Why not T wave
Question:
A 45-year-old female presents to the emergency department with a 2-day history of weakness and muscle cramps. She reports having a poor appetite and has been experiencing vomiting and diarrhea for the past week. On examination, she appears lethargic and her blood pressure is low. Her blood results show hypokalaemic. Which of the following is least likely to be seen in the EKG/ECG?
Options:
A)Prolonged QT interval
B)ST depression

Hi. Thanks for the question.
The reason why it is not flat T waves as it is hypokalemia, and the question asks what is the least likely to be seen- hence the answer is Delta waves, which is seen in syndromes like WPW.
One thing to note is that this is a negative question (leask like), and is not usually indicative of the questions in the real exam, however it is still a good tool of learning.
Good luck ! :)
