Acute inferior myocardial damage can induce transient bradycardia and hypotension—the Bezold–Jarisch reflex, which is explained by the preferential distribution of vagal nerves in the inferior wall of the left ventricle. We report a 76‐year‐old man who showed a perfusion defect in the inferior wall with redistribution on exercise scintigraphy with thallium‐201. Of note, during exercise at an intensity of 100 watts, the patient's heart rate transiently decreased from 122 to 95 bpm in sinus rhythm, accompanied by ST‐segment depression. A diagnosis of coronary spastic angina was made since no stenotic lesions were observed on conventional coronary angiography.
