ECG stands for electrocardiogram, which is a medical test used to measure and record the electrical activity of the heart.

During an ECG test, small electrode patches are placed on the skin of the chest, arms, and legs. These electrodes detect the electrical signals produced by the heart and transmit them to a machine that records the signals as a series of lines or waves on a graph.

ECG tests are used to diagnose a variety of heart conditions, including arrhythmias (irregular heartbeats), heart attacks, and heart disease. An ECG can also be used to monitor the effectiveness of heart medications or to check for any abnormalities before undergoing surgery.

ECG tests are non-invasive and typically take only a few minutes to complete. They are performed by healthcare professionals such as doctors, nurses, or technicians.
