Which term is the recording of the heart's electrical activity?

Explanation:
Recording the heart’s electrical activity is called an electrocardiogram. The word comes from electro- (electric) + cardio- (heart) + -gram (record). An electrocardiogram captures the electrical impulses that coordinate heartbeats, producing a tracing that helps assess heart rhythm, rate, and potential problems such as arrhythmias or ischemia. The other terms refer to different ideas—endocarditis is an infection of the heart’s inner lining, erythema is skin redness, and electrocadiogram is not the standard spelling for this test and isn’t used to describe the recording of the heart’s electrical activity.
