Answer 1

Answer:

The type of data that is recorded by electrocardiogram is the electrical activity of the heart.

Explanation:

The heart functions through a nerve structure —the sinus node, the atrioventricular node and the His-Purkinje system— which determine the functioning of the organ through electrical activity.

The electrocardiogram, or EKG, is a device that records the electrical activity of the heart. This allows us to know any alteration in said activity, such as arrhythmias, interruption of electrical impulses or alteration of the heart's anatomy.

In order for the EKG to be able to record the electrical activity, electrodes must be placed on the limbs and chest, which are the sensors in charge of receiving the information of the heart's electrical activity.

Other options are not correct because:

• The amount of oxygen in the blood is measured by using oximeters or blood gas measurement.
• The sound  or the force from the heart beating can be recorded by auscultation with a stethoscope.
