What is an electrocardiogram (ECG)?
An electrocardiogram (ECG) is an essential medical test that creates a graph representing the heart's electrical activity. Although developed in 1887, the ECG remains an extremely important tool in modern medicine, allowing a detailed analysis of heart function.
Which diseases can an electrocardiogram detect?
An ECG is fundamental for detecting a range of cardiac abnormalities, such as heart attacks, arrhythmias and enlargement of parts of the heart. The test can also identify changes that indicate problems outside the heart, such as anemia, mineral level disorders, dehydration and even strokes. In summary, a normal electrocardiogram is an excellent indication that many functions of your body are in good condition.
How is an electrocardiogram performed?
The ECG procedure is simple and quick. First, the patient's skin is cleaned with alcohol and/or a specific gel to remove any oil. This helps ensure the quality of the recording. Electrodes and electrical leads are then placed in the standard ECG recording positions. During the test, the patient must remain still to ensure an accurate recording of the heart's electrical activity.
