Both tests provide different but complementary information about heart health.
