Understanding Electrocardiogram (ECG) - Definition, Purpose, and Procedure

An electrocardiogram, commonly known as an ECG, is a medical test that measures the electrical activity of the heart. It is a non-invasive and painless procedure that helps detect various heart conditions, such as arrhythmias and heart attacks.

During an ECG, small electrodes are attached to the chest, arms, and legs of the patient, which record the electrical signals generated by the heart. The recorded signals are then printed onto paper or displayed on a screen, which a doctor or a trained technician interprets.

The purpose of an ECG is to detect any abnormal heart rhythms, such as bradycardia or tachycardia, and to diagnose conditions, such as heart attacks, atrial fibrillation, and heart failure. It is also used to monitor the effectiveness of treatments for heart conditions and to assess the risk of cardiovascular disease.

ECGs are commonly performed in hospitals, clinics, and doctor's offices, and the procedure typically takes less than 10 minutes. The test is safe and does not require any special preparation or aftercare.

In conclusion, an ECG is a useful diagnostic tool that can help detect various heart conditions. If you have any concerns about your heart health, consult with your doctor, who can recommend an ECG or other appropriate tests to evaluate your heart function.
