Hi all,
Need help with this:
What is the difference that you see on a EKG when you have non-transmural MI vs. transmural MI?
a) In transmural MI the Q wave is amplified, and the R wave is depleted making the QRS complex look inverted
b) In non-transmural, the T wave is absent
c) In transmural the P wave is delayed
d) In non-transmural the QRS complex is wider than normal
Based on my research it seems that none of the options should be selected because research has been done to show that no visible differences in EKG can determine non-transmural versus transmural. But I have to select one of the answers and I believe it is A. Please let me know your thoughts. - Thanks
Hello! It seems like you've done some research on the topic. You are correct that there is often no visible difference on an EKG that can definitively determine whether an MI is non-transmural or transmural. However, in this case, you are asked to select the best answer among the given options.
Let's analyze each answer choice to determine the most accurate option:
a) In transmural MI, the Q wave is amplified, and the R wave is depleted, making the QRS complex look inverted.
b) In non-transmural MI, the T wave is absent.
c) In transmural MI, the P wave is delayed.
d) In non-transmural MI, the QRS complex is wider than normal.
Based on the information you provided, it seems like the best answer would be (a). In a transmural MI, there may be pathological Q waves and changes in the QRS complex, such as QRS complex inversion due to the affected myocardium. However, it's important to note that these changes may not always be present or reliable indicators.
Remember, while (a) seems to be the closest option to answer the question, it is essential to understand the limitations of interpreting MI types solely based on EKG findings. In some cases, additional diagnostic tests, including cardiac enzymes and imaging studies, may be necessary for a more accurate diagnosis.
I hope this clarifies your query! Let me know if you need further assistance.
