Abstract:
We report a case of ST elevation myocardial infarction (STEMI) during head-up tilt testing (HUTT). A 54-year-old man was admitted to our emergency department after four episodes of syncope. Treadmill test and electrophysiological study were normal. During passive HUTT, the patient had inferolateral ST elevation. Coronary angiography showed two severe lesions in the right coronary artery and circumflex artery.

Exercise Stress Test
Exercise stress testing, commonly known as a treadmill test, is a noninvasive procedure used to evaluate cardiovascular function and diagnose heart conditions.
Definition
An exercise stress test measures the heart's response to exertion using a treadmill or stationary bicycle. Chest electrodes record the heart's electrical activity through an ECG, and blood pressure is monitored regularly.
