ECG

ECG stands for electrocardiogram, which is a diagnostic test used to evaluate the electrical activity of the heart. An ECG machine records the electrical impulses that are generated by the heart as it beats, and produces a graph that shows the timing and strength of these impulses.

The ECG can help to detect a variety of heart conditions, including arrhythmias (irregular heartbeats), heart attacks, and problems with the heart's structure or function. It is a non-invasive and painless procedure that involves attaching electrodes to the skin on the chest, arms, and legs.

During an ECG, the patient lies still on a table while the machine records the electrical signals from the heart. The procedure typically takes only a few minutes to complete, and the results are usually available to the doctor immediately.

Interpreting an ECG requires specialized training, and should only be done by a trained healthcare professional. However, in general, a normal ECG will show a regular pattern of electrical activity that reflects the normal function of the heart. Abnormalities in the ECG can indicate a problem with the heart, and may require further testing or treatment.
