Question

A medical assistant is calibrating an EKG machine, which of the following should the assistant identify as a standard speed of the recording?

1) 25 mm/s
2) 50 mm/s
3) 100 mm/s
4) 200 mm/s

Answer 1

The standard speed for EKG machine recordings is 25 mm/s, which is used to accurately record the heart's electrical activity.

Step-by-step explanation:

The standard speed of an EKG (electrocardiogram) machine during a recording is 25 mm/s. This is the default speed at which the machine records the electrical activity of the heart. Recording at this speed allows for accurate representation of the heart's rhythm and timing on the EKG tracing. The EKG paper moves at this speed past the stylus, translating the electrical signals into waves on paper for analysis. Some situations may require a faster speed, such as 50 mm/s, to better define certain details of the heart's electrical activity, but 25 mm/s is the standard and most commonly used speed.
