Can outside noise interference, such as a train or large truck, cause artifact in an EKG reading?

The presence of outside noise interference, such as from a train or large truck, can indeed cause artifact in an EKG reading. This is primarily due to the sensitive nature of the EKG equipment, which is designed to detect very low electrical signals generated by the heart. When external noises occur, particularly those that are loud and abrupt, they can create electrical interference or vibrations that may be picked up by the EKG machine. This results in artifacts, which can mimic or obscure the true heart signals, leading to inaccurate readings.

Understanding this concept highlights the importance of ensuring a quiet environment during EKG monitoring. A clear and controlled setting minimizes the risk of such interference, allowing for more reliable and accurate EKG readings. Thus, it is essential for healthcare providers to recognize that external mechanical noise can impact EKG results.
