Question

Quizplus · Accepted Answer

A cardiograph is specifically an instrument used for recording the heart's electrical activity, typically by means of electrocardiography (ECG). While a recording of the heart beat is a common result of using a cardiograph, it is not the definition of the tool itself. A heart technologist is a medical professional who works with cardiac procedures and tests including working with cardiographs, but this is not a definition for the term. The action of taking a heart recording is also not a complete definition of the term cardiograph.
