For an accurate EKG reading, the patient should be in a supine position, relaxed, and at rest. This position minimizes muscle tension and ensures that the body's electrical impulses are recorded accurately without interference from movements. When a patient is lying flat on their back, it allows the electrodes to obtain a clear and stable reading of the heart's electrical activity, which is essential for effective diagnosis and monitoring.

Being relaxed is also crucial, as tension can produce artifacts on the EKG that may mimic or obscure underlying cardiac conditions. A patient who is tense or experiencing anxiety may have increased muscle activity, which can distort the EKG tracing. Additionally, lying supine helps maintain proper electrode placement by providing a consistent and accessible surface for attachment, further ensuring an accurate result.
