ECG
ECG (electrocardiogram) is a medical test used to record the electrical activity of the heart. It is used to diagnose heart problems, including arrhythmias, cardiac arrests, myocardial infarctions, and other heart diseases. The results are displayed as graphs on paper or on a screen, and doctors use them to assess heart function and identify problems.
HOW IS ECG PERFORMED?
ECG is performed by attaching electrodes to the patient's body. The electrodes are usually placed on the chest, arms, thighs, and shoulders of the patient. Then, the electrical impulses generated when the heart beats are recorded and displayed as waves on a screen or paper. This recording is called an electrocardiogram and can show the speed, strength, and rhythm of heart contractions. An ECG can be performed in a few seconds and usually does not cause any discomfort.
HOW TO PREPARE FOR ECG?
Preparing for an ECG involves the following steps:
- Inform your doctor about your previous medical conditions, including drug allergies, pregnancy, and heart diseases.
- Do not smoke for at least an hour before the test as tobacco can affect the results.
This preparation will ensure accurate and useful results from the ECG. If you have any questions about preparing for the examination, consult your doctor.
