Question

A patient reports having crushing chest pain that radiates to the jaw. You administer sublingual nitroglycerin and obtain a 12 lead EKG. Which of the following EKG findings confirms your suspicion of a possible myocardial infraction?

A. absent Q wave

B. QRS widening

C. absent P-wave

D. ST segment elevation

Answer 1

The ST segment elevation on an EKG confirms the suspicion of a possible myocardial infarction (MI). Option d.

Step-by-step explanation:

An elevation of the ST segment above baseline on an EKG confirms the suspicion of a possible myocardial infarction (MI). Option d.

Other EKG findings associated with MI include an enlarged Q wave, which may indicate a MI.

It is important to note that interpreting an EKG requires training and experience, and a comprehensive diagnosis of a MI usually involves additional tests such as echocardiography or cardiac magnetic resonance imaging, as well as blood tests to detect elevated levels of enzymes released by damaged cardiac muscle cells.
