Why do people need to sit as still as possible during the recording of an ECG?

ECG recordings are based off of dipoles of electrical activity on the heart as measured through the detection of small electrical wave changes on the skin. This is a very precise measurement and especially with 12-lead monitors, movement can create "artifact" or false dipole readings because of either muscle activity or manipulation of the leads. This can mask findings that could be important for the care of the patient. Healthcare professionals are trained to recognize artifact, but the patient should remain as still as possible so the machine can get a good reading.
