Question

an electrocardiogram will always detect a myocardial infarction. true false

Explanation:

An electrocardiogram (ECG) is a useful tool for detecting myocardial infarction, but it is not always conclusive. In some cases, especially in the early stages of a heart attack or in certain types of myocardial infarctions (such as sub - endocardial infarctions), the ECG may not show the classic changes immediately. Other diagnostic tests like cardiac enzyme markers (e.g., troponin) are often used in conjunction with the ECG for a more accurate diagnosis.

B. False
