Do I need to take off my upper body clothing for an ECG?

ECG examination usually requires removing the upper clothing to ensure proper placement of the electrodes and accurate test results. The ECG records the heart's electrical activity by attaching electrodes to the chest, arms, and legs. Clothing may interfere with the contact between the electrodes and the skin, affecting the quality of the recording. Therefore, removing the upper garment helps ensure the electrodes adhere closely to the skin and improves the reliability of the data. Additionally, requirements may vary slightly between hospitals or devices, but removing the upper clothing is a common practice.

To ensure a successful ECG examination, it is recommended to understand the specific requirements of the hospital beforehand and wear loose, easily removable clothing. Before the test, keep the skin clean and dry, and avoid applying oils or excessive sweat that may interfere with electrode adhesion. Follow the instructions of the medical staff upon entering the examination room. If you feel uncomfortable or embarrassed, inform the staff, who will provide appropriate measures to protect your privacy. After the examination, dress promptly to avoid catching a chill. If you are unable to remove clothing due to medical or physical reasons, inform the doctor in advance to discuss alternative arrangements.
