The image shows a close-up of a medical procedure, specifically an electrocardiogram (ECG) or EKG, which is a test that measures electrical activity in the heart. The ECG is performed by attaching electrodes to the patient's chest and recording the electrical signals. The electrodes are typically placed on the patient's chest, covering the area from the upper arm to the lower abdomen. The ECG provides valuable information about the heart's function, including its rhythm, strength, and overall health.
