Nurses are often responsible for performing the ECG itself. This includes: 1. Placement of Electrodes: Correct placement of electrodes is crucial for accurate readings. Nurses must be familiar with the standard 12-lead ECG placement. 2. Ensuring Patient Comfort: During the ECG, nurses must ensure that the patient remains still and relaxed to avoid muscle artifacts. 3. Monitoring the Procedure: Nurses observe the ECG monitor for any immediate abnormalities during the test, which may require urgent attention.
