Certified Rhythm Analysis Technician (CRAT) Practice Exam 2025 - Free CRAT Practice Questions and Study Guide

The primary responsibility for recording ECG (electrocardiogram) preliminary findings lies with the technician. Technicians are specifically trained in the use of ECG equipment and in the proper techniques for obtaining accurate readings. They have a thorough understanding of cardiac anatomy and physiology, which enables them to ensure that the electrode placement is correct and that the readings are performed under optimal conditions to minimize artifacts.

Technicians typically conduct the procedure and ensure that the ECG machine functions correctly. They also provide immediate feedback on the readings and may be responsible for preparing the initial analysis, which is crucial for timely medical decision-making. While nurses and physicians may have roles in interpreting ECGs and assessing clinical implications, it is the technician who usually handles the preliminary recording of the data. Supervisors may oversee operations but are generally not involved in the direct recording of ECG findings.
