What can lead to misdiagnosis from an ECG tracing?

  1. Tracings filed in the correct patient record

  2. Too long ECG performance

  3. Inaccuracy in the ECG tracing

  4. Order being marked as STAT

The correct answer is: Too long ECG performance

The correct answer highlights that too long of an ECG performance can lead to misdiagnosis. When an ECG is prolonged, it can capture extraneous data that may not be relevant to the patient's current health status. This might include interruptions caused by patient movement, artifacts due to electrical interference, or other non-cardiac related disturbances. As a result, clinicians may misinterpret these artifacts as cardiac events, leading to a misdiagnosis. In contrast, other scenarios, such as having tracings filed in the correct patient record, generally support accurate medical assessment. The accuracy of the ECG tracing (as noted in another option) is critical; however, a long-duration recording can blur key indicators and enhance the potential for misdiagnosis. Additionally, an order marked as STAT indicates urgency but does not inherently alter the quality or interpretation of the ECG itself. Thus, the length of the performance is a significant factor that can negatively impact the diagnostic process.
