Which of the following is a hallmark sign of MI on an ECG? A) ST-segment elevation B) T-wave inversion C) U-wave D) P-wave flattening
Understand the Problem
The question is asking which option represents a hallmark sign of myocardial infarction (MI) as shown on an electrocardiogram (ECG). The aim is to identify the correct characteristic from the provided choices.
Answer
ST-segment elevation
The final answer is ST-segment elevation.
Answer for screen readers
The final answer is ST-segment elevation.
More Information
ST-segment elevation is a classic indicator of myocardial infarction on an ECG, reflecting acute ischemia.
Tips
Confusing ST-segment elevation with T-wave inversion, which can occur in different contexts.
