Which of the following correctly describes the function of the gain setting on the EKG machine?
A)It filters out extraneous noise and artifact.
B)It controls the speed of the recording.
C)It sends a message to the physician about any abnormality on the EKG.
D)It regulates the height of the complexes.

Question

Quizplus · Accepted Answer

The gain setting on the EKG machine regulates the height of the complexes. It determines the amplification of the electrical signals from the heart, which changes the size of the waveforms on the EKG tracing. Higher gain settings amplify the signals more, resulting in larger waveforms, while lower gain settings amplify the signals less, resulting in smaller waveforms.
