What component checks the voltage that the EKG machine is utilizing?

The component that checks the voltage that the EKG machine is utilizing is standardization. This process ensures that the EKG machine is set to a specific reference voltage, which allows for consistent and accurate readings across different machines and tests. In EKG practice, standardization is crucial because it aligns the output of the EKG machine with a known standard, enabling healthcare providers to interpret the results with confidence.

During standardization, the EKG machine typically generates a standardized waveform, which includes a known amplitude and duration. This not only helps in maintaining the accuracy of the recordings but also aids in comparing EKGs from different sessions or machines effectively. Therefore, when calibrating or setting up an EKG machine, checking that it has been properly standardized is essential to ensure that the voltages being used for the cardiac electrical activity recordings are appropriate and accurate.
