A patient lies on a blue-draped operating table, covered with a gray and white blanket and wearing a striped gown and a blue surgical cap. Electrocardiogram (ECG) leads are attached to the patient's chest. A person in lavender scrubs and a face mask kneels beside the patient, holding a device with a long, thin probe. Another person in lavender scrubs adjusts the patient's arm. Stainless steel medical equipment and tables are visible in the background. The floor is light green.
