, How can an EKG help in diagnosing atrial fibrillation?
✔✔It can show an irregularly irregular rhythm and absence of distinct P waves.
What might a high ST segment depression indicate on an EKG?
✔✔It can indicate myocardial ischemia or insufficient blood flow to the heart muscle.

What does the U wave represent in an EKG?
✔✔It may represent the repolarization of the Purkinje fibers, though it is not always present.
What is the role of the PR interval in EKG interpretation?
