Electrocardiogram (ECG)
An electrocardiogram, also called an ECG (or EKG), is a simple and painless test that records the heart's rhythm and electrical signals.
Special Instructions
Do not wear body lotion or perfume on the day of your test.
There are no dietary restrictions before the test.
Continue taking any prescribed medications before and after the test unless otherwise advised by your doctor.
During the Test
An electrocardiogram is a painless and very safe procedure performed while you lie face-up on an examination table. Here's what to expect:
A technician will attach sticky patches called electrodes to the skin on your chest, arms, and legs.
For male patients, areas of the skin may need to be shaved to help the electrodes stick properly.
Female patients will be provided with a gown.
An ECG machine will record the electrical signals of your heart and display them on a screen.
The test typically takes about 10–15 minutes.
After the Test
After completing the ECG:
The technician will remove the electrodes.
You may notice mild redness where the patches were attached; this usually resolves on its own without treatment.
You can resume your normal daily activities immediately.
Test Results Interpretation and Follow-Up:
Please note that the technologists performing your test or the staff will not be able to discuss the results with you. All test results will be interpreted by a cardiologist and sent to the referring physician. You can then discuss the results and any further steps with your physician.
If your test was ordered by the cardiologist you have seen for consultation at our clinic, the consulting cardiologist will review the results and will communicate with our administrative team regarding the next steps.
