Which abbreviation represents the test used to record the heart's electrical activity?

Explanation:
Recording the heart’s electrical activity is done with an electrocardiogram, abbreviated ECG (also called EKG). It measures the electrical impulses as they move through the heart, giving a graph of heart rate and rhythm and revealing issues like arrhythmias, conduction problems, or ischemia. The other items don’t capture electrical activity: a chest X-ray images chest structures, date of birth is just demographic information, and a do-not-resuscitate order relates to resuscitation preferences. So ECG/EKG is the correct test.
