Key result
T wave alternans preceded classical ischemic ST segment depression during a treadmill stress test, suggesting it can act as an early marker of myocardial ischemia.
Why the study?

Can T wave alternans precede ST segment depression as a marker of myocardial ischemia during a treadmill stress test?
T wave alternans during a treadmill stress test may serve as an early marker of myocardial ischemia, preceding classical ST segment depression.
May signal early ischemia before ST depression in stress testing; hypothesis-generating case report requires prospective validation.
We observed a case where T wave alternans preceded classical ischemic ST segment depression during treadmill stress test. T wave alternans is considered to suggest increased susceptibility to ventricular arrhythmias. Our case suggests that T wave alternans can also be a marker of myocardial ischemia and can precede classical ischemic ST segment depression during treadmill stress test.

A 2022 study conducted a case report in Myocardial ischemia (n=1). Treadmill stress test was evaluated on Electrocardiographic changes during treadmill test. T wave alternans preceded classical ischemic ST segment depression during a treadmill stress test, suggesting it can act as an early marker of myocardial ischemia.
