How should an electrocardiogram (EKG/ECG) be conducted?

An electrocardiogram (EKG/ECG) is most effectively conducted when the patient is at rest, ensuring that the heart's electrical activity is measured accurately without any interference. This resting state reduces the likelihood of extraneous electrical noise that can arise from movement, anxiety, or other activities. Proper placement of electrodes is crucial to capture a clear and accurate representation of the heart's electrical signals. When electrodes are positioned correctly on the patient's chest and limbs, they can detect the heart's rhythm and any abnormalities with greater precision.

Conducting the test in other positions, such as standing or lying on the stomach, may prevent optimal contact and alignment of the electrodes, potentially leading to inaccurate readings. Additionally, performing the EKG while the patient is actively exercising is typically reserved for a specific type of test known as an exercise stress test, which is designed to assess how the heart functions under stress rather than providing a baseline reading. Therefore, ensuring the patient is at rest and that electrodes are correctly placed is fundamental to obtaining valid EKG results.
