True or False: Patient psychology can be more important in obtaining a diagnostic ECG than the mechanics of administering ECG.

The statement is true because patient psychology plays a significant role in obtaining a diagnostic ECG. When patients are anxious or fearful about the procedure, their stress levels can impact physiological responses, such as heart rate and rhythm. This can lead to discrepancies in the ECG readings, potentially resulting in misinterpretation by the clinician.

Creating a calm and reassuring environment is essential for minimizing anxiety and aiding in accurate readings. Effective communication, explaining the procedure clearly, and addressing any concerns can significantly enhance cooperation and relaxation, which, in turn, helps ensure that the ECG is as informative and accurate as possible.

While the mechanics of administering an ECG are undoubtedly important—ensuring that electrodes are placed correctly and that the machine is functioning properly—addressing the patient's psychological state is equally crucial. An understanding of the patient's mindset can lead to better cooperation and yield more reliable diagnostic data.
