What is an ECG?
An ECG is a painless and non-invasive test that measures and records your heart’s electrical rhythm and activity. It involves placing small sensors, called electrodes, on your chest, arms, and legs to detect the electrical impulses produced by your heart.
The test usually takes around five minutes to complete and is performed in a clinic or hospital setting. The results are then printed or displayed on a monitor for the doctor to analyse.
Why is an ECG Important?
An ECG is an essential diagnostic tool for identifying various heart conditions. It can help detect abnormalities in the electrical activity of the heart, such as irregular heartbeats (arrhythmias), damaged heart muscle, and inadequate blood flow to the heart (coronary artery disease).
What to Expect During an ECG
Before the test, it is essential to inform your doctor about any medications you are taking, as some can affect the results. The procedure itself is straightforward and does not require any special preparation. You will be asked to lie still while the electrodes are attached to your skin. You may also be asked to take deep breaths or hold your breath for a short period during the test.
After the test, the electrodes will be removed, and you will be advised to resume your regular activities. Your doctor will review the results and discuss any abnormalities or next steps, if necessary.
