When performing an EKG, where should the electrodes be placed on the arms?

When performing an EKG, the placement of the electrodes is crucial for obtaining accurate readings. The correct approach is to place the electrodes with the tabs facing downward towards the body. This orientation allows for better contact with the skin, which can improve the quality of the electrical signals captured during the test. Proper electrode placement helps minimize interference and ensures that the EKG reflects the heart's electrical activity accurately.

In contrast, placing the tabs upward could create an improper connection that may affect signal quality. Similarly, using only one tab on either arm would not provide the necessary bipolar leads required for a complete analysis of the heart's electrical activity, leading to incomplete or inaccurate data. Therefore, ensuring the tabs face downward and utilizing both arms appropriately is essential for effective EKG monitoring.
