Abstract:
Regadenoson is a pharmacologic stress agent that has been widely adopted as an alternative over other pharmacologic vasodilator agents due to its ease of use, patient tolerance, and safety profile. We report the case of dynamic ST-segment elevation electrocardiogram changes after regadenoson injection during an inpatient single-photon emission computed tomography myocardial perfusion stress test, with subsequent coronary angiography revealing the presence of hemodynamically significant coronary artery disease. Our findings confirm that transient regadenoson-induced ST-segment elevations are a marker for hemodynamically significant disease even in the setting of low-risk SPECT perfusion images.

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.
Purposes
Electrocardiogram
Three major waveforms are present in a typical ECG recording: the P wave, the QRS complex, and...
