How do you operate a ECG machine?

To operate an ECG machine, first ensure the patient is in a comfortable position and has been prepared by cleaning the skin and applying electrodes to specific locations on the chest, limbs, and sometimes the back. Turn on the ECG machine and select the appropriate lead configuration for the test. Instruct the patient to remain still and relaxed while the machine records the electrical activity of the heart, which typically takes just a few minutes. Once completed, review the printed ECG tracing for any abnormalities and ensure proper documentation.
