Which term denotes the instrument used to record the heart's electrical activity?

• A. Electrocardiogram
• B. Electrocardiograph
• C. Electrodes
• D. Interval

Answer: (B)

The instrument used to record the heart’s electrical activity is the electrocardiograph. It’s the device that captures the heart’s electrical signals and translates them into a tracings on a monitor or printout. The tracing itself is called an electrocardiogram, which is the recording produced by the electrocardiograph. The term electrodes refers to the sensors placed on the skin to pick up the signals, and an interval is a measured span of time on the tracing (like the time between waves). So the machine you use to record the signals is the electrocardiograph.
