A 72-year-old woman underwent thoracoscopic partial lung resection for lung cancer in the right upper lobe 10 years ago. At her current presentation, she underwent bronchoscopic examination due to the presence of a solid tumor near the staple line. During the procedure, the electrocardiogram monitor showed ST depression and bradycardia; hence, the study was stopped and emergency cardiac catheterization was performed. Coronary angiography showed no significant stenosis nor abnormalities in left ventricular systolic movement. Her symptoms improved after cardiac catheterization and there was no symptom relapse. Since ST changes during bronchoscopic examination can be caused by inappropriate techniques during the examination, standardized techniques should be used to reduce the burden on the patient.
