What is indicated by a depressed ST segment in a 6-second strip?

A depressed ST segment in a 6-second EKG strip is indicative of myocardial ischemia, which means that there is a lack of adequate blood flow to the heart muscle. It can suggest that the heart is not receiving enough oxygen, possibly due to coronary artery disease or other factors affecting blood supply. In some cases, ST segment depression may also indicate the presence of ventricular strain or may occur during exercise or stress testing when the heart's demand for oxygen exceeds its supply. It's important for healthcare providers to recognize this change because it can be a precursor to more serious cardiac events.

Understanding the significance of various ST segment changes is crucial in the interpretation of EKGs and for making informed clinical decisions. Thus, acknowledging that the correct answer is "depressed" accurately reflects the clinical implications of this specific EKG finding.
