ECG stands for electrocardiogram. It is a medical test that measures the electrical activity of the heart. The test records the electrical impulses generated by the heart as it beats, providing valuable information about its rhythm, rate, and overall function. Here are five frequently asked questions (FAQs) about ECG:
During an ECG, small metal electrodes are attached to specific locations on your chest, arms, and legs using adhesive patches. These electrodes are connected to an ECG machine that records the electrical signals produced by your heart. The test is painless and typically takes just a few minutes to complete.
ECGs are used to diagnose various heart conditions and abnormalities. They can detect irregular heart rhythms (arrhythmias), signs of a heart attack, heart muscle damage, structural abnormalities, conduction system problems, and other heart-related issues. ECGs are also routinely performed as part of a general health check-up.
No, ECG is a non-invasive and safe test. It does not involve the use of radiation. The electrodes attached to your skin may cause mild skin irritation in some cases, but this is temporary and usually resolves quickly after the test.
In most cases, there is no specific preparation required for an ECG. However, it is advisable to wear loose-fitting clothing that allows easy access to the areas where the electrodes will be placed. You may be asked to avoid applying oils, lotions, or creams to your chest on the day of the test, as they can interfere with the electrode connections.
While an ECG is a valuable diagnostic tool, it may not detect all heart problems. Some conditions, such as intermittent arrhythmias or blockages in the coronary arteries, may not be evident during a standard ECG. In such cases, additional tests, such as exercise stress tests, echocardiograms, or cardiac catheterization, may be required for a more comprehensive evaluation.
