Letter to Editor: Misleading Exercise Tolerance Test Results

The current report documents the case of a 29-year-old sportsman who presented to our heart center with palpitation for evaluation with the exercise tolerance test (ETT). He had no risk factors and no known history of ischemic heart disease, cardiomyopathy, arrhythmia, or central nervous system disease. He had normal echocardiographic findings. The pretest probability for ischemic heart disease was low, but his test result was positive with a 1.5-mm ST segment depression in the lateral leads (V3-6) in stage III of the ETT. Consequently, the patient underwent coronary CT-angiography one day later, which showed that he had normal coronary arteries.
