ECG
A quick, painless test that records your heart's electrical activity to detect rhythm problems, heart strain and past heart attacks.
An Electrocardiogram (ECG or EKG) records the electrical signals that control your heartbeat. Small sensors (electrodes) are placed on your chest, arms and legs to capture this activity as a graph, which shows the rate and regularity of your heartbeat and can reveal signs of heart strain, past damage or rhythm abnormalities.
The test itself takes only a few minutes and is completely painless — no needles or radiation are involved. It is one of the first and most commonly used tests in evaluating heart symptoms because it is quick, non-invasive and widely informative.
An ECG is often done alongside a cardiology consultation and, depending on the findings, may be followed by further tests such as an Echocardiogram or TMT for a fuller picture of heart health.
| Aspect | Details |
|---|---|
| Duration | 5–10 minutes including electrode placement |
| Preparation | No special preparation; avoid applying oil or lotion to the chest before the test |
| What Happens | You lie down while electrodes are placed on your chest, wrists and ankles; the machine records your heart's electrical activity for a few seconds |
| Pain/Discomfort | None — the test is non-invasive and painless |
An ECG is recommended for a wide range of heart-related symptoms and as part of routine cardiac risk assessment.

No. An ECG is completely painless. You may feel a slight coolness from the electrode gel or a mild pull when the electrodes are removed, but there is no needle or discomfort involved.
No fasting is required for a routine ECG. You can eat and drink normally before the test.
Not entirely. A normal ECG is reassuring but doesn't rule out every heart condition — some problems only appear during physical exertion (better assessed with a TMT) or need imaging like an Echocardiogram. Your cardiologist will advise if further testing is needed.
An ECG records the heart's electrical activity, while an Echocardiogram uses ultrasound to show the heart's structure and how well it is pumping. They give different, complementary information and are sometimes done together.
